The 2021 Kawasaki KLX 300SM: A Full-On Race Bike For The Streets
The 2021 Kawasaki KLX 300SM is a brand new model from the venerable Japanese brand. Based on the KLX 300R platform, the 300SM takes the off-road bike and wraps it in full street gear. It uses the same 292cc liquid cooled, four stroke single, with the same 33 HP and 21 lb-ft of torque, but redoes the ECU and cam profiles to give it much more aggressive acceleration.
Kawasaki’s designers then lifted the off-road wheels off the bike, giving it 17 inch front and rear wheels wrapped in street rubber. It then ups the front brake disc to a 300mm semi-floating disc, and stiffens the suspension significantly, albeit allowing the rear shock to be fully adjustable.
The final modifications are a headlight, fully digital instrument cluster, indicator lights front and rear, a narrower handlebar than the 300R, and a license plate holder to make it fully street legal. It is fully capable of racing in supermoto tarmac competitions, but is more intended for those wanting to have a “trail bike for the street,” a market that KTM and Suzuki have enjoyed much success in.
The 2021 Kawasaki KLX 300SM starts at $5,999 USD / $6,799 CAD.
