New from Yoshimura R&D is a range of exhaust slip-on kits and full systems for the latest 2018 dirt bike models.
It's been a long time coming, but its finally here. The 2018 Honda CRF250R is brand new from the ground up, and Yoshimura is ready to provide the race power the new red machine craves!
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. Yoshimura have developed the 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 is what Yoshimura do, and they have found some great additions for the new CRF250R.
Not only increasing the bottom, mid and top power, a reduction in weight of up to 1.5Kg can be achieved as well as an overall decrease in dB noise level of the stock system.
