ARE YOU READY FOR THE ALL-NEW 2025 KAWASAKI KX250?

2025 Kawasaki KX250 is as new as new can be.

A new 2025 KX250 follows in the footsteps of last year’s all-new 2024 KX450. For 2025, the obvious KX250 updates are the sleeker bodywork and a new, refined KX450 chassis. There are also big changes to the 2025 KX250 powerplant, including a center-port exhaust to work with the new frame, single-shaft counterbalancer, lighter crankshaft, stronger connecting rod, repositioned dual-injector nozzles, freer-flowing airbox and domed air filter. Most of the 2025 top-end changes are based around the new airbox, domed filter and straighter intake angle; the intake now sits above the 32mm-lower shock tower.

The 2025 KX250 has dropped last year’s Kayaba suspension for special 48mm Showa forks (not the 49mm forks from the KX450). The rear Showa shock is the same design as found on the KX450.
