KLX230SM

Built on the proven KLX230 platform, the KLX230SM pairs 17” front and rear wheels and road tyres with a Ø 37 mm inverted fork and road-oriented suspension. Stiffer springs and shorter travel give greater composure, with less front-end dive under braking. A large Ø 290 mm front disc with a twin-piston caliper and front ABS delivers sure stopping power.

Providing a light, manoeuvrable package was a key development consideration for the KLX230SM. Designing the simple air-cooled engine together with the perimeter frame resulted in a compact, well-balanced chassis that delivers nimble, agile handling for a wide range of riders, from city streets to winding roads.

The KLX230SM features a racing-inspired look that reflects the spirit of Kawasaki’s legendary KX racers—machines with over 50 years of success on the world’s racing stage. Its aggressive yet smooth bodywork takes inspiration from the KX450 and KX250 designs, bringing KX-style performance and image to a broader range of riders.

Based on the KLX230 off-road play bike, the KLX230SM features a lightweight 141 kg chassis (135 kg estimated dry mass). This low weight contributes to light, responsive handling at low speed, making the KLX230SM nimble in town and on winding roads.

Like Kawasaki’s motocross machines, a flat-style seat design offers great freedom of movement for sporty riding. Touring comfort was a consideration when deciding the seat shape (width) and thickness.

Kawasaki’s proven perimeter frame, designed from the start with off-road riding in mind, delivers confidence-inspiring handling. Feedback from Kawasaki motocross test riders was used to optimise the engine-frame mass balance, contributing to sporty handling on the street.

Smooth-shifting six-speed transmission covers a wide range of street-riding situations and enables riders to keep the engine in the power band on winding roads, while also contributing to more comfortable cruising on the highway. A smaller 43T rear sprocket gives longer final gearing to match the 17” wheels.

Designed to assist riders to stop effectively in a short distance, the KLX230SM’s front-wheel ABS offers additional confidence to riders, especially on slippery road surfaces.

The fuel tank, shrouds and side covers form a single, flowing surface with minimal protrusions, contributing to sharp, functional KX-style bodywork. A blacked-out frame, swingarm, handlebar and rims, together with a sporty front fender matched to the 17” front wheel, give the KLX230SM an aggressive supermoto image.

The KLX230SM’s engine offers ample power for everyday riding. With a bore and stroke configuration chosen to prioritise torque, the engine delivers strong low- to mid-range performance that facilitates low-speed control in town. Fuel injection delivers precise response and contributes to controllability. Smooth torque characteristics create an easy-to-handle engine character and deliver linear acceleration.

Designing the engine and frame together allowed greater design freedom. Great care was taken to minimise engine height, which allowed an optimal frame line to achieve the ideal rigidity balance as well as keeping the seat height low. The short wheelbase contributes to the bike’s manoeuvrable handling— another welcome feature for a wide range of riders.

A compact LED headlight with remarkable brightness is the centrepiece of the KLX230SM’s sporty, aggressive front end. The unit is short front-to-back, giving the area a sleek look, while the headlight cover contributes to the design.

A Ø 37 mm inverted fork contributes to sporty supermoto looks as well as front-end rigidity. At the rear, New Uni-Trak suspension with a preload-adjustable, gas-charged shock provides great bump absorption and a planted feel. Road-oriented settings with stiffer springs and shorter travel (F: 188 mm, R: 195 mm) offer greater composure, with less front-end dive under braking.

17” front and rear wheels fitted with road tyres (F: 110/70-17, R: 120/80-17) contribute to the KLX230SM’s agile, nimble handling on the street.

Choosing air-cooling and a simple SOHC 2-valve design for the engine afforded numerous benefits. Compared to liquid-cooled engines, fewer parts are required, contributing to a lighter, more compact chassis. The simple configuration delivers a user-friendly character ideal for everyday riding, while also offering the kind of performance riders expect and appreciate.

A large Ø 290 mm front disc with a twin-piston caliper delivers sure stopping power while adding to the supermoto looks. At the rear, a Ø 230 mm disc with a single-piston caliper slows the bike.

In place of the off-road-style footpegs of the KLX230, the KLX230SM’s rider footpegs feature rubber pads for increased ride comfort.
