The KLX150BF offers riders serious off-road performance across a wide range of terrain. A simple, yet reliable air-cooled single-cylinder engine and highly rigid, box-section perimeter frame are complemented by an inverted front fork and large-diameter 21” front and 18” rear wheels. Its slim, compact package with low seat height, comfortable riding position and low-effort controls results in a bike that is easy to ride for new riders and satisfying for experienced riders.

Power Fuels Fun

The simple, air-cooled single-cylinder engine offers an easy-to-use and highly reliable power plant. Short gearing results in engine performance focused on the low-mid range, ensuring the strong low-end torque ideal for tackling tough off-road situations. And with electric start, starting is as easy as a quick push of the button.

144 cc Air-Cooled 4-Stroke Single

Simple, air-cooled engine offers strong, reliable performance and easy operation. The 5-speed transmission’s short gearing helps focus the engine performance in the low-mid rpm range, contributing to off-road potential.non-current colour shown.

Fun Starts at the Push of a Button

Electric starter ensures quick, hassle-free starting. A kick starter provides a reliable back-up should battery power be low.

A Full Day of Fun

With a capacity of 6.9 litres, the fuel tank contributes to the bike’s long range, enabling riders to enjoy a full day of trail riding on a single tank.

Highly Rigid Perimeter Frame

The high rigidity, compact size and light weight of the steel perimeter frame offer excellent handling qualities and contribute to easy manoeuvrability.

o35 mm Inverted Fork and Uni Trak Rear Suspension

Combined with the highly rigid frame, highly capable suspension ensures excellent handling and feedback. A o35 mm inverted fork at the front is complemented by Uni Trak rear suspension with adjustable spring preload.non-current colour shown.

Large-Diameter 21" Front and 18" Rear Spoke Wheels

On the KLX150BF, large-diameter wheels, measuring 21” at the front and 18” at the rear, are ready to overcome obstacles encountered on off-road trails, offering a high level off-road performance. Aluminium rims contribute to low unsprung weight.

Petal Disc Brakes

Petal disc brakes offer strong stopping power and good controllability. A o240 mm front disc gripped by a twin-piston caliper offers strong, easy-to-control braking. Slowing the rear, a single-piston caliper operates a o190 mm disc.

Ergonomics for Control and All-Day Comfort

The rider interface was designed to put the rider in a position to easily control the bike with minimal fatigue.non-current colour shown.

Aggressive Bodywork Inspired by Kawasaki Motocross Racers

Styling inspired by KX motocross racers gives the bike aggressive, sporty looks that reflect its off-road potential.

Easy-to-read instrumentation

Simple analogue instrumentation includes a speedometer, odometer, fuel gauge and indicator lamps, giving at-a-glance information to the rider.

Halogen Headlight

Sharp headlight design features a 35/35 W halogen bulb. A meter visor contributes to the aggressive looks.

Sharper Looks, Increased Protection

Fat-type handlebar contributes to the aggressive, racy image while offering increased rigidity. Handle covers, frame covers and a skid plate offer greater protection for rider and machine when off-road riding. Black rims like those on the KX factory race bikes add to the aggressive, racy image.
