Yamaha YZ 250

YZ 250 in brief

The YZ 250 is a competitive two-stroke cross motorcycle designed for tracks and training. It's lightweight, responsive, and highly regarded for its power and simplicity.

This model has been in production for over five decades, so different generations vary greatly — from old classics to modern ones with advanced suspension and frames.

Generations — what sets them apart

Earlier generations have simpler construction and less advanced suspension; they are favoured by collectors. Later generations feature liquid-cooled engines, improved frames, and better suspension.

Important distinction: the YZ 250 is a two-stroke, while the YZ 250 F is a four-stroke, making it a completely different model. There's also the YZ 250 X — a version tailored for cross tracks.

Engine and transmission

The engine is a single-cylinder two-stroke, around 250 cm³ in capacity. Two-strokes require a mix of oil and fuel, so you need to prepare the fuel according to the manufacturer's guidelines.

The gearbox is manual, with a hand-operated clutch. The power delivery of a two-stroke is more abrupt than a four-stroke, so it requires more experience to handle.

What to check when buying a used YZ 250

Ask when the piston, rings, and cylinder were last replaced. For two-strokes, these jobs are done more frequently than for four-strokes, so the service history is crucial.

Check the frame, suspension and rear shock absorber; look for any oil leaks in the chain. Check the exhaust system for any signs of corrosion.

Check if the engine starts easily, if the clutch operates smoothly, and if there are no signs of wear on the frame. When buying, it's especially important to know how the motorcycle was used.
