Honda CRF 250R Dual Exhaust Off-Road Motorcycle

Description

The CRF250R’s new twin cam engine and unique muffler configuration gave us the opportunity to create an entirely new system built specifically for the new dual port cylinder and its unique downdraft fuel injection system. We’ve developed our potent RS-9T Signature Series exhausts to provide more bottom end power and improved torque for the new high-revving engine. The distinctive dual header design is a brand new innovation from Honda. Deriving from Moto 3 bikes in Moto GP, Honda has found a new way to look at Motocross power delivery. Honing the power, engineers in Japan develop is what we at Yoshimura do, and we have found some great additions for the new CRF250R.

Not only increasing the bottom, mid and top power, we have been able to reduce the weight from stock by half a pound, as well as an overall decrease in dB noise level of the stock system.
