Fierce performing camshaft for an array of engines sizes, large displacement 103in., 110in. and 124in. engines looking for a superior torque band with excellent horsepower gains in heavy bikes (2,200 - 6,250 rpm).

Smaller high revving displacement 95in. style engines in lighter bikes looking to twist the throttle and tap into some horsepower (2,500 - 6,800 rpm).

Large displacements respond well to increased compression ratio and smaller displacements will require it.

594 cams require high performance valve springs, pushrods, lifters, carburetor and or throttle body work, performance exhaust, intake and clutch.
