Honda CB model guide

Match the early CB125 application

Match CB125 (1970) explicitly. Do not select engine, ignition or fuel parts from a CB125S listing unless that product also names your twin-cylinder application. The LD05F cap is sold each. The synchronizer is a universal tool for two-carb setups; verify vacuum takeoff points and 5mm connections/adapters. No 1970 carburetor rebuild kit is featured because the available 48-1388 listing stops at 1969. Compare OEM references and dimensions where supplied, and check the listing for contents and quantity.

Fitment questions

Do CB125 twin and CB125S parts interchange? Only when the product explicitly lists your model and year. CB125 twins and CB125S singles are different applications; compare the fitted component and any listed dimensions before ordering.

Does an OEM reference mean the part is genuine Honda? Not by itself. Aftermarket parts can quote the Honda number they replace. Look for an explicit genuine Honda description if brand origin matters; “OEM-type” or “replaces OEM” does not identify the manufacturer.
