About the Honda SL100
Parts for bringing a small Honda trail bike back into regular use.
The SL100 paired a four-stroke engine and five-speed gearbox with a double-cradle frame suited to trail use. This guide focuses on the 1970–1973 carburetor, engine-sealing, front-brake and clutch applications for an SL100 restoration.
Build the restoration order one assembly at a time
For a restoration, identify the carburetor before choosing its rebuild kit, then plan engine sealing around the joints being opened. The linked carburetor kit, gasket set, front shoes and steel clutch plate each list SL100 1970–1973. Shared CB100, CL100 or XL100 entries on a product apply to that item, not every part of the bike.

Identify your motorcycle before orderingSL100 identification checklist
Check front-wheel history when identifying chassis parts. Cycle World’s 1970 test SL100 had a distributor-fitted 21-inch front wheel in place of the standard 19-inch wheel. That test-bike modification is not a factory specification for every SL100.
Keep the bike’s identity and the details of the assembly being repaired together.
- Copy the complete frame and engine markings; preserve any model-series information.
- Photograph the carburetor body marking and the old bowl gasket before ordering.
- For chassis work, compare the installed brake assembly or fork dimensions directly.
