Keep your FIRSTGEAR Ajax Adventure motorcycle helmet comfortable and hygienic with the FIRSTGEAR Ajax Replacement Interior Liner — Large. Designed as a genuine OEM replacement, this liner restores the exact fit, breathability, and moisture management the Ajax helmet was engineered to deliver.
Helmet liners degrade over time from heat, sweat, and regular use — losing their shape and absorbing odors that degrade comfort. Swapping in a fresh Large liner is a simple, low-cost way to bring your Ajax helmet back to factory condition, ensuring proper fit and consistent protection on every ride.
Simple maintenance, big impact. The FIRSTGEAR Ajax Liner (Large) keeps your adventure helmet fresh, comfortable, and ready for the next ride. Compatible exclusively with the FIRSTGEAR Ajax Adventure helmet series.
