Helmet Spare Parts
Helmet spare parts keep a still-good helmet alive, without replacing it. Here you'll find cheek pads, inner linings, visor mechanisms, fastening screws, air vents, safety hooks, and small spare parts for the brands in our catalog: Airoh, Kappa, SMK, HJC, Bayard, Momo Design. A new cheek pad can help re-calibrate the fit of a loose helmet.
Helmet Spare Parts: guide, tips, and frequently asked questions
Strengths
- Cheek pads of various sizes – you can correct a loose fit by just changing the padding
- Washable inner linings – replaceable when the original padding is worn out
- Visor mechanisms – the part that breaks most often after a few years
- Screws and small parts – an economical replacement so you don't have to throw away the helmet
Important notes
- Spare parts are model-specific: a KV40 cheek pad won't fit a KV20.
- If the lining and cheek pads are permanently compressed, it's a sign that the outer polystyrene is also worn: consider a new helmet.
- Do not wash cheek pads in a washing machine: use lukewarm water and neutral soap by hand.
When a spare part is worthwhile
- Helmet moves on your head — Cheek pads one size thicker
- Flattened padding — Complete inner lining
- Visor rattles — Visor mechanism
- Damaged strap — Replacement micrometric closure
Perfect for whom
For those who want to extend the life of a helmet that is less than 5 years old and has a sound shell but worn interior. This is also the section where you'll find the small piece that broke due to repeated use — the peak screw, the hook, the visor release mechanism. Contact us for more information with the brand, model, and name of the part.

Frequently asked questions
Can I tighten the fit by changing the cheek pads?
Yes, that's the classic solution. If the helmet wobbles in turns or on your head, order cheek pads one size thicker for the same model. If it's too tight, use thinner cheek pads. It's often cheaper than buying a new helmet, and the fit returns to being correct.
Can the inner lining be washed?
Yes, but only by hand with lukewarm water and neutral soap (never in a washing machine, never with aggressive detergents). Remove the lining from the helmet according to the manual's diagram, wash, rinse, and let it dry in the shade. Only change the lining if it remains compressed and doesn't regain thickness after washing.
Do visor mechanisms have a limited lifespan?
Yes, they are the most stressed part of the helmet. With 3-5 years of daily use, springs and pawls wear out, the visor starts to rattle or doesn't close cleanly. Replacing the mechanism is economical and restores precision to the helmet without having to replace it.
