About the Honda CB100
Identify the CB100, then build a model-specific restoration order.
Use this CB100 family page to identify the route for your motorcycle, then open the CB100K guide for its year-specific fuel, engine-sealing and front-brake comparisons. A CB100 family match alone does not select a part for every model year.
Continue to the CB100K repair guide
Compare CB100K parts by repair and model year. The K guide separates 1970–1972 fuel and engine applications from front brake shoes that also list 1973.
