Product details

The Yoshimura RS-9T Signature Series system is designed from scratch for the CRF250R, with its twin cam engine, dual port cylinder, downdraft fuel injection and unusual silencer layout. The dual header design is a new Honda idea taken from Moto3 machines in MotoGP, and Yoshimura has developed this exhaust to add bottom end power and torque to the high-revving engine.

Power is increased across the bottom, mid and top of the rev range. The system is also half a pound lighter than the standard system and lowers the overall dB noise level compared with the standard exhaust.

Key features

• Tested on the dyno and on track by Honda R&D in Japan and the HRC All Japan MX Racing Team

• Spark arresters, repack kits and optional inserts are offered for every model
