A strong motorcycle sprocket choice matches your bike’s exact fitment, chain size, and front or rear position; riders replacing a worn component should start with those details. This selection includes JT steel sprockets in several tooth counts, a rubber-cushioned front sprocket, a self-cleaning rear design, and two more specialized alternatives. The product descriptions identify materials and some intended applications, but most do not provide vehicle-specific fitment lists or chain specifications.
That makes checking the manufacturer’s application data and your existing sprocket essential before ordering. The choices below are ranked for general motorcycle relevance, with specialist options placed lower when their compatibility is narrow or less fully documented.
Use the tooth count as a comparison point, not as proof that a sprocket fits your motorcycle.
The JT JTF511.16RB Rubber-Cushioned Front is the leading choice here for riders seeking a motorcycle front sprocket with a stated functional distinction. Its 16-tooth design uses Japanese SCM420 chromoly steel and a rubber cushion described as damping chain impact on the sprocket teeth. The listing also identifies OEM-proven design and heat treatment.
Confirm that its model-specific fitment and tooth count match your motorcycle before buying; those details cannot be established from the product description alone.

Detailed Reviews: Best Sprockets For Motorcycles
#1 · Best Overall
1. JT JTF511.16RB Rubber-Cushioned Front
- Weight: 8.8 oz
- Dimensions: 1.2 x 4.6 x 5.8 in
Best for: Cushioned 16-tooth front sprocket.
Why it ranks #1: Its 16-tooth front design uses Japanese SCM420 chromoly steel and a rubber cushion described as damping chain impact, making its intended function unusually clear.
A rubber cushion that dampens chain impact on the teeth is the distinguishing feature of JT’s 16-tooth front sprocket. It targets riders seeking that cushioning behavior in a countershaft sprocket, while Japanese SCM420 chromoly steel and heat-treated, hand-finished construction address material and manufacturing durability.
The rubber cushioning is intended to dampen chain impact on the front sprocket teeth, a practical distinction for riders prioritizing that feature. Its 16-tooth count narrows the gearing application to setups calling for that count. JT specifies Japanese SCM420 chromoly steel and says the sprocket is heat-treated and hand-finished; the description also states it outlasts mild steel or surface-hardened sprockets. The listing cites OEM-proven technology, but does not specify chain size or motorcycle fitment.
- Rubber cushioning to dampen chain impact
- 16-tooth front countershaft sprocket
- Japanese SCM420 chromoly steel
- Heat-treated and hand-finished
- The 16-tooth count limits use to setups calling for that front gearing.
Skip it if you need a different front tooth count or a chain size and vehicle application explicitly identified in the listing.
This suits riders seeking a cushioned front countershaft sprocket with 16 teeth and Japanese SCM420 chromoly steel. The rubber is intended to damp chain impact, but the fixed count and unspecified fitment details remain important boundaries.

2. JT JTF1321.13 Front
- Weight: 4.6 oz
- Dimensions: 6 x 4.5 x 0.5 in
Best for: Chromoly 13-tooth front sprocket.
Why it ranks #2: This 13-tooth steel front sprocket specifies SCM415 chromoly alloy, heat treatment, and hand finishing; check its application before selecting it.
SCM415 chromoly steel distinguishes JT’s 13-tooth front sprocket, giving riders a steel front replacement with a named alloy rather than an unspecified steel construction. The fixed 13-tooth count makes it relevant to a particular gearing plan, while heat treatment and hand finishing add a stated durability-focused manufacturing process.
As a front sprocket with 13 teeth, this part serves buyers whose replacement plan calls for that count; it cannot itself accommodate a different gearing target. JT specifies SCM415 chromoly steel alloy and describes accurate machining, heat treatment, and hand finishing. Those processes support the stated durability intent and provide useful construction detail for a replacement decision. The listing does not provide a chain size or motorcycle fitment, so the count and material are not enough to verify a complete match.
- 13-tooth front sprocket
- SCM415 chromoly steel alloy
- Heat-treated construction
- Hand-finished and accurately machined
- The fixed 13-tooth count cannot serve a front-gearing plan requiring another count.
Skip it if you need another front tooth count or require a chain size and vehicle application stated by the listing.
This suits a rider seeking a 13-tooth front sprocket in SCM415 chromoly steel and valuing heat-treated, hand-finished construction. Keep the fixed tooth count in mind, and do not treat the listed material as proof of vehicle fit.

