Spares/Parts For Triumph 1958-69 Unit Twin Models

The Triumph Unit Twins were a popular model, not too big and not too small! In production for nearly twenty years there’s still a lot of these classic bikes around. Whether you’ve got a 350 or 500 unit Triumph, we’ve got the spares to keep her on the road.

This section is for 1958 models up to 1969, including the Tiger 90, 3TA and 5TA and the versatile T100. Use Triumph part numbers to find the parts you need or browse our catalogue pages, complete with exploded diagrams. From replacing your control cables to a complete engine overhaul, finding that missing gearbox bush or replacing a 6v headlamp bulb, we stock it! Give our staff a call or email if you get stuck, we’ve been working with British motorbikes since 1976 and more than happy to help.
