Factory teams do their homework. Years are spent testing and retesting the best equipment on the market. Power is king in outdoor motocross and Yoshimura produces power. The pipe of choice for Rockstar Energy Suzuki/MotoSport?s Factory Lites team, Yoshi has proven to rise above the rest. Bobby Hewitt, Rockstar Team Owner states, ?We work hard to put the best bike possible out on the track every year. In order to do that we spend countless hours testing equipment. We choose Yoshimura over the rest because of the smooth power it provides and the overall reliability of the product.
Wake up the performance of your dirt bike with the addition of the Yoshimura RS-4 complete exhaust system.
Yoshimura designed the RS-4 exhaust to match the performance needs of your bike across the entire RPM range.
After extensive testing the Yoshimura RS-4 complete exhaust system was able to get nearly 10% horsepower increase and a boost in torque.
The engineered design of the RS-4 reduces overall weight and lowers the center for gravity of your bike for better handling.
Yoshimura used a stepped header design to optimize the flow through.
The RS-4 muffler features a new front cap design that functions as a polyresonant camber, which reduces dB's and improves mid to top end power.
To offer extreme durability Yoshimura utilized titanium for the header and mid-pipe and sheds weight with the titanium muffler sleeve on the RS-4.
Yoshimura includes an AMA Pro Racing sound insert.
