RS-4 Works Finish Slip-On Exhaust System - KTM 790/890/901 Adventure

Yoshimura has developed an RS-4 slip-on that delivers in every area that an adventure rider would desires - power, sound and looks. The power that the RS-4 provides is second to none, delivering a 5.5% max gain in horsepower and a 4.7% max gain in torque. The sound the RS-4 provides is throatier, and with over a .2 lbs. weight loss, acceleration and throttle response has been improved dramatically. Finished off with Yoshimura's own Works Finish and you have a winner.

Proudly made in the USA

New Yoshimura Works Finish takes on a unique coloring after it goes through a heat cycle on the motorcycle that looks much like those titanium works components our factory racers use.
