Yoshimura R-77 Stainless Slip-on Exhaust for the 2026+ Kawasaki KLE500

The Yoshimura R-77 Slip-On Exhaust (14500B0520) is a high-performance, race-bred muffler system engineered specifically for the 2026+ Kawasaki KLE500. Developed to unlock the full potential of Kawasaki's middleweight parallel-twin platform, this system replaces the heavy, restrictive factory silencer with a trapezoidal stainless steel muffler featuring a durable matte carbon fiber end cap.

Designed to optimize exhaust flow while maintaining a refined tone, the R-77 delivers a noticeable boost in power and throttle response throughout the mid-to-high RPM range. Beyond power gains, replacing the stock unit with this lightweight stainless steel slip-on significantly reduces overall weight at the rear of the motorcycle, improving chassis balance and handling. The system includes a USFS-approved spark arrestor, making it fully compliant for off-road trail riding and public lands access.

Features:

• Trapezoidal Design: Signature R-77 muffler shape maximizes internal volume while maintaining lean-angle clearance and a sleek profile.

• Performance Boost: Optimizes backpressure and exhaust flow to enhance mid-range torque and top-end power output.

• Weight Reduction: Significantly lighter than the OEM factory muffler, lowering the bike's overall center of gravity for improved maneuverability.

• Premium Construction: Durable 304 stainless steel muffler body paired with a lightweight matte carbon fiber end cap.

• Trail Compliant: Features a removable USFS-approved spark arrestor insert for legal off-road and adventure riding.

• Made in the USA: Designed, developed, and manufactured in Yoshimura's Chino, California facility.
