S&S 540 Torque Cam for Big Bore M8 Models

The S&S 540 Torque Cam comes on more like a freight train than a rocket. That’s a good way to roll if you’re riding a fully-loaded bagger. Big horsepower numbers are the status symbol of a performance engine. However, more often than not, the bolstered torque spec is what you really feel when riding it.

This is particularly relevant for the heavy touring machines as it’s torque that rockets you onto the highway and it’s definitely torque that lets you effortlessly push a loaded bagger around slower traffic. With that in mind, S&S Cycle created the 540 cam for M8 powered bikes.

The 540 is designed to work with their 124” and 128” big bore kits and produce stump pulling torque down low in the RPM range as well as maintain respectable horsepower numbers. Available in gear or chain drive and in a complete cam chest kit with pump, plate, pushrods and tappets. Check out their dyno charts for the hard numbers (130+ lb ft and on a conservative 124-inch build). For more info on the S&S 540 Torque Cam hit up S&S Cycle here.
