Koso Camshaft – Honda Grom & Monkey
- 240 Degree Performance Camshaft
The Koso 240 Degree Performance Camshaft (MM623002) will give you great results at high RPM. This camshaft can be used with a stock engine, but will even give better results with the Koso 170cc big bore kit. Made from quality material for longer durability, the Koso GROM & MONKEYcamshaft is a clever choice!
Performance cams typically have a duration ranging from 220 up to 280 degrees or higher. The higher the duration, the rougher the idle and the higher the camÃ¢â‚¬â„¢s power range on the RPM scale. A cam with a duration of 240 degrees or higher will typically produce the most power from 3,500 to 7,000 RPM.
