Power Up Your 2011 YZ250F With a Yoshimura RS-4

  • Power Up Your 2011 YZ250F With a Yoshimura RS-4

Chino, Calif. – Getting the most out of an engine is what the engineers at Yoshimura R&D do best, and they've wasted no time in developing a new version of their race-proven RS-4 exhaust system to maximize the performance of the 2011 Yamaha YZ250F. This bike's engine was redesigned to make more power through the low and mid range, while maintaining the top-end rush that has made the bike so popular among motocross racers. By adding a Yoshimura RS-4 slip-on or full system, riders will feel a significant boost in power and torque all the way from idle to redline.

The RS-4 is Yoshimura's most advanced off-road exhaust system yet. The compact RS-4 muffler utilizes a duplex chamber design to maximize flow while offering excellent noise reduction. The end result is a lightweight muffler that will lower sound emissions while increasing performance. RS-4 systems can be tuned to match whatever noise restrictions you might face through interchangeable sound inserts, which range from the USFS approved spark-arrested insert to the AMA pro racing legal insert.

All RS-4 exhausts are manufactured from the highest quality lightweight materials, and come in a variety of finishes. The slip-on model features stainless/aluminum construction, and a stylish carbon fiber end-cap to set your machine apart. Full systems are available in stainless/aluminum, titanium, or titanium/carbon finishes.
