A strong 21-inch motorcycle tire should match your motorcycle’s specified size and load requirements while suiting the way you ride; this selection focuses on cruiser and touring front tires. The Shinko SR777 HD Black Wall is the leading all-round choice in this group, with a 120/70-21 size, reinforced carcass, and 695-pound listed load capacity. Other options cover 80/90-21 and MH90-21 fitments, whitewall styling, and different riding priorities, including touring and wet-weather grip.
Compare the exact size printed on your current tire with your owner’s manual before choosing: a 21-inch rim alone does not make different tire widths or profiles interchangeable. The rankings weigh the listed fitment and specifications first, then use-case details and supplied product information.
The Shinko SR777 HD Black Wall is the best overall choice in this lineup for riders whose motorcycle calls for a 120/70-21 front tire. Its listed 695-pound load capacity, heavy-duty reinforced carcass, and tread siping and grooves for wet and dry conditions make it a well-rounded cruiser option. It is not a universal fit: confirm that 120/70-21 matches your motorcycle’s requirements.
Riders seeking an 80/90-21 or MH90-21 should compare the correctly sized alternatives instead.

Detailed Reviews: Best 21 Inch Motorcycle Tire

#1 · Best Overall
1. Shinko SR777 HD Black Wall
- Size: 120/70-21
- Rim Size: 21 in
- Load Capacity: 695 lb
- Weight: 13.5 lb
Best for: Heavy-duty cruiser front.
Why it ranks #1: Its 120/70-21 fitment, 695-pound listed load capacity, and reinforced heavy-duty carcass suit cruiser riders seeking a substantial front-tire option.
Its reinforced heavy-duty carcass is the defining feature, giving cruiser riders a more stable front-tire foundation in the 120/70-21 size. Shinko pairs that construction with a grip-focused rubber compound and functional tread siping, making this black-wall bias tire a practical option for V-Twin and metric cruiser setups seeking wet- and dry-road traction.
The 120/70-21 fit and 21-inch rim specification identify this as a front tire for compatible cruiser wheels, while the reinforced carcass is intended to provide a more stable feel. Functional siping and grooves support traction in both wet and dry conditions, and the compound is formulated for grip and comfort. Shinko also highlights traction during acceleration, braking, and cornering, so the tread and rubber choices address several everyday riding demands rather than appearance alone.
- Heavy-duty reinforced carcass for a more stable feel
- Siped, grooved tread supports wet- and dry-road traction
- Rubber compound formulated for grip and comfort
- 695-pound listed load capacity
- Black-wall finish lacks the whitewall styling some cruiser builds call for.
Skip it if you want a whitewall look; this Shinko is specified as a black-wall tire.
Choose it if your cruiser takes a 120/70-21 front tire and you value reinforced construction with functional wet- and dry-road tread. Its black-wall finish and specified front fit are important boundaries for styling and wheel compatibility.

- Size: 120/70-21
- Rim Size: 21 in
- Load Capacity: 584 lb
- Weight: 13 lb
Best for: Japanese cruiser all-rounder.
Why it ranks #2: The 120/70-21 size and 584-pound load capacity suit that fitment; the listing describes it as a tubeless tire for Japanese cruisers.
Its unidirectional tread pattern is the Bridgestone Exedra G721’s concrete all-weather feature, specified for reliable performance on dry and wet surfaces.

The description also names long mileage, stability, crisp handling, and riding comfort, giving cruiser riders several stated priorities in one option. Its tubeless construction and 584-pound listed load capacity are additional setup details to consider when matching the tire to the motorcycle.
- Unidirectional pattern for wet- and dry-surface performance
- Bias-ply construction
- Tubeless designation
- 584-pound listed load capacity
- Primarily intended for Japanese cruisers, limiting its stated target use.
Skip it if you ride outside the Japanese-cruiser use this Bridgestone primarily targets; its description focuses on those motorcycles.

