MODEL HISTORY

The Story of the KLX300SM

Introduced for the 2021 model year, this supermoto-styled entry in Kawasaki’s KLX family was created as the street-focused counterpart to the KLX dual-sport. Kawasaki presented it as an all-new lightweight model developed alongside its sibling, sharing core engine and chassis architecture while shifting the mission toward pavement, urban riding, and spirited cornering. From the start, the formula centered on a slim chassis, upright ergonomics, and supermoto cues that distinguished it from the off-road-leaning KLX line.

The nameplate arrived as part of Kawasaki’s broader revival of the KLX family, and it quickly established itself as the on-road personality in that lineup. Its identity is defined less by outright performance claims than by accessibility and playful handling: a small-displacement, liquid-cooled single, street tires, 17-inch wheels, and styling inspired by Kawasaki’s KX motocross machines. That combination made it appealing to riders who wanted a manageable machine with a dirt-bike attitude adapted for the street.

Kawasaki has kept the model in production through subsequent model years, with periodic updates to styling and equipment rather than a wholesale redesign. A refreshed version arrived for 2024, helping tighten its visual link to the rest of the KLX family while preserving the same basic supermoto concept. The model continued into later model years as part of Kawasaki’s lightweight street and dual-sport strategy, remaining the brand’s dedicated KLX supermoto offering rather than a one-off special edition or short-lived trim.
