The 2021 Kawasaki KLX 300R: The Bridge Between Trail Bike & Race Bike

The 2021 Kawasaki KLX 300R is the top of the line trail bike from the Japanese brand. Using knowledge gained from Kawasaki’s motocross and supercross racing programs, a liquid cooled, super-lightweight, four stroke 292cc single is the thrumming heart of the motorcycle. With 33 HP and 21 lb-ft of torque, the objective is not to yank the riders’ arms out of their sockets as much as give them enough power to conquer any trail obstacle.

This Kawasaki off-road bike has a six speed transmission, 11.2 inches of fully adjustable suspension travel front and rear, and motorsports grade front and rear petal-disc brakes. A full 12 inches of ground clearance also allows for scrambling, if needed, over obstacles.

Another carry-over from the racing program is the bike’s lightweight perimeter frame, which cradles the engine while also providing durability that has been proven time and again on the track. With all the weight saving, this substantially larger bike is only 28 lbs more than a KLX230R.

The 2021 Kawasaki KLX 300R starts at $5,499 USD / $5,999 CAD.