3. JT JTR897.49SC Self-Cleaning Rear
- Weight: 1.45 lb
- Dimensions: 5 x 5 x 5 in
Best for: Mud-shedding 49-tooth rear sprocket.
Why it ranks #3: The 49-tooth rear sprocket combines C49 high-carbon steel with self-cleaning grooves described as shedding mud and debris.
Self-cleaning grooves that shed mud and debris distinguish JT’s 49-tooth rear sprocket, making it a relevant steel option for riders whose sprocket operates in dirty conditions. C49 high-carbon steel, heat treatment, and hand finishing add construction details alongside the feature aimed at clearing contamination.
The 49-tooth count defines the gearing this rear sprocket supports, while its self-cleaning grooves are described as quickly shedding mud and debris. That groove feature is especially relevant where material can collect around a sprocket during use. JT specifies C49 high-carbon steel and says the part is heat-treated and hand-finished to meet or exceed OEM standards. The listing does not provide a chain size or motorcycle application, so those details still govern whether this specific rear sprocket fits.
- Self-cleaning grooves shed mud and debris
- 49-tooth rear sprocket
- C49 high-carbon steel
- Heat-treated and hand-finished
- The fixed 49-tooth count excludes rear setups requiring a different gearing choice.
Skip it if you need another rear tooth count or your application requires a chain size stated in the product details.
Choose this for a 49-tooth rear replacement when self-cleaning grooves for shedding mud and debris matter. Its C49 steel construction adds a durability focus, while tooth count and unlisted chain and vehicle fitment remain boundaries.

4. JT JTR269.45 Rear
- Weight: 2 lb
- Dimensions: 7.4 x 7.4 x 5 in
Best for: Steel 45-tooth rear replacement.
Why it ranks #4: Its 45-tooth rear sprocket is made from C49 high-carbon steel and is described as heat-treated and hand-finished.
C49 high-carbon steel is the defining feature of JT’s 45-tooth rear sprocket, offering a steel option for riders replacing a rear sprocket while retaining a 45-tooth gearing choice. Heat treatment and hand finishing add manufacturing steps intended to support durability and meet demanding powersports quality standards.
The 45-tooth count makes this a specific gearing choice rather than a general-purpose adjustable part, so it suits a replacement plan that calls for that count. JT identifies C49 high-carbon steel as its material, while heat treatment and hand finishing support the stated durability focus. Accurate machining, cited in the product description, is relevant to a sprocket’s manufactured dimensions. This is a rear sprocket; the supplied information does not specify chain size or vehicle fitment.
- 45-tooth rear sprocket
- Made from C49 high-carbon steel
- Heat-treated construction
- Hand-finished and accurately machined
- The fixed 45-tooth count limits gearing choice to setups that call for that count.
Skip it if you need a different rear tooth count or a specified chain size; the listing supplies neither as a variable option.
This suits a rider replacing a rear sprocket with a 45-tooth steel part and valuing heat-treated, hand-finished construction. Treat tooth count as a firm boundary, and use the supplied fitment information to establish compatibility before choosing it.

