This 1974 Yamaha MX80 is being wrecked at Derrimut. It’s an even smaller, earlier minicross bike than the MX100 – a twin-shock two-stroke built for junior riders in the early days of Yamaha’s motocross range, with drum brakes and a simplicity that later minicross bikes moved away from as the class developed.
Parts off this MX80
- Cylinder barrel, head and piston
- Carburettor and airbox
- Expansion chamber and silencer
- Gearbox internals and clutch assembly
- Forks and twin shocks
- Wheels, hubs and spokes
- Front and rear drum brake assemblies
- Plastics, fuel tank and seat
Early-70s Yamaha minicross bikes are genuinely scarce now, and this is exactly the kind of donor that keeps a vintage restoration project moving when dealer parts simply don’t exist anymore. Collectors and vintage racing clubs are the main buyers we see for parts off a bike this old, usually chasing a single hard-to-find item.
