About the Honda C70 and Passport
Choose the engine gasket generation, then match brakes and clutch parts.
A C70 Passport restoration can involve engine resealing, drum-brake service and individual clutch components. The Passport name is useful for identifying the bike, but the repair still turns on its year and fitted engine or hubs. In this collection, the clearest engine-parts distinction is between gasket sets ending at 1981 and starting at 1982.
A 1981 and a 1982 C70 need different gasket-set checks
The early engine gasket set lists C70 1970–1981; the later set lists 1982–1993. For a Passport, use its own year and engine identity rather than treating that longer catalog range as a production history. Front and rear shoes have separate applications, and the clutch plates below preserve the stated gaps in their year coverage.
Know your model before choosing partsC70 model and repair differences
1970–1981 listed application
Early engine gasket set
The early set lists C70 through 1981.
Parts checkpoint: Use the installed engine’s identity and gasket layout.
1982–1993 listed application
Later engine gasket set
The later set starts at 1982. The longer range is the product’s stated application, not worldwide Passport production.
Parts checkpoint: Keep the 1981/1982 boundary when comparing the sets.
Brakes and clutch
Position and year gaps matter
The front brake-shoe listing includes C70 1972–1973 and 1980–1983; the rear example lists 1980–1983. Featured clutch plates list 1973 and 1982–1983.
Parts checkpoint: Do not fill missing years or treat front and rear applications as identical.
Frame, engine and component checksIdentify your C70 before ordering
Record the frame and engine markings, then compare the component being repaired. Include replacement-engine or chassis details if the motorcycle has been modified.
- Match the year and market to the C70 model documentation; record the engine marking separately.
- For gasket work, identify whether the engine matches the early or later listed application.
- For brake shoes, establish front or rear position and compare the original hub and shoe arrangement.
- For clutch plates, preserve the specified year gaps and identify plate type and stack position.