5. JT JTR1842.47 Rear
- Weight: 0.053 oz
- Dimensions: 7.5 x 7.5 x 5 in
Best for: 47-tooth steel rear replacement.
Why it ranks #5: This 47-tooth black rear sprocket uses C49 high-carbon steel and is described as heat-treated and hand-finished; its exact fitment still needs confirmation.
A 47-tooth count paired with C49 high-carbon steel defines this JT rear sprocket, giving riders a specific steel replacement option for a setup that calls for 47 teeth. Its heat-treated and hand-finished construction adds a durability-focused manufacturing approach without changing that fixed gearing choice.
The listed 47 teeth make this most relevant when replacing a rear sprocket with that exact count; it is not a variable-tooth component. C49 high-carbon steel provides the named material, and JT’s description adds accurate machining, heat treatment, and hand finishing. Those processes support the maker’s stated durability goal. The black listing identifies its appearance, but the supplied information does not give a chain size or specific motorcycle fitment, so the tooth count alone cannot establish compatibility.
- 47-tooth rear sprocket
- C49 high-carbon steel construction
- Heat-treated
- Hand-finished and accurately machined
- Its fixed 47-tooth count is unsuitable when the planned rear gearing calls for another count.
Skip it if you require a rear sprocket with a different tooth count or need a chain size stated in the listing.
Choose this for a rear-sprocket replacement requiring 47 teeth and C49 steel construction. It is a poor match for a gearing change calling for another count, and the listing’s tooth count does not establish motorcycle or chain compatibility.

6. JT JTR499.40 Rear
- Weight: 1.5 lb
- Dimensions: 8.5 x 8.5 x 5 in
Best for: 40-tooth high-carbon rear sprocket.
Why it ranks #6: The 40-tooth rear sprocket specifies C49 high-carbon steel, heat treatment, and hand finishing, providing clear construction details for a replacement search.
JT pairs a 40-tooth rear configuration with C49 high-carbon steel, making this a specific replacement choice for riders whose gearing calls for that count. Heat treatment and hand finishing are also stated, adding manufacturing details that support the product’s focus on durability and quality standards.
The 40-tooth count is the central selection constraint: it suits a rear replacement plan calling for 40 teeth, not a different gearing target. C49 high-carbon steel is the named material, and the listing says every sprocket is heat-treated and hand-finished to meet or exceed its quality standards. Together, those construction details provide a durability-oriented steel option. This listing identifies a rear sprocket but does not specify chain size or a motorcycle application, leaving those fitment details unresolved.
- 40-tooth rear sprocket
- C49 high-carbon steel
- Heat-treated construction
- Hand-finished to stated quality standards
- The fixed 40-tooth count limits this part to rear gearing plans requiring 40 teeth.
Skip it if you need a different rear tooth count or depend on a chain size and application specified in the listing.
Consider this JT rear sprocket when your replacement requires 40 teeth and C49 high-carbon steel. The heat-treated, hand-finished construction is relevant to durability-focused buyers, but the listing leaves chain size and vehicle application unspecified.

7. JT JTR1332.44 Rear
- Weight: 0.053 oz
- Dimensions: 9.25 x 9.25 x 5 in
Best for: 44-tooth vehicle-specific rear sprocket.
Why it ranks #7: This 44-tooth C49 steel rear sprocket is listed as vehicle-specific and heat-treated, but the application must be checked against the motorcycle.
A vehicle-specific 44-tooth specification makes this JT rear sprocket a targeted choice rather than a universal gearing part. It uses C49 high-carbon steel and is heat-treated and hand-finished, combining a defined tooth count with construction details intended to meet or exceed OEM standards.
The 44-tooth count gives buyers a precise rear-sprocket replacement target, and the vehicle-specific fit type signals that application matters as well as tooth count. JT names C49 high-carbon steel and says the sprocket is heat-treated and hand-finished to meet or exceed OEM standards. Its description also claims it outlasts mild steel or surface-hardened sprockets. Since the supplied listing does not name the vehicle application or chain size, those details must not be inferred from the tooth count alone.
- 44-tooth rear sprocket
- C49 high-carbon steel
- Heat-treated and hand-finished
- Listed as vehicle-specific
- The 44-tooth vehicle-specific design is unsuitable for applications calling for another fit or count.
Skip it if you need a rear sprocket for a different tooth count or your vehicle application is not the one this part fits.
This is for a buyer replacing a vehicle-specific rear sprocket with a 44-tooth C49 steel part. Its heat-treated, hand-finished construction is relevant, but the supplied listing does not name the application or chain size.

