Yamaha YZ80 Parts for repair and restoration
The Yamaha YZ80 is a small-displacement motocross bike. For 2002 Yamaha changed its 80 cc model to the YZ85, so engine parts and shared brake applications must be matched to the exact model and year.
Engine resealing
The Yamaha YZ80 engine gasket set fits 1985–1992 and is sold as a set.
Compare the engine family, openings and gasket-kit contents to the parts removed during teardown.
Steel clutch plates
These plain steel plates are separate from friction plates and are sold individually. Choose the 1986–1994 plate or the 1995–2001 plate by model year.
Keep the clutch-stack order and confirm plate thickness and tang pattern before assembly.
Front disc-brake pads
The front brake pad covers YZ80 1986–2001 and YZ85 2002–2005, replacing Yamaha OEM 1LR-W0046-00.
Sold individually; compare the pad shape and retaining hardware to the front caliper.
Choosing parts for your Yamaha YZ80
Use the model transition: Yamaha's 2002 release describes its 80 cc model becoming the YZ85 with an 85 cc engine. Treat YZ80 and YZ85 engine parts as different applications even where a brake part covers both names.
Choose clutch plates by year: the YZ80 steel-plate applications split at 1995: one is 1986–1994 and another is 1995–2001. These are individual steel drive plates, not a complete clutch pack.
Check part type and position: the gasket set fits YZ80 1985–1992, while the front brake pad fits YZ80 1986–2001 or YZ85 2002–2005. Match the engine or caliper and OEM reference before ordering.
Building a custom Yamaha YZ80?
For a café racer, tracker or other custom build, browse universal handlebars and grips and mirrors and adaptors. Check clamp diameter, mirror threads, cable reach and steering clearance; universal accessories may need modification on your motorcycle.
