Best Lightweight Modular Motorcycle Helmet: 10 Options Compared

#1 · Best Overall

1. HJC i100 Beis

• Weight: 3.46 lb

Best for: UV-conscious modular rider.

Why it ranks #1: Its listed weight is 3.46 pounds, and it meets DOT FMVSS 218; the Pinlock-ready HJ-36 shield and integrated sun visor add practical features.

The HJC i100's HJ-36 shield combines 99% UV protection with an anti-scratch coating, making its visor specification the central appeal for riders who spend time in daylight. DOT FMVSS 218 compliance and a listed 3.46-pound weight add concrete safety-standard and carrying-weight context.

The HJ-36 shield is Pinlock-ready and provides 99% UV protection, while its anti-scratch coating helps resist surface marks in regular handling. An integrated HJ-V11 sun visor gives riders a separate option for managing bright conditions without changing the main shield. The helmet meets DOT FMVSS 218, and its listed weight is 3.46 pounds. The supplied feature text names optional shield variants as sold separately, so buyers should distinguish those from the integrated sun visor.

Skip it if you need a replacement shield variant included; the listed optional HJ-36 variants are sold separately.

The i100 suits riders who want a modular helmet with an integrated sun visor and a UV-protective, anti-scratch main shield. Consider accessory needs separately, since replacement shield variants are optional.

#2 · Lightweight Pick

2. HJC i91 Solid

• Weight: 3.5 lb
• Material Type: Polycarbonate (PC)
• Compatible with Vehicle Type: Street Bike

Best for: Pinlock-ready street touring.

Why it ranks #2: At a listed 3.5 pounds, it is among the lightest specified helmets here and includes a Pinlock-ready HJ-33 shield with 99% UV protection.

The HJC i91 pairs a Pinlock-ready HJ-33 shield with 99% UV protection, a useful combination for street riders who want a ready-to-configure main visor. Its DOT approval and polycarbonate construction provide clear specification context, while the modular format supports opening the chin section when the riding situation calls for it.

The HJ-33 shield's anti-scratch coating helps protect its surface during ordinary handling, while its 99% UV protection addresses sunlight exposure. Pinlock readiness gives riders an option to add a compatible insert, though the listed optional shields are sold separately. The polycarbonate shell keeps the construction straightforward, and DOT FMVSS 218 compliance identifies its stated U.S. safety standard. The listed configuration is a street-bike modular helmet rather than an adventure-specific model.

Skip it if you need a Pinlock insert or sun visor included; these are listed as optional accessories sold separately.

This is a fit for street riders seeking a DOT-approved modular helmet with a UV-protective, Pinlock-ready shield. Factor optional shield accessories into the setup, since the listed add-ons are not included.

#3 · 180-Degree Flip

3. LS2 Advant X

• Weight: 6 lb
• Material Type: High Performance Fiberglass Composite (HPFC)
• Compatible with Vehicle Type: Motorcycle

Best for: Two-mode modular touring.

Why it ranks #3: Its feature listing gives 1,600g, plus or minus 50g, and describes a 180-degree modular system; note the specifications also list a 6-pound item weight.

The LS2 Advant X carries ECE P and J certification for use as a full-face or open-face helmet, giving riders two approved chin-bar configurations. Its 180-degree modular system is intended to make on-and-off handling easier, while the included Pinlock insert saves a separate accessory step for the compatible shield.

The Advant X uses a 180-degree modular mechanism, allowing the chin bar to move around for open- or full-face use and easier removal. Its P and J certifications correspond to both configurations, giving riders a documented choice in how to wear it. The included Pinlock insert supports the shield's anti-fog setup without a separate insert purchase. Sizing is a practical caveat: the listing says it runs small and advises ordering at least one size larger than the chart suggests.

Skip it if you need a straightforward chart-based fit; the listing says this helmet runs small and advises sizing up.

This suits riders wanting a 180-degree modular helmet with both open- and full-face certification and an included Pinlock insert. Account for its stated small fit when selecting a size.

#4 · Intercom-Ready

4. CYRIL Modular Helmet

• Weight: 1650 g
• Material Type: Acrylonitrile Butadiene Styrene (ABS)…
• Compatible with Vehicle Type: Motorcycle

Best for: Intercom-ready modular rider.

Why it ranks #4: The listing specifies a 3.6-pound design, ABS shell, and intercom compatibility, making it a light-oriented option with connectivity in mind.

