Product details

The Yoshimura RS-2 Enduro Series slip-on is a direct replacement muffler for the Kawasaki KLX300R, built around a stainless steel construction with an aluminium muffler. It is aimed at trail and enduro riders who want more usable power and a lighter tail end from an otherwise standard KLX300R.

Yoshimura matched the RS-2 muffler to the mid-size 300R after dyno development, claiming gains of 4% maximum horsepower and 4.2% maximum torque, along with a 3.5 lb (about 1.6 kg) saving over the standard unit. A USFS-approved spark arrestor comes pre-installed, so the muffler is ready for use where spark arrestors are required.

The RS-2 is designed and manufactured by Yoshimura in Chino, California, and is intended to fit a factory-standard motorcycle. Yoshimura notes that the system was designed and tested against US-market machines, so fitment and performance may vary in other markets, and other aftermarket or OE accessories not fitted from the factory may not be compatible.
