Vehicle Information
Honda CB100 Motorcycle - Street (1970-1973)
The Honda CB100, produced from 1970 to 1973, is a lightweight and accessible motorcycle. It features a consistent 99 cc air-cooled, single-cylinder, four-stroke OHC engine, paired with a 5-speed transmission and chain final drive. Horsepower generally ranged from 11.5 to 12 HP across these years. The CB100 was offered in "K" series trims (K0, K1, K2, K3), which primarily indicated model year updates and cosmetic variations rather than significant mechanical changes. Each K-series iteration brought minor aesthetic adjustments, such as new color schemes, changes to side cover emblems, and variations in chrome trim or headlight shell colors. The core mechanical architecture remained unchanged throughout the 1970-1973 period. Q: How do I know which CB100 model I have?
A: The Honda CB100 was produced in K-series trims (K0, K1, K2, K3) from 1970 to 1973. Please use our year and edition selector to find parts specific to your motorcycle.
