FAQ
Is the K.1 Pro only for open-wheel racing?
No — it's built as a multi-use helmet, with open-wheel racers specifically in mind, but it works across racing types.
What's the appeal of this helmet?
It's Bell's budget-priced SA2020 option — certification without the price tag of the pro-level shells.
FastLap Supply Take: If you want SA2020 certification without paying for Bell's top-tier carbon shells, the K.1 Pro is the honest starting point.

Actually Measuring Your Head
Use a soft measuring tape (craft store, like $3). Wrap it around the widest part of your dome, forehead to back, and get the same number twice. Use that number to pick your size. Revolutionary, we know. lol.
