The A.P.E. Power Plus Cam Kit is one of the best first performance upgrades for Harley-Davidson Milwaukee-Eight (M8) riders. It delivers sharper throttle response and stronger mid-range torque without the cost of a big bore build.

Taverner Motorsports supplies, installs and dyno tunes A.P.E. Power Plus Cam Kits in Bowen Hills, Brisbane, and ships Australia-wide. Suits 2017 to current M8 Touring and Softail models.

What Is the A.P.E. Power Plus Cam Kit?

The Power Plus Cam Kit is a complete camshaft upgrade package designed to give your M8 engine more attitude, stronger torque and sharper acceleration. Depending on your motorcycle and goals, cam options may include CR480, CR483, CR484, CR485 and newer A.P.E. cam profiles where suitable.
The package may include camshaft, cam bearing, high-capacity lifters, billet lifter cuffs, adjustable pushrods, cam install gasket kit, high-flow injectors and intake manifold components.

Is the Power Plus Cam Kit Right for You?

It's a great fit if you:
  • Want a noticeably stronger Harley without a full engine rebuild
  • Are ready to go beyond a Stage 1 intake and exhaust
  • Want a cost-effective Stage 2-style upgrade
  • May step up to an A.P.E. Stump Puller big bore later
What you'll feel on the road:
  • Sharper throttle response
  • More mid-range torque for overtaking
  • A choppier idle, depending on your cam
