A very popular grind and power favorite for many engine builders of hopped up modified engines with added compression and a great bolt in choice for higher compression 103 Twin Cooled Models. The RS575 is a great cam if you need a bolt-in now, with serious plans on upgrading for more compression or increased flow in the near future.
This cam is most impressive when used with high flowing heads in a compression range of 10.2-10.8:1 compression, yielding a superior balanced torque and horsep ower curve. This is one of the most powerful mid lift cams on the market for a Twin Cam® engine.
The RS575 develops a good balanced power curve with “severe” acceleration. The proprietary profile design ensures maximum valve train acceleration, which gives the rider a very free-revving experience that begs for more throttle.
