Info Photos Specifications

Sitting at the top of the KX™ motocross lineup is the 2026 Kawasaki KX™450. This race-focused machine pairs a 449cc four-stroke single with a chassis shaped by Kawasaki's championship experience, allowing riders to push hard on the track from the opening lap through the final one.

• 449cc DOHC engine: a 4-valve, liquid-cooled single fed by Keihin 44mm throttle-body fuel injection, pulling strongly from low through mid revs.
• Hydraulic clutch: delivers a consistent, light lever feel throughout long motos.
• Showa suspension: up front sits a 49mm coil-spring fork, and out back a fully adjustable shock offers high/low-speed compression; both provide about 12 inches of travel.
• Brembo front brake: stopping that's strong and controllable comes from a 270mm semi-floating disc.
• Aluminum perimeter frame: light and slim for handling precision.
• 5-speed transmission: paired with a chain final drive.
• Dunlop Geomax MX34 tires: a 21-inch front and 19-inch rear to deliver grip on the track.
• Signature Lime Green: the classic racing colors of the KX™.
