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.

2021 Kawasaki KLX 300R Features
Proper fit is key for rider comfort and control. However, the ideal fit varies from rider to rider, depending on their physical dimensions and riding style.
ERGO-FIT® is an interface system designed to allow riders to find their ideal riding position. Various points of the chassis interface (the handlebar, footpegs and seat, etc.) can be adjusted through a combination of interchangeable parts and parts with adjustable positions. This enables a wide range of riders to find a riding position that offers both comfort and control. Feeling at one with their machine, they will be able to experience how Kawasaki machines are fun and rewarding to ride.
