Honda CB650 Parts (1979–1982) – OEM & Aftermarket Motorcycle Parts

Looking for high-quality Honda CB650 parts? Whether you ride a late-1970s or early-1980s CB650, this collection includes everything you need to restore, maintain, or customize one of Honda’s most refined SOHC four-cylinder motorcycles.

The Honda CB650 was introduced as a middleweight four-cylinder motorcycle that combined the proven engineering of the CB550 with increased displacement and performance. Built on a lighter, more compact chassis derived from the CB550, the CB650 delivered performance comparable to contemporary DOHC 750cc motorcycles, thanks to its reduced weight and balanced handling. Early models shared components such as the frame and speedometer with the CB550, reinforcing the platform’s proven reliability.

Most notably, the CB650 became Honda’s final SOHC air-cooled inline-four engine, representing the culmination of Honda’s single overhead camshaft technology before the transition to DOHC designs. Smooth power delivery, excellent durability, and classic four-cylinder character made the CB650 a favorite among riders who wanted strong performance without the bulk of the larger CB versions.
