🔥 The APE/CR 515 continues to deliver.

This 2021 Road Glide fitted with a Screamin’ Eagle 131 received the full treatment from the team at Central Coast Harley-Davidson, featuring our APE/CR 515 camshaft, CNC ported 68mm intake and throttle body, TBR Turnout exhaust, and custom dyno calibration.

The result? A strong, responsive 131ci package that delivers exactly what a big-inch touring bike should — serious torque and horsepower right through the rev range.

154Hp / 165Tq 💪

Nice work by Master Tech Dan and the team 👏

If you’re running a 131 and looking for more from your combination, the APE/CR 515 is proving to be a very effective upgrade 🦍🦅

The turbo boys have been showing off their two-step flames lately… Respectfully, those are pilot lights 🔥

Meanwhile, Sam’s 131” is out here trying to burn the workshop down 🤣🔥🚒

Have a listen to this thing 😎

🔥 APE/CR 484 Magnum Cams - BACK IN STOCK 🔥

It’s been a bit of a wait on these… so firstly, thank you all for your patience.

The APE/Cycle-Rama, Inc. CR484 Magnum cam has well and truly proven itself as the go-to option for the Gen 2 Factory 117” platform 👌

Take a look at the graphs attached 😅📈

Phenomenal performance from a very simple, cost-effective combination.

Both bikes are running our basic APE cam package featuring the CR484 Magnum cam, while retaining:
• Stock throttle body
• Stock inlet manifold
• Stock injectors
• Freedom exhaust systems
• Screamin’ Eagle Extreme air cleaners
• Tuned calibration

Simple combinations, proven results… and serious gains in both horsepower & torque 🔥🚀

Huge results from our New Zealand distributor Road and Sport Harley Davidson 🇳🇿🔥

The APE/CR485 continues to deliver across a huge range of combinations, and this Stage 2 114” build is another perfect example 👌

135HP & 132ft/lbs from a simple, well thought-out combo with proper dyno tuning. Results speak for themselves 😎🚀

Out at Benaraby Raceway with the Talon Fat Boy prototype 😎🔥

APE Talon Fat Boy - 10.8 @ 120mph!!

4 consecutive 10-second passes from a factory 117” Fat Boy with our basic APE cam package, exhaust & tune.

With so much conjecture around dyno numbers these days, this is how you back up your work 👊 Real world results, on track, repeatable. There is only a few in the industry that are willing to do the same.

For anyone considering a Talon Fat Boy… you’re looking at a genuine 10-second street bike straight off the showroom floor 🦍🚀
