The Bell Helmet Top Gurney (also known as a wicker bill) is designed to combat helmet lift and buffeting at speed. It attaches near the top of the helmet to separate airflow as it comes over the helmet. This eliminates the low-pressure area behind the helmet that causes lift and buffeting. It is recommended for use in any type of open cars or karts. This Gurney flap is designed to fit any Bell helmet with a smooth shell, but it could be adapted to other brands with a little work. Clear plastic lets your custom paint show through. Adheres with double-stick tape (provided).
Small is most effective at speeds above 180mph.
Medium works well at speeds between 150 and 180mph.
Large is effective at speeds below 150mph.
Because of the way air behaves at different speeds, Bell has developed three different sizes.
Note: The Top Gurney is not designed for use with a helmet spoiler. We also offer the Bell Wicker for Helmet Spoiler (Part No. BE206), which is designed for attachment on a rear helmet spoiler.
