Overview
The Yamaha YZ250FX is a motocross bike produced from 2015 through 2027. The 2027 model has a 250 cm³, single-cylinder four-stroke engine producing 37 hp (28 kW), with a wet weight of 110.2 kg.
Its 955 mm seat is high, which can make it difficult for shorter riders to put both feet down. The KYB® fork and rear shock are fully adjustable, while 300 mm of front travel, 305 mm of rear travel and 330 mm of ground clearance give the suspension room to handle uneven terrain. Electric starting avoids the need to kick-start the engine, and the 8 L fuel tank limits how much fuel it can carry between refills.

Pros and cons
Advantages
Adjustable KYB® suspension
Both ends can be adjusted, letting riders tune the suspension to their preferences and riding conditions.
Generous wheel travel
The 300 mm front and 305 mm rear travel provide room for the suspension to absorb large bumps.
Electric starting
The electric starter makes restarting simpler than relying on a kick starter.
Things to consider
High seat
At 955 mm, the seat may make it hard for shorter riders to reach the ground securely while stopped.
Limited fuel capacity
The 8 L tank carries a limited amount of fuel, so refills may be needed sooner than with a larger tank.
