Brand: Bell Racing
This special front spoiler has been developed to combat lift by creating downforce on the front of the helmet. It attaches to the chin bar just below the face shield using double-stick tape (provided). The tape is designed to hold firmly at speed, yet remove without taking paint with it. Fits the SA2010 Bell Star GP Helmet (Part No. BE001-S10) and the SA2010 Bell GP.2 Helmet (Part No. 2362-S10) only.
Medium works well at speeds above 150mph.
Large is effective at speeds below 150mph.
Because of the way air behaves at different speeds, Bell offers two different sizes.
