Honda CRF300 Rally 2021 - 2025 Yoshimura Race RS-4S Full Exhaust w/Stainless Muffler

Yoshimura Race RS-4S Full Exhaust w/Stainless Muffler

One of the fastest growing segments of the motorcycle market is the Dual Sport segment and we love the smaller bore dual sport bikes as they are an entry level to get more riders into the sport.
We stepped up to the plate and developed our RS-4 Full System for the all-new Honda CRF300L and Rally edition, the results were fantastic! The full system gives the new CRF up to 5.9% max HP while improving the power across the entire spectrum enabling the 286cc engine to optimize performance while saving significant weight.
The sound of the RS-4 is unmistakable, on idle and under load the exhaust note is music to ones ears. Also available is our USFS approved spark arrestor for those riders wishing to take to the trails in the great outdoors.
Proudly made in the USA!
