Being able to restart an engine quickly during a race can mean the difference between keeping your lead, or having to fight your way back through the pack. Electric start makes restarting the engine as easy as pushing a button.

A hydraulic clutch offers direct feel and light lever action. Less play as the clutch heats up during heavy use results in more consistent feeling. The use of coned-disc springs contributes to lighter clutch actuation when the lever has been pulled in, and a wider clutch engagement range, which facilitates control (especially when half-clutching). New material for the clutch pushrod in 2023 (now an aluminum shaft with a steel cap) results in lighter clutch operation.

Lightweight and designed for the rigours of off-road riding, the ECU contains multiple programmable engine maps to offer riders an advantage on the race course. Using the provided DFI couplers, riders are able to easily switch from one to another of the three engine maps to suit riding conditions. The plug-and-play style system is quick, easy and stress-free. Each of the three maps can be reprogrammed using the optional KX FI Calibration Kit.

Factory racer-style launch control system increases the chance of getting a good start by helping riders maximise grip when starting on a low-traction surface.

Front and rear suspension setting updates in 2023 contribute to improved cornering. On corner entry, greater front-end feedback contributes to a more planted feel. Increased ground-holding performance makes it easier to hold a chosen line through the corner. After exiting the corner, revised rear suspension settings contribute to stronger acceleration.

Oversized semi-floating ø270 mm front disc contributes to strong front brake force, as well as superb controllability. The KX450-type front master cylinder adds to the high level of control and overall feedback from front brake.

Dunlop MX33 tires offer increased traction to match the engine’s increased power, while a wider 110/90-19 rear tire (previously 100/90-19) contributes to increased rear wheel traction as well as a greater planted feeling.

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

A choice of four handlebar positions and two footpeg positions allows riders to tailor their riding position to suit body size and preference. Factory-style ø28.6 mm (1-1/8”) Renthal aluminum Fatbar helps reduce vibration and shocks transmitted to the rider, while a lower, closer grip position helps put the rider in a position that makes it easier to weight the front wheel.

Revised footpeg design as of 2023 is 5 mm wider (front-to-rear) and positioned 3 mm rearward, offering excellent grip, superb feel, and making it easier to weight the pegs. Aluminum brackets contribute to weight reduction.
