Vehicle Information
Kawasaki KX450 Dirt Bike (1974-2026)
The Kawasaki KX450, a leading motocross motorcycle, has been a cornerstone model since its introduction as a 2006 model year. It consistently features a 449cc liquid-cooled, DOHC, four-stroke single-cylinder engine across all model years from 2006 to 2026. This high-performance dirt bike is renowned for its competitive capabilities on the track. The KX450 has undergone several significant generational shifts. The second generation in 2009 introduced Electronic Fuel Injection (EFI) and a new lighter frame. The third generation (2012-2015) brought Launch Control and DFI coupler systems for engine mapping. A major engine and chassis lightening marked the fourth generation (2016-2018). In 2019, the "F" designation was dropped, and the fifth generation introduced electric start, a new slimmer aluminum frame, and a hydraulic clutch. The latest, sixth generation, starting in 2024, features a new frame, plastics, and improved engine performance with symmetrical intake and exhaust alignment. Various trims like the KX450X (cross-country) and KX450SR (Special Racer) have also expanded its range since 2021 and 2022, respectively. FAQ:
