Yamaha's YZ250F is the choice of many rippers in the 250 class. Yoshimura, in our endless endeavor to make the best, most usable power, we have refined our Yamaha YZ250F full systems.

Our new RS-4 systems deliver 12% peak HP and 11% peak torque while enabling the YZ250F to have a more linear, more usable power curve. With our new systems the blue machine is much easier to handle while providing more power! That's a win/win in anyone's book.

The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. We've developed the current generation RS-4 based on that research & development, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a Polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling.

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Stainless steel header and tail-pipe
