About this model
About the Yamaha RD 400
The Yamaha RD 400 is a 398cc air-cooled two-stroke twin from the latter half of the 1970s. It is the larger, more powerful development of the early RD family, combining strong middleweight performance with classic hardware: twin carburettors, Autolube lubrication, spoked wheels and simple brake and suspension components. The engine responds eagerly when ignition and carburation are right, but it rewards an owner who understands maintenance.
At purchase, prioritise crankshaft, cylinders, oil supply and corrosion over cosmetics. Confirm the frame is straight, brakes and suspension work properly, and the exhausts have not rusted through. A complete RD 400 with correct numbers and original parts is usually a better base than a pretty bike with an unknown rebuild history.

Before you buy
What to check before buying
- Check crankshaft, seals and cylinders for air leaks, noise and uneven compression.
- Check oil injection, carburettors and ignition; incorrect set-up can damage pistons.
- Inspect exhausts, frame and spoked wheels for corrosion and concealed welding.
- Check calipers, master cylinder and hoses for seizure or age-related deterioration.
