V-Rod Camshaft Specifications

Special Notes on V-Rod cam specs

bullet

There is no accepted standard for measuring duration on V-rod cams. The table provides the manufacturers lift at which duration was measured.

bullet

It can be very difficult to compare cams measured at different durations. Even minor changes in lift can have a significant impact on the duration. Grind profiles can vary greatly and provide major differences in how fast the valve is lifted .

bullet

Intake and Exhaust grinds are generally listed separately. You can "mix and match" the various grinds to create your own combination.

bullet

Opening and closing degrees are generally not provided. Durations are provided at the measured lift. By altering cam timing, you can create your own specs based on the needs of your engine.
