Yoshimura RS-4D Exhaust System Honda CRF250R
When it comes to exhaust systems designed for competition, Yoshimura and the Team Yoshimura Suzuki race team have always worked toward a single goal: helping you win. A perfect example of the result of our single-minded focus is the Yoshimura RS-4D Exhaust System. It builds on the technology that made the RS-4 incredibly successful on the racetrack and enhances its exceptional performance.
The RS-4D Exhaust boasts a unique dual-outlet design that increases the amount of open area at the exhaust outlet. With dual internal baffles, the RS-4D increases the exhaust gas flow rate, resulting in smoother power delivery and increased throttle control. It also offers increased horsepower and torque throughout the power curve, especially in the bottom- to mid-RPM range where riders need it most.
