The Bell chin bar gurney can be added to many popular Bell helmet models to offer increased downforce on the front of the helmet, which reduces the lift effect and counteracts drag. It can be used on helmets with or without a duckbill. Specifically designed for the HP7, the Bell chin bar gurney can also be used on the RS7 Ultra Lite, RS7 Ultra, RS7 Pro, RS7-K Ultra, RS7-K, KC7-CMR Carbon, and KC7-CMR helmets. Clear plastic is ready for paint and attaches with strong double-sided adhesive. Available in M (8mm), L (13mm), and XL (17mm).
