Z Factor RS-534 Gen 2 M8 Camshaft

Z Factor is a joint effort between Fuel Moto and Zipper's Performance Products combining the strengths of both companies in engine R&D, testing, & tuning as well as OEM level manufacturing. This relationship allows for "farm to table" products, as we are able to control all aspects of product development and manufacturing from concept to the finish line. The Z Factor 534 was derived thru a program of extensive testing, including modeling/simulation, dyno testing & real world validation. 

The Z Factor 534 grind has been developed specifically for the Harley Davidson Milwaukee-8 Gen 2 engines, it works excellent in both 117 and 121HO engines. It's designed as a very flexible pattern, the 534 not only only loves the extra compression of the "HO" CVO 121 ST engine, its also an extremely strong performer in the 117 bikes. The Z Factor 534 makes especially broad power, with an emphasis on strong mid-range hit, quick acceleration, & very strong horsepower; all while providing great low RPM torque. Very aggressive idle.

• also works in first gen M8 engines (requires hi-lift valve springs)
