TL;DR What Actually Makes the KX450SR Different From a Standard KX450 credit: https://dirtbiketest.com/ The KX450SR isn’t a new model. It’s the standard KX450 with a specific parts package bolted on at the factory, and Kawasaki has used the “SR,” or Special Racer, badge on Team Green race bikes for decades. For 2025, that package includes…

TL;DR What Makes the KX450X Different From the Standard KX450 The KX450X is Kawasaki’s cross-country variant of the KX450 motocrosser, built for GNCC-style off-road racing instead of closed motocross tracks. It shares the same aluminum perimeter frame, 449cc engine, and Brembo front brake as the KX450, but almost everything around that core is retuned for…

TL;DR What Are the 2026 Kawasaki KX450’s Key Specs? credit: https://www.cyclenews.com/ The KX450 is Kawasaki’s flagship 450cc motocross bike, built around a 449cc fuel-injected DOHC single-cylinder engine in an aluminum perimeter frame. For 2026, the platform carries over unchanged from 2025, meaning the frame, engine internals, suspension, and electronics package are identical to the previous…

TL;DR What Does the Kawasaki KX250X Put Out in Horsepower and Torque?

Kawasaki hasn’t published a separate dyno figure for…

The 2026 KX250 makes 39.2 hp and 18.7 lb-ft of torque at the rear wheel, measured on Dirt Rider’s in-house Dynojet 250i dynamometer (Dirt Rider, 2025). That figure is unchanged from 2025, since Kawasaki carried the engine over with zero mechanical updates for 2026. Worth knowing:…

TL;DR What Does the Kawasaki KX112 Engine Put Out? Kawasaki doesn’t publish a crank or rear-wheel horsepower number for the KX112, and that’s normal for this class of bike. Youth Supermini machines are built for closed-course racing, not street use, so manufacturers skip the horsepower spec sheet entirely and let lap times do the talking….

The KX65 uses a 64cc liquid-cooled, single-cylinder two-stroke engine with an 8.4:1 compression ratio and a 24mm Mikuni carburetor feeding the mixture (Kawasaki, 2026).

Dirt Rider put a 2021 model on its in-house Dynojet 250i dyno and recorded 17.9 hp at 7,700 rpm and 14.4 lb-ft of torque at 6,100 rpm…

TL;DR What Are the Kawasaki KLX140R’s Full Specs? The KLX140R is a 144cc air-cooled trail bike with a 5-speed manual transmission, a Keihin PB20 carburetor, and a steel perimeter frame. It’s the small-wheel version of Kawasaki’s KLX140 family, sitting under the KLX140R L and KLX140R F in wheel size and seat height (Kawasaki, 2026). Spec…

TL;DR How Much Horsepower Does the KLX110R Make? Kawasaki doesn’t publish a horsepower figure for the KLX110R, which is normal for this class of youth off-road bike. The most reliable number comes from independent dyno testing rather than a factory spec sheet. In a 2021 dirt bike shootout that put the KLX110R on a dyno…

TL;DR What’s the Kawasaki KLX230 DF’s Top Speed? The KLX230 DF hasn’t been independently GPS-tested yet since it’s a new 2026 trim, but it shares its 233cc engine, gearing, and chassis with the standard KLX230, which has been tested. Riders clocked the standard KLX230 S at about 73 mph in sixth gear (ADVMoto, 2023), and…

TL;DR What’s the Kawasaki KLX230 Sherpa S’s Actual Top Speed? The Sherpa S tops out at roughly 75 mph before the rev limiter shuts things down, according to a first ride test from RevZilla, which put an actual tester on the bike with the throttle pinned (RevZilla, 2026). That’s a real-world figure, not a manufacturer…

TL;DR What’s the Kawasaki W230’s Top Speed? Kawasaki hasn’t published an official top speed for the W230, and as of this writing, no major outlet has run one through a GPS speed trap either. That’s not unusual for a bike this size; a 233cc single making 17 hp just isn’t a priority for that kind…

TL;DR How Fast Is the Kawasaki W175 LTD? The W175 LTD isn’t built to chase a speedometer needle. Kawasaki hasn’t published an official top speed or 0-60 figure for the U.S.-spec LTD, so the numbers below come from GPS-instrumented testing of the mechanically identical international-market W175, which shares the same 177cc engine, gearing, and chassis…
