The A.P.E. Street Performer is the all-round Harley M8 package for riders who want serious horsepower and torque without losing smooth street manners. Available in 124ci and 128ci, it combines upgraded cylinder heads with a matched cam for broad power delivery and 150+ hp and torque potential on pump fuel.

Taverner Motorsports supplies, installs and dyno tunes the Street Performer at our Bowen Hills workshop in Brisbane, with Australia-wide shipping.

what is the A.P.E. Street Performer?

The Street Performer is A.P.E.'s all-rounder: stronger than the torque-focused Stump Puller at higher RPM, and smoother and more street-friendly than the Sneaky Pete or Silverback. It suits riders who want a big step up in power on a bike that's still easy to live with every day.

What's included:
  • 124ci or 128ci A.P.E. cylinders and forged pistons
  • Upgraded/ported cylinder heads
  • Cam profile
  • Valve train components, lifters, pushrods
  • Intake, injectors, gaskets and hardware
  • Oil pump requirement for 2017 to 2019 models, if applicable

Who Is the Street Performer Best For?

  • Riders who want 150+ hp and torque with smooth everyday manners
  • Road Glide, Street Glide and Softail riders who ride in traffic, on highways and on weekend runs
  • Riders who've outgrown a cam kit but don't want an aggressive race-style build
  • 114ci and 117ci M8 owners moving to 128ci
What you'll feel on the road:
  • Smooth, broad power across the rev range
  • Strong low-end torque with more top-end than the Stump Puller
