We have been building performance engines for Harley-Davidson motorcycles for 15 years and have seen the need for Kits to suit the Riders needs not just a one size fits all approach.

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 🦍🚀

Very nice result from Simon at Jobson Motorsport with his personal 2025 Low Rider ST 👌🔥

We sent Simon down one of the T-MAN PERFORMANCE 117ST cams to test in the new Gen 2 platform - and safe to say, it delivered.

📈 137.6 HP
📈 146.98 TQ

🔧 Combo:
• 2025 FXLRST Stage 2
• SP Concepts 4.5” Power Flow Exhaust
• T-Man Performance 117ST Cam
• APE High Capacity Lifters
• APE Billet Tappet Cuffs
• APE Adjustable Pushrods
• Stock Throttle Body
• Stock Intake
• Stock Injectors
• Tuned via Dynojet PV3

Killer bolt-in package with smooth, usable power right across the curve 👊

Another example that these Gen 2 117’s respond incredibly well to the right camshaft combination - without needing an over-the-top setup 😏

CR470, APE/CR 484 & APE/CR 485… all under .500” lift, all producing 140+ HP SAE in the factory 117” Gen 2 M8 😮‍💨🔥

Might we add - two of these grinds were released well before the Gen 2 engines even hit the market.

We’re continuing to find that the proven cams which performed exceptionally well in the Gen 1 engine, perform just as well in the Gen 2… only now they’re producing even higher output 😉
