High Lift Cams by Zippers Performance
If anyone ever tells you “The ___ Cam is the best/only cam you should use” without knowing the specifics of your build then you need to talk to somebody else.
When you dive into the technical side of how different cam grinds work in relation to your cylinders, lifters, springs and rockers, it can be overwhelming. However, the end results of getting the right grind for your bike and your riding style, it’s well worth it.
Note: We don’t expect you to be an expert in this area. This is why we have technical experts on the phones here at Rollies to ensure you get the best results and value for money with your performance part upgrades. Give us a call during office hours for expert advice and a quote.
