Yoshimura R&D of America Announce 2012 YZ250F/YZ450F RS-4 and RS-4D Applications

CHINO, CA – February 16, 2012 – (Motor Sports Newswire) – The RS-4 muffler was developed in conjunction with the Factory Suzuki race team with one purpose in mind: winning championships. The RS-4 is a unique design with predicated power, a side benefit of a quiet earthy exhaust note that speaks volumes for performance, and offers increased horsepower and torque. It is available as a full system, in either Titanium or Carbon Fiber, and comes with an ultra-lightweight carbon fiber end-cap.

The new RS-4D builds on the technology that has made the RS-4 a force to be reckoned with on the racetrack, enhancing its rock solid performance. The RS-4D 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, and offers increased horsepower and torque throughout the power curve, especially in the bottom to mid RPM range where riders need it most. The RS-4D is available as a full system, in either Titanium or Carbon Fiber, and comes with an ultra-lightweight carbon fiber end-cap.

Both the RS-4 and RS-4D has been used by both the Factory Honda and Factory Suzuki teams and is the system of choice for a number of the riders during the 2012 supercross and motocross seasons. RS-4 and RS-4D systems for the 2012 Yamaha YZ250F and YZ450F are now available.
