There's no F after the 2002 YZ250 so we're dealing with 2-stroke might, this time. This model year received a lot of improvements, starting with a new, lighter and tougher swingarm and recalibrated suspensions, with more precise travel and providing even more control.

In the engine department, the 2002 Yamaha YZ250 comes with a new cylinder head and combustion chamber, a reshaped exhaust port, and a revised second gear for explosive power deployment. The factory-spec racing clutch lever is adjustable, and the rear master cylinder and discs are also revamped.