8. JT JTF249.13 Front
- Weight: 2.88 oz
- Dimensions: 4.1 x 3.6 x 5 in
Best for: 13-tooth steel front sprocket.
Why it ranks #8: It is a 13-tooth steel front sprocket from JT, but the supplied listing provides fewer material and construction details than the other JT front options.
A fixed 13-tooth front configuration defines JT’s JTF249.13 steel sprocket, giving riders a specific replacement choice when their gearing plan calls for that count. Its listing identifies a black steel front sprocket, while JT’s manufacturing information describes accurate machining, heat treatment, and hand finishing as part of its sprocket approach.
The 13-tooth count makes this a focused front-sprocket replacement, not a way to choose among gearing ratios. JT’s general product description cites accurate machining, heat treatment, and hand finishing, which provide construction context for buyers evaluating a replacement. The supplied item title identifies steel but does not name a specific steel alloy for this model. No chain size or vehicle application is supplied, so installation compatibility cannot be established from the tooth count alone.
- 13-tooth front sprocket
- Steel construction
- Black finish listed
- JT description cites heat treatment and hand finishing
- The fixed 13-tooth count limits it to front gearing plans requiring that count.
Skip it if you need another front tooth count, a named steel alloy, or a chain size stated for the sprocket.
This fits buyers seeking a black steel front sprocket with 13 teeth for a matching gearing plan. JT cites heat treatment and hand finishing, but the listing does not identify a specific alloy, chain size, or vehicle application.

9. ZTDZZH 53-Tooth Rear
- Weight: 1.87 lb
Best for: 420-chain small-bike rear option.
Why it ranks #9: Its 53-tooth rear design lists a 420 chain and a 76 mm inside diameter for several pit and dirt bike engine sizes, making fitment unusually specific.
The 53-tooth count and stated 420-chain compatibility make this ZTDZZH rear sprocket a specific option for listed small-displacement bikes and ATVs. Its 76 mm inside diameter and 92 mm centre-hole measurement give buyers concrete dimensions to compare with an existing sprocket before planning an installation.
This sprocket is listed for 420 chain and applications including 50CC through 250CC pit and dirt bikes, ATVs, quad bikes, and motorcycles. The 53 teeth define its gearing choice, while the 76 mm inside diameter and 92 mm centre-hole measurement help with dimensional comparison. The listing also gives 8.5 mm screw mounting holes, useful when checking mounting layout. These dimensions support a more informed fit check, but do not establish compatibility with every listed vehicle.
- 53-tooth rear sprocket
- Listed for 420 chain
- 76 mm inside diameter
- 8.5 mm screw mounting holes
- Its 420-chain specification and stated mounting dimensions restrict it to compatible setups.
Skip it if you use a chain other than 420 or need different centre-hole, inside-diameter, or mounting-hole dimensions.
This fits buyers considering a 53-tooth rear sprocket for a 420-chain small bike, ATV, or quad. Compare the 76 mm inside diameter, 92 mm centre hole, and mounting holes with the existing setup before installation.

