What does SOHC mean?
Single Overhead Camshaft (SOHC) is a valvetrain configuration where one camshaft, mounted in the cylinder head, controls both intake and exhaust valves. SOHC engines are simpler and lighter than DOHC designs.
While SOHC engines generally cannot rev as high as DOHC counterparts, they often deliver strong low-to-mid range torque, making them well-suited for commuters, naked bikes and cruisers. Honda's legendary CB series has used SOHC designs for decades.
How riders should use this term
Motorcycle terms are most useful when they help you understand real riding behavior. When you see SOHC on a spec page, treat it as one part of the full motorcycle package, not as a number or feature to judge alone.
- Compare the term against the motorcycle category and intended use.
- Check related specs such as weight, engine size, seat height, braking system and suspension.
- Use the comparison tool if two bikes look similar on paper.
