About this model
About the Yamaha DS 7
The Yamaha DS 7 is a 250cc air-cooled two-stroke twin from 1970–1972 and a direct predecessor of Yamaha's RD models. It combines a lively piston-port engine with a relatively light road chassis and drum brakes. The DS 7 was quick and appealing for a classic, but needs a different riding style and maintenance discipline from a modern motorcycle.
Buy a good example on mechanical history rather than paint alone. Check crankshaft, pistons, oil pump and carburettors, and establish whether tank, exhausts and side panels are original or correct reproductions. A test ride should show a clean transition into higher revs without detonation or excessive smoke. For collectors and enthusiasts, the DS 7 is a special lightweight two-stroke for sunny rides; expect parts research and regular workshop time.

Before you buy
What to check before buying
- Check compression and crankshaft noise and ask for evidence of piston and crank rebuilding.
- Inspect oil pump, lines and carburettor setting; air leaks and lean running damage two-stroke pistons.
- Inspect tank and exhausts for corrosion and ensure the airbox is complete.
- Test drum brakes, cables, rims and electrics; original parts can be scarce.
