About the Honda CT70
A small Honda with a major parts distinction: CT70K or manual-clutch CT70H.
Honda’s CT70 family uses a compact air-cooled four-stroke engine. In Honda’s early CT70/CT70H service specifications, the CT70 has a three-speed transmission and centrifugal automatic clutch, while the H uses a four-speed transmission and a hand-operated clutch.
Start with the clutch and transmission
Those differences matter most when choosing clutch and engine service parts. Our CT70K and CT70H collections also carry different carburetor, ignition and chassis applications. A product listing for one version must explicitly include the other before it is treated as shared fitment.
Know your motorcycle before orderingHonda CT70 model and year differences
The clutch distinction is a practical first check. Confirm the full model and year before selecting parts from either collection.

Use the complete identifiers and the correct model-year documentation. Check the engine and chassis separately when parts have been exchanged.
- Model and year: Record the complete frame stamping and confirm the exact year and market designation.
- Clutch controls: Identify a hand-operated clutch and the fitted transmission. Use the engine markings as well if the bike has been converted.
- Ignition: Check whether the original points arrangement remains fitted before choosing points or a condenser.
- Carburetor and brakes: Identify the carburetor body and the actual brake hub. Match a front-brake listing to the front wheel, not either end by assumption.
