White Brothers™ didn’t hold anything back in developing a performance exhaust line for the mini riders from 50cc to 230cc. Each R4 exhaust system was developed and tested just like its big brothers to deliver increased performance over stock. Designed to be used either at the track or on the trail. The R4 system is the official exhaust system of the Red Rider Junior Super Moto Challenge on the American Super Camp prepared Honda CRF 150’s.
