The Kawasaki KLX300S/SM has carved its way into many riders craving a need to get out and rip up the track, with an installed spark arrestor for hitting the trails.

The punch of the water cooled fuel injected 292cc engine comes alive with our RS-2 slip-on. Adding a max HP gain of 8% and a max torque gain of 9% making this little supermoto come alive. The RS-2 saves some weight too, alleviating 2.8 pounds from the stock muffler. This RS-2 includes an O2 sensor bung to accommodate the fuel technology of the KLX. With added power, torque and that distinct Yoshimura exhaust note, now we're talkin' fun!

This slip-on also fits the popular dual sport KLX250

Yoshimura's RS-2 is proudly designed, developed and manufactured in Chino, California.

Abigail ★★★★★

Bike feels noticeably punchier off the bottom now, and the spark arrestor is a nice touch for the dusty trails I mostly hit. The stainless build is solid, and it bolted on without fighting me. On the street the tone is deeper but not obnoxious, exactly what I wanted.

Sebastian B. ★★★★★

Bolted this on last weekend and the stainless finish looks clean against the black frame. It's noticeably lighter than the stock pipe and that deep growl at mid-throttle is exactly what the KLX needed.

Kevin B. ★★★★★

Pulled the trigger on this after reading the forums and it absolutely woke my bike up. The stainless construction feels really solid, and the spark arrestor lets me swap between track days and woods without any fuss. Just a clean bark at WOT, exactly what I was after.
