Kawasaki Malaysia has expanded its KLX family with the launch of the 2025 Kawasaki KLX230S dual-purpose and KLX230SM supermoto, officially introduced in Malaysia by Motosikal dan Enjin Nasional Sdn. Bhd. (MODENAS) back in September. While both models aim to bring versatility and adventure to riders, it was the KLX230SM that really caught our attention, a compact, entry-level supermoto designed purely for fun.

The KLX name itself carries serious weight. It’s a badge that dates all the way back to 1979, and the KLX230SM continues that legacy in a modern, road-focused form. First seen in Australia in early 2023, the 230SM swaps dirt wheels for 17-inch rims, road tyres, sportier geometry, revised suspension settings, taller gearing, and larger front brakes. 

As the smaller sibling to the KLX300SM, honestly, this bike feels like an open invitation for new riders who want supermoto styling without being overwhelmed. We had the chance to live with the KLX230SM for a few days, and honestly, it didn’t take long to understand what this bike is about: simple, lightweight fun.

First Impressions and Specs

Power comes from a 233cc air-cooled, SOHC single-cylinder engine, paired to a six-speed gearbox and chain final drive. On paper, it makes 19.73 bhp at 8,000 rpm and 20.3 Nm of torque at 6,000 rpm. The frame is a steel cradle design, and the suspension setup is intentionally basic. There are no fancy electronics or adjustable clickers here, and that’s kind of the point.

The bike tips the scales at just 133 kg, with a seat height of 845 mm. It might sound tall on paper, but in reality, the narrow seat and slim body make it manageable for most riders above 160 cm. The reach to the handlebars is short, steering lock is generous, and everything feels compact and easy to control from the get-go.

Riding Experience: Instant Grin Factor

From the moment I rolled the KLX230SM out of the driveway and onto the street, it put a smile on my face. The engine feels peppy and friendly, making it just as enjoyable cruising through neighbourhood roads as it is blasting down town. For beginners, this bike is almost the perfect introduction to motorcycling, unintimidating, forgiving, and confidence-inspiring.

The narrow supermoto seat helps you get both feet down easily, and the slim profile means you’re never wrestling with the bike at low speeds. This is especially important for new riders, because slow-speed control is often the most intimidating part of riding.

Ergonomically, the KLX230SM nails the supermoto formula. The upright seating position gives excellent visibility in traffic, the wide handlebars provide great leverage, and the relaxed body position feels natural almost immediately. The clutch pull is light, the controls are easy to reach, and while the non-adjustable levers sit a bit far out, they’re still manageable.

Engine Character and Performance

The little 233cc machine might not sound exciting on paper, but on the road, it’s a blast. There’s a satisfying pull off the bottom, making it easy to get moving from a standstill. Torque builds smoothly through the midrange before tapering off, and there are no nasty surprises in the power delivery. Whether you’re cruising calmly or pushing a bit harder into corners, the engine stays predictable and smooth.

This isn’t a highway missile, and it’s not trying to be. Long, high-speed cruising isn’t the KLX230SM’s strong point. I managed to hit 120 km/h, and you can feel that the bike wants to give more, but it’s clearly restricted by the ECU. The gearing is short, revs build quickly, and you’ll find yourself shifting up often. On the flip side, that short gearing makes acceleration fun, and yes, clutch-up wheelies in first gear come easily, and even second gear if you’re feeling cheeky.

Handling and Suspension

There’s no suspension adjustment up front on the 37 mm Showa upside-down forks, and only preload adjustment at the rear shock, but the setup works surprisingly well. Around town, it absorbs rough roads without drama, and when the roads get twisty, the bike feels composed and eager to change direction. On the highway, expansion joints can feel a bit harsh, but that’s a trade-off you expect from a lightweight supermoto.

Thanks to its low weight, the KLX230SM is incredibly fun to flick through corners. After rolling the handlebars back slightly, adjusting the levers, and setting the mirrors, the riding position felt even better for spirited riding. This bike also screams custom potential. A full exhaust, intake, suspension tuning, sticky tyres, and some graphics would transform it into a seriously cool little weapon.

The Downsides

It’s not perfect, of course. The simple digital LCD dash does the job, showing speed, fuel level, clock, and trip meter, but the brake line partially blocks the display from certain angles. I often had to lean forward or push the line aside just to see it clearly. There’s also no gear indicator, which feels like a missed opportunity but i understood, supermoto style. 

Here in Malaysia, the bike does come with Kawasaki Smart Connectivity, allowing Bluetooth pairing with your smartphone, but the screen itself remains basic and monochrome.

Another gripe, and a big one for supermoto fans, is the non-switchable ABS. You can’t turn it off from the factory, which takes away some of the fun. Yes, you can unplug the ABS socket somewhere behind the bodywork, but honestly, this should’ve been a standard option, especially for the SM variant.

Final Thoughts

The 7.6-litre fuel tank is more than enough thanks to the bike’s excellent fuel efficiency, and throughout our time with it, the KLX230SM didn’t miss a beat. It’s light, fun, beginner-friendly, and full of character.

Priced at RM 23,600 (On-The-Road). Is it a bit pricey? Maybe. But for riders who fall in love with the supermoto lifestyle, this bike will make sense. It’s a fantastic entry-level machine, a great city play bike, and something I’d happily keep in my garage just for fun. Small cc, big personality. And honestly, that’s what makes the 2025 Kawasaki KLX230SM such a joy to ride.
