Scooter Helmet Liner Replacement for 3/4 Shield Helmets

Replacement Liner for 3/4 Shield Helmets

This spare liner is made for 3/4 shield helmets and offers an affordable way to bring back comfort and a snug fit. Liners tend to flatten and lose their shape with regular use, which can make a ride feel less comfortable. Fitting a new one restores that fresh feel. It's one of the easiest scooter helmets & riding gear upgrades you can do at home, helping keep your helmet comfortable and working as it should.

Compatibility and Fit Adjustment

This liner only works with 3/4 shield helmets, so it isn't suitable for 1/2 helmets or 3/4 open face helmets. You can swap liners freely within the same shell size group to fine-tune the fit to your liking. Shell 1 covers sizes XS, S, and M, while Shell 2 covers sizes L, XL, and XXL.

When to Replace Your Liner

Consider replacing your helmet liner once comfort or fit starts to slip. Worn liners can stop offering the same support, which may change how the helmet feels while you ride. Refreshing the liner regularly is a quick, low-cost way to keep your helmet in good condition.
