Honda CB500K Parts (1971–1973) – OEM & Aftermarket Motorcycle Parts

Sort by

Looking for high-quality Honda CB500 parts? Whether you ride a 1971, 1972, or 1973 CB500 Four, this collection includes everything you need to restore, maintain, or customize one of Honda’s most important middleweight four-cylinder motorcycles.

The Honda CB500 Four was introduced in the early 1970s and made its public debut at the London Racing and Sporting Motorcycle Show. Styled similarly to the legendary CB750 but lighter and more compact, the CB500 was Honda’s answer to riders who wanted four-cylinder performance without the bulk. Powered by a 498cc SOHC inline-four engine, Honda claimed 50 horsepower and a top speed of around 115 mph, impressive figures for the era.

After establishing four-cylinder dominance with the CB750, Honda successfully translated that engineering into a smaller, more agile package with the CB500. The result was a motorcycle known for smooth power delivery, excellent balance, and everyday rideability — qualities that have earned it lasting respect among vintage Honda enthusiasts, restorers, and custom builders.