10. doin al KR5V 10-Tooth Sprocket
- Weight: 2.08 oz
Best for: KR5V V2 electric sprocket.
Why it ranks #10: This alloy 10-tooth sprocket is restricted to the KR5V V2 after April 2025, uses a 420 chain, and is explicitly not for MY1020 motors.
Compatibility with the upgraded KR5V V2 after April 2025 is the key distinction of this 10-tooth, 420-chain sprocket. Its alloy construction receives heat treatment to improve surface hardness and wear resistance, giving owners of the specified electric setup a purpose-specific replacement rather than a general motorcycle sprocket.
The 10-tooth count and 420-chain specification define the transmission pairing this sprocket serves. The listing limits its application to the upgraded KR5V V2 model after April 2025 and expressly excludes the older version and MY1020 motor, making model identification essential before installation. Alloy construction and heat treatment are stated to enhance surface hardness and wear resistance. Precision machining is also cited, supporting dimensional consistency for the intended chain and compatible model.
- 10-tooth sprocket
- For 420 chain
- Specified for upgraded KR5V V2 after April 2025
- Heat-treated alloy with precision machining
- It is not compatible with the older KR5V version or MY1020 motor.
Skip it if you own an older KR5V or MY1020 motor; neither is listed as compatible with this sprocket.
This is for owners of the upgraded KR5V V2 electric motorcycle, ATV, quad, or pit-bike setup who need a 10-tooth 420 sprocket. Its clear boundary is strict: it does not suit the older version or MY1020 motor.

View on AmazonAvoid a chain-and-sprocket mismatch
A chain-and-sprocket mismatch can cause poor engagement or accelerated wear, so verify chain pitch and sprocket compatibility before ordering. Among these listings, the ZTDZZH 53-Tooth Rear explicitly specifies a 420 chain, and the doinal KR5V 10-Tooth Sprocket also identifies a 420 chain. The JT listings supplied here do not state chain size, so do not infer it from tooth count, brand, or material.
Confirm the chain designation on your existing setup and check the vehicle application for the exact part number. Also compare mounting pattern, center opening, and dimensions where available: the ZTDZZH listing gives a 76 mm inside diameter and an approximately 92 mm center-hole measurement, but that information does not establish compatibility with other motorcycles.
Treat a mismatch as a reason to pause and verify, rather than assuming a similar-looking sprocket will work.
Tooth count is not a fitment guarantee
Tooth count alone cannot confirm fitment or predict a precise change in riding behavior; the sprocket must also match the motorcycle, chain, and mounting dimensions. This set spans front sprockets with 10, 13, and 16 teeth and rear options with 40, 44, 45, 47, 49, and 53 teeth. Those numbers make it easy to compare listed options, but the products are not interchangeable just because their counts are close.
The doinal 10-tooth part, for instance, is limited to a specified KR5V V2 version and excludes MY1020 motors. The 53-tooth ZTDZZH rear listing gives measurements and names small dirt-bike engine classes, while several JT products supply part numbers but no application list in the supplied data.
Check the stock tooth counts and manufacturer fitment information before changing gearing or replacing a sprocket.
How to Choose a Motorcycle Sprocket
Front or rear position and fitment
Look first for the correct sprocket position and confirmed vehicle fitment, not just a matching tooth count. This set includes front options from 10 to 16 teeth and rear options from 40 to 53 teeth, but the listings do not supply a complete motorcycle application chart. The ZTDZZH rear gives a 76 mm inside diameter and mounting measurements, while the doinal sprocket is limited to the KR5V V2 after April 2025 and excludes MY1020 motors.
Riders replacing a stock part should match the existing position, part number, mounting dimensions, and manufacturer application. Those with a specialized electric or pit bike should favor the explicitly stated application only when their vehicle matches it exactly; general motorcycle buyers should verify JT fitment independently.
Tooth count and chain specification
Choose a tooth count and chain specification that match your drivetrain and intended gearing, and verify both before purchase. The listed front sprockets have 10, 13, or 16 teeth; rear choices run from 40 through 53 teeth. Only the ZTDZZH 53-Tooth Rear and doinal KR5V 10-Tooth Sprocket explicitly identify a 420 chain in the supplied details.
Do not treat those values as universal for the other products. A rider replacing a worn sprocket without changing gearing should start with the stock tooth count and chain designation.
A buyer considering a different count should first confirm compatibility with the motorcycle and chain, since these listings do not provide enough information to predict the resulting gearing change.
Material and design features
Compare the stated material and special construction only after confirming fitment. Several JT rear options use C49 high-carbon steel, and the JT JTF1321.13 Front specifies SCM415 chromoly alloy; the JT JTF511.16RB Rubber-Cushioned Front specifies Japanese SCM420 chromoly steel and a rubber cushion intended to damp chain impact. The JT JTR897.49SC Self-Cleaning Rear adds grooves described as shedding mud and debris.
The doinal sprocket is alloy with a stated heat-treatment process, while the ZTDZZH listing does not identify its material. Riders prioritizing a stated cushioning feature can consider the rubber-cushioned front option; off-road users may value the self-cleaning grooves.
For a standard replacement, compare the material details but do not let them override correct application and dimensions.
Which Motorcycle Sprocket Should You Choose?
For a front sprocket with a clearly described special function, choose the JT JTF511.16RB Rubber-Cushioned Front, ranked first for its 16 teeth, SCM420 steel, and impact-damping cushion. If you need a steel front option without that feature, compare the JT JTF1321.13 Front and JT JTF249.13 Front only after confirming their application. For an off-road rear where mud shedding matters, consider the JT JTR897.49SC Self-Cleaning Rear.
The JT JTR269.45 Rear, JT JTR1842.47 Rear, JT JTR499.40 Rear, and JT JTR1332.44 Rear offer different listed rear tooth counts in C49 steel. The ZTDZZH 53-Tooth Rear and doinal KR5V 10-Tooth Sprocket are specialist choices; verify their stated chain and vehicle restrictions before purchase.

