2023 Kawasaki KLX300 SM Technical Analysis & Specification Breakdown
At the heart of the 2023 Kawasaki KLX300 SM super motard motorcycle, Kawasaki relies on a 292 cc (17.8 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 78.0 x 61.2 mm (3.1 x 2.4 inches) with a 11.1:1 compression ratio.
On the scales, the KLX300 SM measures 138 kg (304 lbs) dry. Rider ergonomics and chassis geometry center around a 861 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,435 mm (56.5 in) wheelbase engineered for balanced agility and highway composure. The 7.57-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