Intercom compatibility is the CYRIL A128's clearest practical distinction, giving riders a helmet specified for pairing with communication equipment. Its ABS shell, EPS liner, and listed 3.6-pound lightweight design add concrete construction details, while the tool-free quick-release system supports simpler removal and accessory changes.

The ABS shell and energy-absorbing EPS liner identify the helmet's listed shell and interior materials, while the 3.6-pound design provides a stated weight for riders comparing carry and wear considerations. Intercom compatibility supports a communication setup, and the tool-free quick-release system avoids a tool-based release process. The listing also describes a three-visor system for all-weather use, but the supplied feature text does not identify the individual visor types, so buyers should check those details before relying on a specific configuration.

Skip it if you need clearly identified visor types before choosing; the listing does not detail the three visors.

This suits riders prioritizing intercom compatibility, a stated 3.6-pound weight, and tool-free quick release in a modular helmet. The visor details are a boundary: confirm the three-visor configuration meets your needs.

#5 · Built-In Comms

5. Sena OUTRUSH 2

• Weight: 4 lb
• Material Type: Polycarbonate (PC)
• Compatible with Vehicle Type: Motorcycle

Best for: Connected group-ride helmet.

Why it ranks #5: Listed at 4 pounds, it adds Bluetooth connectivity, Mesh Intercom 3.0, and WAVE Intercom compatibility for riders who prioritize communication.

Built-in Mesh Intercom 3.0 and WAVE Intercom compatibility make the Sena OUTRUSH 2 a communication-focused modular helmet, connecting riders within a group and across compatible brands. Bluetooth smartphone connectivity and second-generation high-definition speakers add phone and audio functions without requiring a separate headset installation.

Mesh Intercom 3.0 supports communication with other riders in a group, while WAVE Intercom compatibility extends communication to other brands' motorcycle headsets within cellular network coverage. Bluetooth smartphone connectivity and the integrated high-definition speakers add phone and music functions within the helmet. The polycarbonate model is listed at 4 pounds and includes a USB-C charging cable. These integrated electronic features serve connected riders, but add functions that buyers seeking a simpler helmet may not need.

Skip it if you ride where cellular coverage is unavailable and need WAVE Intercom's extended communication range.

This is for riders prioritizing integrated group communication, smartphone Bluetooth, and helmet speakers. WAVE Intercom's extended range is bounded by cellular coverage, so consider the route and connection needs.

#6

6. BELL SRT-Modular

• Weight: 4.8 lb

Best for: Prescription eyewear compatible.

Why it ranks #6: Its listed weight is 4.8 pounds; eyewear arm pockets and a Panovision shield with Class 1 optics distinguish it from simpler options.

Woven eyewear-arm pockets in the Bell SRT-Modular liner let riders wear prescription glasses or preferred shades inside the helmet. Its Panovision shield uses Class 1 optics, a specific visibility feature for riders who value a clear view when tucked or checking traffic, and the helmet meets DOT and ECE 22.06 standards.

The liner's eyewear-arm pockets accommodate glasses, addressing a common fit concern for riders who need prescription lenses or choose to ride in shades. The Panovision shield's Class 1 optics support visibility in a tucked position and during lane changes or head checks, as stated in the listing. DOT FMVSS 218 and ECE 22.06 compliance provide the listed standards context. The product information does not provide a helmet weight, so weight-focused comparisons cannot be made from the supplied specifications.

Skip it if you need a listed weight to compare lightweight options; this product's supplied specifications give no weight.

This fits riders who wear prescription glasses or shades and want Class 1 shield optics for street visibility. Weight-conscious shoppers should note that the supplied product details do not state its weight.

#7

7. LS2 Strobe II

• Weight: 5 lb

Best for: Sun-shield daily rider.

Why it ranks #7: The listed weight is 5 pounds, with a built-in drop-down sun shield, quick-release chin strap, and DOT approval.

The LS2 Strobe II integrates a drop-down sun shield, giving riders a built-in option for changing light without swapping the main shield. Its KPA shell and quick-release chin strap add practical details for daily use, while the helmet meets DOT FMVSS 218 and ECE 22.06 rotational energy management requirements.

The built-in drop-down sun shield lets a rider respond to brighter conditions without carrying or installing a separate sun visor. The quick-release chin strap makes fastening and removal more direct at stops. LS2's Kinetic Polymer Alloy shell is described as offering energy-managing flexibility, and the helmet meets DOT FMVSS 218. Its shield is Pinlock-ready, but the Pinlock insert is sold separately, a relevant consideration for riders planning their anti-fog setup.

