Full Size Wheels

Large 21” front and 18” rear tyres provide strong off road capability. Large wheels are better to overcoming obstacles encounted when taking the bike through off road trails or tackling the unpredictable roads of the urban environment.

Large Petal Disc Brakes

The 240 mm front petal disc is gripped by a twin-piston caliper and when combined with 190 mm rear petal disc and single piston caliper offers strong easy-to-control braking. The front and rear calipers use sintered brake pads for good wear characteristics.

Strong, Reliable Engine

The engine in the KLX150BF offers a simple, easy-to-use and highly reliable power plant. The 144 cm3 4-stroke air-cooled single-cylinder engine offers a lightweight power plant with both reliability and strong performance. Large Keihin NCV24 carburettor ensures smooth throttle response and excellent fuel economy.

Halogen Headlight

Sharp headlight design fetures a 35/35 W halogen bulb. A new meter visor contributes to the aggressive appearance.

Inverted Front Fork

With 35 mm diameter inverted front fork offers a serious boost to off-road riding potential. Increased bottoming resistance eliminates bottoming on off-road trails. Wheel travel measures a large 175 mm. New gold finish on the inverted forks enhance the appearance of the 2018 KLX150BF SE model.

Gas Charged Rear Shock

Single rear shock absorber with pressurised nitrogen gas is 5-way adjustable for preload, allowing riders to set the bike up for their weight.

Uni-Trak Rear Suspension

Uni-Trak rear suspension with 192 mm of wheel travel provides great road holding ability and bump absorption. Shock settings suit the large wheel sizes.


A combination of form and function, the frame was also designed to be easy to grip with the legs, offering superior chassis control to the rider. Throttle grips are the same as those on our top-class MX racers. Raised pattern on half of the surface makes them easier to grip. Fat bar contributes to the aggressive, racy image while offering increased rigidity. The handlebar is rubber-mounted for reduced vibration transferred to the rider’s hands. Further, the upper triple clamp and handle clamp are separate pieces, making it easier to install an aftermarket handlebar.


Simple analogue instrumentation includes a speedometer, odometer, fuel gauge, turn signals indicator, high beam warning light and neutral light.

5-Speed Transmission

5-speed transmission ensures there is a gear for every situation, enabling quick pick-ups when accelerating from a stop, and relaxed cruising ability when riding at higher speeds. Short final gearing care of large rear sprockets KLX150BF: 52/14 focuses the engine’s performance in the low-mid rpm range. This contributes to increased off-road performance, the stronger low-end enabling riders to continue moving forward even when navigating tricky off-road trails.

Lightweight Aluminium Rims

Lightweight, black alumite aluminium rims enhance the appearance and handling.

Flat Seat Design

The flat design of the tank and seat gives the rider greater freedom of movement when changing riding position, and facilitates sitting farther forward. Like our KX racers, the KLX150BF features a two-tone seat leather.

6.9 Litre Fuel Tank

With a capacity of 6.9 litres the fuel tank contributes to the KLX150BF long range, enabling riders to enjoy a full day of trail riding on a single tank.

Hand Guards

Hand guards help protect the hands when off-road riding.

Engine Guards

Engine guards help protect the engine when off-road riding.

Frame Guards

Frame guards help protect the frame when off-road riding.

Low Exhaust Emissions

Exhaust emissions clear Euro-III emissions regulations. A larger catalyser (located at the silencer entrance) ensures emissions regulations continue to be met with the shorter gearing. Silencer feaures an oval cross section, giving it a sharp aggressive design.

Aggressive Taillight Design

Aggressive taillight design complements the bikes’ racy image. The long rear flap integrates the rear turn signals for a compact, tidy design. Handy tool box located on the inside of the left side cover features everything necessary for quick, on-the-spot maintenance jobs.


The KLX150BF SE is covered by a 24 Month Factory Unlimited Kilometer Warranty for added peace of mind.
