Overview
The Kawasaki KX 250 is a motocross bike in the KX family, produced from 1990 through 2027. For 2027, its 249.0 cm³ single-cylinder, four-stroke engine makes 48 hp (36 kW), and the motorcycle weighs 109.2 kg wet.
At 955 mm, the seat is tall and requires a long reach to the ground. The 109.2 kg wet weight helps when maneuvering the bike, while 305 mm of front travel and 307 mm of rear travel give the suspension room to work over rough track surfaces; adjustable damping and spring preload let riders tune the response. Electric starting makes firing up the fuel-injected engine straightforward, and the 6.20-liter tank carries a limited amount of fuel for longer sessions.

Pros and cons
Advantages
Adjustable suspension
Damping adjustment at both ends and rear spring preload adjustment let riders tailor the suspension response to the track.
Manageable wet weight
At 109.2 kg wet, the KX 250 is easier to maneuver than a heavier bike.
Electric starting
The electric starter makes restarting the engine more convenient than relying on a kick starter.
Things to consider
Tall seat
The 955 mm seat height can make it difficult for shorter riders to reach the ground securely.
Limited fuel capacity
The 6.20-liter tank carries little fuel for extended sessions before a refill.
