The ultimate upgrade for the highly anticipated 2026 Kawasaki KLE 500 has arrived. The development team at Yoshimura R&D of America has custom-tuned our legendary R-77 specifically for Kawasaki’s new middleweight adventure platform, matching its rally-inspired aesthetics right out of the box utilizing the distinctive the iconic trapezoidal profile.

Under throttle, the system unlocks a beautiful, deep bark from the KLE 500's 451cc parallel-twin engine while remaining completely low-volume sound insert capable. In the performance department, the Yoshimura R-77 Street Series slip-on delivers up to a 1.8% increase in horsepower at 6,600 rpm and up to 3.9% more torque at 5,000 rpm, all while shaving nearly 3 pounds of restrictive factory bulk from the rear of the machine. The system is beautifully finished with a custom Yoshimura carbon fiber heel guard, protecting the rider from heat when standing on the pegs.

Benjamin S. ★★★★★

Installed it in about 20 minutes and the stainless muffler has a much deeper, throatier tone than stock—no need for rejetting either.

Sebastian X. ★★★★★

That first ride with the new exhaust had me grinning the whole way home—the stainless muffler gives it a deep, throaty growl that’s completely different from stock. The sound alone makes the bike feel like a whole new machine, and the quality of the welds is spot on.

Robert ★★★★★

The installation was straightforward and the stainless muffler looks way better than the stock plastic piece. It's noticeably lighter too, and the throttle response feels crisper right away.