Frequently Asked Questions
How do I confirm a sprocket fits my motorcycle and chain?
Check the sprocket’s stated fitment against your motorcycle’s exact make, model, and year, then verify front or rear position, tooth count, and chain compatibility. Match these details to your current setup or the manufacturer’s fitment information. If the listing does not establish compatibility, confirm it before ordering rather than relying on appearance alone.
What changes when I alter the front or rear sprocket tooth count?
Changing tooth counts changes the final gearing. A smaller front or larger rear sprocket generally favors acceleration and raises engine speed at a given road speed; a larger front or smaller rear generally favors lower engine speed and higher speed potential. The actual result depends on the motorcycle and setup, so check suitability before changing counts.
When is a rubber-cushioned or self-cleaning sprocket useful?
A rubber-cushioned front sprocket may suit riders seeking reduced chain impact at the sprocket teeth; the listed JT design describes its rubber cushion as damping that impact. A self-cleaning rear sprocket may be useful off-road where mud shedding matters. Neither feature replaces checking fitment, chain compatibility, and tooth count.
How should I choose between a front and rear sprocket?
Choose the position required by your motorcycle and intended replacement; front and rear sprockets are not interchangeable. Compare tooth count and chain compatibility with your current setup, and confirm the listing’s application. If considering a gearing change rather than a like-for-like replacement, check that the proposed combination is appropriate for your motorcycle.
What should I check on specialist sprocket listings?
Verify the stated chain and vehicle restrictions before choosing a specialist option. For example, one listed rear sprocket specifies a 420 chain and a range of small vehicle types, while the 10-tooth listing names KR5V V2 electric motorcycles, ATVs, quads, dirt bikes, and pit bikes. Confirm the exact application rather than assuming broad fitment.
Final Words
Start with your motorcycle’s exact fitment, chain, sprocket position, and required tooth count; the product titles alone do not confirm compatibility. For a front sprocket with a stated functional distinction, the rubber-cushioned JT JTF511.16RB is the leading choice here. Consider the self-cleaning rear for off-road mud shedding, and compare the other steel options by listed tooth count.
Treat the 53-tooth and KR5V 10-tooth listings as specialist choices, verifying restrictions before purchase.