#3 · Touring Focus
3. Michelin Commander III Touring
- Size: MH90-21 (54H) Touring Front
- Rim Size: 21 in
- Load Capacity: 467 lb
- Weight: 11.5 lb
Best for: V-twin touring in wet weather.
Why it ranks #3: Its MH90-21 (54H) touring-front fitment and 467-pound capacity target touring motorcycles, while the description highlights wet grip and longevity.
Enhanced wet grip is the Commander III Touring’s defining riding benefit, making it a consideration for V-twin cruiser and touring riders facing changing conditions. Michelin pairs that claim with exceptional longevity and a highly dense, rigid casing intended to support feedback and handling, while the MH90-21 front specification sets a specific fit requirement.
The MH90-21 designation, also listed as 90/90-21 front, helps identify the wheel fit this tire requires. Michelin says its highly dense, rigid casing helps deliver feedback and handling, while the product description highlights enhanced wet grip and exceptional longevity. Those features address both control and service-life priorities for touring use. The line’s velvet sidewall styling and distinctive tread patterns add a visual consideration, but the listed 467-pound load capacity and front size remain important compatibility checks.
- Enhanced wet grip highlighted by Michelin
- Highly dense, rigid casing supports feedback and handling
- Exceptional longevity stated in the description
- Velvet sidewall styling for V-twin appearance
- Listed load capacity is 467 pounds, which may not meet every motorcycle’s load requirement.
Skip it if you need a front tire with a listed capacity above 467 pounds; this Commander III is rated for 467.
This fits V-twin cruiser and touring riders whose front wheel calls for MH90-21 and who prioritize wet grip, handling feedback, and longevity. Check the 467-pound listed capacity and specified size against your motorcycle before deciding.

4. Pirelli Night Dragon
- Size: 90/90-21

Best for: Fast cruiser front fit.
Why it ranks #4: This 90/90-21 M/C 54H TL front tire has a 467-pound listed capacity; supplied facts describe grip for acceleration and control.
Pirelli positions the Night Dragon for riders seeking speed with control, and its verified description highlights strong grip for quick acceleration and cornering.

Its tubeless designation is relevant to the wheel setup, while the 467-pound listed capacity is a concrete load consideration.

- Listed load capacity is 467 pounds, which sets a limit for load planning.

- Size: MH90-21

- Weight: 0.27 g
Best for: Harley touring whitewall front.
Why it ranks #5: The MH90-21 whitewall is engineered and tested with Harley-Davidson; its three-ply polyester casing and two fiberglass belts are listed for touring stability.
A three-ply polyester casing reinforced by two fiberglass belts gives the Dunlop D402 a specific stability feature for touring riders. Engineered and tested with Harley-Davidson, this tubeless MH90-21 whitewall front tire also uses an offset center groove intended to build confidence over rain grooves and steel-grated bridges.
The MH90-21 size identifies the front-tire fit, and the tubeless construction matters when checking the wheel setup. Dunlop’s three-ply polyester casing and two fiberglass belts are specified to help provide stability for touring riding. Its computer-optimized tread profile uses an offset center groove to improve confidence on rain grooves and steel-grated bridges, while also helping reduce cupping for enhanced wear. The medium whitewall appearance suits riders considering classic touring styling, with the 467-pound capacity a separate load check.
- Engineered and tested with Harley-Davidson

6. Shinko 777 White Wall
- Size: 120/70-21
- Rim Size: 21 in
- Load Capacity: 695 lb
Best for: Whitewall cruiser styling.
Why it ranks #6: This 120/70-21 tubeless front tire has a 695-pound listed capacity, H speed rating, and whitewall styling for cruiser applications.
A whitewall sidewall gives this Shinko 777 a clear styling identity, while its 120/70-21 size targets compatible cruiser and custom-frame front wheels. Shinko also specifies a tubeless, four-ply construction and a grip-focused compound, combining the visual treatment with features relevant to everyday cruiser use.
The 120/70-21 size and 695-pound load capacity are useful checks for a compatible front-wheel application. Its tubeless designation and four-ply construction describe the tire’s setup, while Shinko says the compound is formulated for improved grip. The front-tire profile is described as supporting smooth, neutral steering, a practical consideration for riders who prefer predictable steering response. The whitewall appearance is especially relevant to custom builds, but the motorcycle’s required size and load needs remain the deciding fit factors.
- Whitewall styling
- Tubeless construction
- Four-ply specification
- Smooth, neutral steering profile stated for the front tire
- Its whitewall finish may not suit riders seeking a black-wall appearance.
Skip it if you want a black-wall front tire; this Shinko 777 is specified with whitewall styling.
Choose this for a compatible 120/70-21 cruiser or custom-frame front wheel when whitewall styling and a neutral steering profile are priorities. Its tubeless construction and 695-pound listed capacity are useful fit details, not substitutes for the motorcycle’s requirements.

