Kawasaki KXF250 2017-2020 Yoshimura RS-4 Full Exhaust System
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
- Weight: 0.4 lbs lighter than stock configuration
- Repack Kits, optional Inserts and Spark Arresters are available for all models
