All-new KX450-style bodywork features long, smooth surfaces and a flatter tank-seat line designed to facilitate rider movement and control.

Additional engine updates increase peak power of the already powerful engine by approximately 1.0 kW (1.4 PS). Rev limit increases a further 350 min-1.

Electric start makes restarting the engine as easy as pushing a button.

Updated suspension settings contribute to increased bump absorption and traction, while minor brake component revisions enhance controllability.

Like the KX450, a hydraulic clutch offers more direct feel and lighter lever action. Less play as the clutch heats up during heavy use results in more consistent feeling.

KX450-based frame (an evolution of the current design) and KX450 swingarm offer improved handling and increased rear wheel traction.

Factory-style Ø 28.6 mm Renthal aluminium Fatbar, a popular aftermarket part, is now a standard feature. The thicker handlebar helps reduce vibration and shocks transmitted to the rider, while the new grip position (19 mm lower, 8 mm closer) helps put the rider in a position that makes it easier to weight the front wheel.