7. Michelin Commander II
- Size: 80/90-21 (54H)
- Rim Size: 21 in
- Load Capacity: 1000 lb
- Weight: 2.7 kg
Best for: Long-mileage cruiser touring.
Why it ranks #7: Its 80/90-21 (54H) cruiser-front fitment carries a listed 1,000-pound capacity, and the description emphasizes stable handling and long mileage.
Michelin’s Amplified Density Technology is the key handling feature, with the Commander II described as stable and responsive for cruiser riding. This 80/90-21 front tire also pairs an easy-steering profile with a comfortable highway ride, giving riders who prioritize touring composure a tire choice with a distinctive custom-oriented appearance.
The 80/90-21 size and 21-inch rim specification make fit the first consideration for a front-wheel replacement. Michelin’s easy-steering profile is paired with claims of precise steering and stable, responsive handling, which can support a composed feel on highway rides. The product description also emphasizes longevity, while Amplified Density Technology is named as part of the handling approach. Together, those details suit riders weighing steering character and extended-distance use, rather than simply matching a visual style.
- Easy-steering profile
- Described as stable and responsive in handling
- Comfortable highway ride highlighted in the description
- 1000-pound listed load capacity
- The specified 80/90-21 front size is narrower than 120/70-21 options.

This suits cruiser riders whose motorcycle calls for an 80/90-21 front tire and who value easy steering on highway trips. Check that size requirement against your wheel before choosing; its touring-oriented ride claims do not change the specified fit.

8. Kenda Kruz K673
- Size: 80/90H-21 (Front)
- Rim Size: 21 in
- Load Capacity: 397 lb
- Weight: 9.4 lb
Best for: All-weather cruiser commuting.
Why it ranks #8: The 80/90H-21 front tire is DOT approved and H-rated to 130 mph; deep, wide grooves are listed for all-weather cruising.
Deep, wide tread grooves are the Kenda Kruz’s clearest practical feature, supporting all-weather cruising traction on this 80/90H-21 front tire. Its new rubber compound is also described as improving straight-line stability and cornering, making it a street-focused option for cruiser riders seeking predictable handling alongside a DOT-approved, H-rated specification.
Kenda’s 3+2 casting design is intended to improve handling and high-load carrying capacity, while its deep, wide grooves target traction for all-weather cruising. The new rubber compound adds a stated benefit for straight-line stability and cornering performance. At 80/90H-21, this is a front tire for a compatible 21-inch rim; its H rating is listed up to 130 mph. The tubeless designation is also relevant when checking the tire against the motorcycle’s wheel setup.
- DOT approved and H-rated up to 130 mph
- Deep, wide grooves for all-weather cruising
- 3+2 casting design aimed at handling and load capacity
- Compound formulated for straight-line stability and cornering
- Listed load capacity is 397 pounds, lower than several other tires in this roundup.

9. Dunlop D404 Front
- Size: 80/90-21
- Rim Size: 21 in
- Load Capacity: 48 hundredths lb
- Weight: 7 lb
Best for: Classic cruiser replacement.
Why it ranks #9: This 80/90-21 front tire is listed for cruisers and a wide range of older bikes, with a tread compound balancing mileage and grip.
A tread compound balancing mileage and grip is the Dunlop D404’s central practical appeal for cruiser riders. This 80/90-21 black-wall front tire is also part of an expanded size range intended to fit older bikes and cruisers, making it a straightforward candidate when that specific 21-inch front size matches the motorcycle.
The 80/90-21 specification and 21-inch rim size establish the fit requirement for this front tire. Dunlop says the expanded size range serves a variety of older bikes and cruisers, while the tread compound aims to balance mileage with grip. That combination is relevant to riders who want a conventional cruiser replacement without choosing between those two stated priorities. The listing also identifies the Kawasaki Vulcan Custom VN900 from 2006–2016 in the title, though the tire size remains the key check for any motorcycle.
- Tread compound balances mileage and grip
- Expanded size range targets older bikes and cruisers
- 80/90-21 front size for a 21-inch rim
- Black-wall appearance
- Its 80/90-21 size is not the 120/70-21 format used by some front-wheel setups.
Skip it if you need a 120/70-21 front tire; this D404 is specified as 80/90-21.
The D404 fits the decision for cruiser owners seeking an 80/90-21 front tire with a mileage-and-grip balance. Its black-wall styling and listed size define the choice; verify the motorcycle’s required tire specification before ordering.