Skip it if you want a Pinlock insert included with the helmet; the LS2 Advant X includes one.

The Strobe II fits riders who value a built-in sun shield and quick-release strap for everyday stops. Choose with the separate Pinlock purchase in mind if an insert is part of your planned shield setup.

#8

8. ILM Model 902

• Weight: 2.31 kg
• Material Type: Acrylonitrile Butadiene Styrene (ABS)
• Compatible with Vehicle Type: All of the above

Best for: Washable commuter modular.

Why it ranks #8: Its 2.31 kg listed weight is heavier than the lightest picks, but it offers a removable washable liner and a flip-up design.

A removable, washable liner and cheek pads make the ILM 902 practical for riders who want to refresh the helmet interior between rides. Its flip-up chin bar adds a convenient way to open the front without taking the helmet off, while the adjustable quick-release strap supports easier removal.

The ABS shell pairs with a micrometrically adjustable strap, letting riders fine-tune the closure rather than rely on a fixed adjustment. The removable, washable liner and cheek pads simplify routine interior care, and the modular flip-up function makes it easier to open the front during a stop. A wide-view, anti-scratch clear visor supports forward visibility; note that the standard visor does not have anti-fog functionality, despite the feature listing's anti-fog wording.

Skip it if you need anti-fog performance from the included visor; the standard clear visor does not provide it.

This suits commuters seeking a modular helmet with washable interior parts and quick-release fastening. Its standard visor is the key boundary: riders who require anti-fog functionality will need a different visor solution.

#9

9. ScorpionEXO AT960

• Weight: 5.8 lb
• Material Type: Polycarbonate (PC)
• Compatible with Vehicle Type: Adventure

Best for: Adventure modular touring.

Why it ranks #9: At 5.8 pounds, it is comparatively heavy; its adventure focus, removable peak, and DOT FMVSS 218 certification suit a different priority.

The ScorpionEXO AT960 lets riders remove its peak for cleaner touring aerodynamics or keep it for adventure riding, making its configuration adaptable to the route. Its P/J dual homologation also permits use with the chin bar open or closed, while CAD-refined aerodynamics target reduced lift and turbulence.

The removable peak supports two practical setups: retain it for ADV use or remove it for a cleaner touring profile. P/J dual homologation covers open-chin Jet and closed-chin Full configurations, so riders can choose between those modes. CAD-refined aerodynamics are specified to minimize lift and turbulence, and channels in the multi-layer EPS provide airflow. The aero-tuned vents and dual-position mouth vent add ventilation and defogging options, with the mouth vent adjustable from inside.

Skip it if you prioritize a lower stated helmet weight; this model is listed at 5.8 pounds.

The AT960 suits adventure riders who want a removable peak, open- or closed-chin homologation, and adjustable ventilation. Its listed 5.8-pound weight is an important boundary for weight-focused buyers.

#10

10. LS2 Valiant II

• Weight: 6 lb
• Material Type: Kinetic Polymer Alloy (KPA)
• Compatible with Vehicle Type: Motorcycle

Best for: 180-degree flip-up modular.

Why it ranks #10: The listed weight is 6 pounds, making it a poor match for weight-first shopping, though its 180-degree flip design remains distinctive.

The LS2 Valiant II's 180-degree flip mechanism lets its chin bar rotate around, enabling a distinctive open-face configuration from a modular helmet. Its redesigned, smaller and slimmer chin-bar mechanism is described as producing a more aerodynamic shell, while the KPA construction and DOT FMVSS 218 compliance round out the core specifications.

The 180-degree chin-bar rotation is the practical centerpiece, giving riders an open-face option without removing the modular assembly. LS2 says the redesigned mechanism is smaller and slimmer than the original Valiant and makes the shell more aerodynamic. The Kinetic Polymer Alloy material identifies the shell construction, while DOT FMVSS 218 compliance supplies the listed U.S. safety standard. At a stated 6 pounds, it is a relatively weight-conscious buyer's consideration when comparing modular designs.

Skip it if you prioritize a lower stated helmet weight; the Valiant II is listed at 6 pounds.

The Valiant II suits riders seeking a 180-degree modular system for switching to an open-face configuration. Its listed 6-pound weight is a relevant boundary for shoppers focused on minimizing helmet weight.
