About the Honda CT70K
A practical Trail 70 guide with separate float generations and front/rear brake routes.
The CT70K is associated with the three-speed, automatic-clutch Trail 70 layout. Honda’s early specifications distinguish it from the manual-clutch, four-speed CT70H. A replacement engine can change the service parts required even when the frame still carries a K identity.

The two float products cover different year groups and have visibly different shapes. Front and rear brake shoes have separate direct links. Engine-gasket and clutch-plate applications also end at different years, so the repair table keeps each range intact.
Choose the model and repairCT70K carburetor floats: early and later applications
| Linked float | Listed years | Selection detail |
|---|---|---|
| 1970–1975 CT70K carburetor float | 1970–1975 | Compare the two-lobed float shape, hinge and pin arrangement pictured. |
| 1978–1982 CT70K carburetor float | 1978–1982 | Compare the different float-body shape and valve-contact arrangement pictured. |
The two listings do not establish a 1976–1977 application. For those years or a replacement carburetor, send its body markings and a float photo for an exact match.
Frame, engine and fitted componentsHonda CT70K identification checklist
Use the complete identifiers and the correct model-year documentation. Check the engine and chassis separately when parts have been exchanged.
- Frame record: Confirm the complete model year and frame marking, rather than relying on paint, decals or a registration date alone.
- Installed engine: Record the engine number and whether the original automatic-clutch arrangement remains fitted.
- Clutch parts: Distinguish a single friction plate from a complete pack. Confirm plate quantity and any other worn parts separately.
- Front drum: Compare the fitted front hub, old shoes and stated front application before ordering brake parts.