10. Shinko 120/70-21 White Wall Upgrade
- Size: 120/70-21
- Rim Size: 21 in
- Load Capacity: 695 lb
Best for: Long-distance whitewall cruising.
Why it ranks #10: The 120/70-21 reinforced front tire lists a 695-pound capacity and wet- and dry-traction grooves, but its listing is less specific about model fitment.
Elevated tread depth is the Shinko’s clearest long-distance feature, intended to extend wear for riders covering cross-country miles. Its 120/70-21 whitewall front tire also combines a silica-rich compound, functional siping, and deep grooves, supporting the stated aim of grip in wet and dry conditions with a classic cruiser appearance.
The reinforced carcass is described as providing a stable, planted road feel, while the silica-rich compound targets traction in wet and cold weather. Functional siping and deep grooves are specified for wet- and dry-condition traction, and elevated tread depth is aimed at extended wear. Those features make this a touring-minded choice for compatible 120/70-21 front wheels. The whitewall sidewalls deliver the classic cruiser look called out in the description, with a 695-pound listed load capacity to consider for fit.
- Elevated tread depth intended for extended wear
- Silica-rich compound targets wet- and cold-weather traction
- Siping and deep grooves support wet- and dry-road grip
- Reinforced carcass for a stable, planted feel
- Whitewall styling is a poor match for riders seeking a black-wall tire.
Skip it if you prefer black-wall styling; this Shinko is a whitewall 120/70-21 front tire.
Pick this for long-distance cruiser riding when a 120/70-21 front fit, whitewall styling, and tread features aimed at extended wear suit your priorities. Its 695-pound listed capacity and whitewall appearance are key boundaries to weigh.

