The NEW RS528 grind has been carefully designed and tested by Zipper’s engineering to yield the best possible riding experience while producing the most Torque and Horsepower for a bolt-in camshaft. It works exceptionally well with the new ride modes available in the 2024 Touring models. The new RS528 cam provides the performance advantage in power and throttle response right where you ride, with a “Drag bike” lope at idle and impressive exhaust note under load. The Red Shift RS528 bolt cam is designed specifically around the new Gen II cylinder head and induction system. It provides instant acceleration from below 2,000 RPM while pulling strong to 6,000. Made with a proprietary Red Shift Cams® ramp design, delivering quiet operation and long valve train life. The RS528 cam has been thoroughly tested with great results with the factory Touring header pipe with CAT with high flow mufflers as well as many aftermarket racing exhaust systems.