View on AmazonThe 21-inch rim does not settle fitment
A 21-inch rim measurement alone is not enough to confirm that a tire fits your motorcycle. This lineup includes 80/90-21, 90/90-21, 120/70-21, and MH90-21 listings, so the tires differ in width and profile as well as their size labels. For example, the Shinko SR777 HD Black Wall is listed as 120/70-21, while the Dunlop D404 Front is 80/90-21 and the Michelin Commander III Touring is MH90-21.
Do not treat those as interchangeable based only on the shared rim diameter. Check the motorcycle manufacturer’s specified size and the tire’s front or rear designation, then verify any alternate sizing against approved fitment information.
Also compare the load and speed requirements: listings here include different load capacities and ratings. A mismatch can mean the tire is unsuitable even if the rim diameter appears correct.
Whitewall styling narrows the comparison
Whitewall options in this set combine a styling choice with different sizes and constructions, so compare them by fitment rather than appearance alone. The Shinko 777 White Wall is a 120/70-21 tubeless front tire with a stated 695-pound load capacity and H speed rating. The Shinko 120/70-21 White Wall Upgrade also lists a 695-pound capacity and reinforced construction, while the Dunlop Harley-Davidson D402 Whitewall is an MH90-21 touring tire with a 467-pound capacity and a three-ply polyester casing with two fiberglass belts.
These details make the whitewalls distinct choices, not equivalent alternatives. A common selection failure is choosing a sidewall style first and overlooking the motorcycle’s required size or load rating.
Start with the fitment requirement; then choose between blackwall and whitewall options that meet it.
How to Choose a 21-Inch Motorcycle Tire
Exact tire size
Start by matching the complete tire size specified for your motorcycle, not just the 21-inch rim. The products here span 80/90-21, 90/90-21, 120/70-21, and MH90-21 listings. For instance, the Dunlop D404 Front is 80/90-21, while the Shinko SR777 HD Black Wall is 120/70-21 and the Michelin Commander III Touring is MH90-21.
These formats reflect meaningful differences in fitment, so do not assume that a tire with the same rim diameter is automatically suitable. Riders replacing an existing tire should check its sidewall marking and the owner’s manual; a buyer choosing between models should favor the size explicitly specified for the motorcycle.
Where the specification differs, verify an approved alternative before ordering.
Load and speed requirements
Choose a tire whose listed load and speed specifications meet your motorcycle manufacturer’s requirements. Listed capacities range from 397 pounds for the Kenda Kruz K673 to 1,000 pounds for the Michelin Commander II; many other options list 467, 584, or 695 pounds. Speed information also varies: the Kenda is H-rated to 130 mph, and the Shinko 777 White Wall lists an H rating.
These figures are product-listing details, not a reason to exceed your motorcycle’s specified limits. Riders carrying heavier loads should pay particular attention to the required capacity, while those comparing tires with similar fitment should check the required speed rating as well.
Confirm both requirements in the motorcycle documentation before deciding.
Construction and riding purpose
Match the tire’s construction and stated riding focus to your bike and typical use. The Shinko SR777 HD Black Wall has a reinforced heavy-duty carcass and is designed for cruisers; the Bridgestone Exedra G721 is described as a tubeless bias-ply tire primarily for Japanese cruisers. For touring, the Michelin Commander III Touring is an MH90-21 front option whose description highlights wet grip and longevity, while the Dunlop Harley-Davidson D402 lists a three-ply polyester casing and two fiberglass belts.
These are different product attributes, not a universal ranking of construction types. A cruiser owner seeking reinforcement may prefer the Shinko when its size fits; a touring rider may give more weight to the touring-focused Michelin or Dunlop.
First confirm fitment, then use the intended riding focus to break ties.
Which 21-inch motorcycle tire should I choose?
Choose the Shinko SR777 HD Black Wall if your motorcycle specifies 120/70-21 and you want a reinforced cruiser front tire with a listed 695-pound capacity. For a 120/70-21 Japanese cruiser, consider the Bridgestone Exedra G721, listed as tubeless with a 584-pound capacity. Touring riders with an MH90-21 requirement can compare the Michelin Commander III Touring and Dunlop Harley-Davidson D402 Whitewall; the latter adds whitewall styling and lists a three-ply casing with fiberglass belts.
If your required size is 80/90-21, compare the Michelin Commander II, Kenda Kruz K673, and Dunlop D404 Front by their listed capacities and features. For 90/90-21, the Pirelli Night Dragon is the matching listed option.
Always verify your motorcycle’s specified size and ratings before buying.
Frequently Asked Questions
How do I confirm whether a 21-inch tire fits my motorcycle?
Check your motorcycle’s owner’s manual or the vehicle tire-information label for the required tire size, load rating, and speed rating. Match those requirements to the tire listing, including its front or rear designation. Also confirm tube or tubeless compatibility, and ask a qualified tire professional if the specifications are unclear.
Can I replace an MH90-21 tire with a 90/90-21 tire?
Do not assume these sizes are interchangeable. Confirm the replacement size against your motorcycle manufacturer’s specifications and check the required load and speed ratings. The listed options include MH90-21 touring tires and a 90/90-21 front tire, but the listings alone do not establish that one size is an approved substitute for the other.
What tire pressure should I use for a 21-inch motorcycle tire?
Use the cold tire pressure specified by your motorcycle manufacturer, typically found in the owner’s manual or on the vehicle’s tire-information label. Do not choose pressure based only on the tire’s size or sidewall maximum. Check pressure before riding, and follow the manufacturer’s guidance when carrying a passenger or cargo.
How should I compare load and speed ratings?
Start with the minimum ratings specified for your motorcycle and do not select a tire below them. Compare the listed markings and capacities where provided; for example, the Shinko SR777 HD lists a 695-pound capacity, while the Bridgestone Exedra G721 lists 584 pounds. Verify the complete rating requirements before purchase.
Should I choose a whitewall or black-wall tire?
Choose based on the appearance you want and the exact size your motorcycle requires. This lineup includes whitewall options in 120/70-21 and MH90-21 sizes, as well as black-wall choices in several listed sizes. Styling does not replace fitment checks: confirm the specified tire size and ratings first.
Final Words
Choose by your motorcycle’s specified size and ratings, not by appearance alone. For a required 120/70-21 front tire, the Shinko SR777 HD is the lineup’s best overall choice; the Bridgestone is another listed 120/70-21 option. MH90-21 riders can compare the touring and whitewall choices, while 80/90-21 and 90/90-21 riders should focus on their matching listings.
Verify fitment, load, speed, and tube requirements before ordering.
