Building the World-First Supercharged Engine

Building this ultimate tough cycle has been a journey of passion, innovation, and dedication. The result is a motorcycle that stands out not only for its power and performance but also for its unique design and luxurious details. Whether you're a motorcycle enthusiast or simply appreciate fine engineering, this supercharged Harley-Davidson is a testament to what can be achieved when you dream big and strive for excellence.

Designing a World-First Supercharged Engine

The goal was clear: to design the ultimate supercharged engine. This hadn't been done in the world yet, and I was determined to be the first. What emerged was a designer 117-inch engine with a four and five-eighth inch stroke and a four-inch bore. This engine boasts a bucket load of torque, and the supercharger propels it into the high horsepower numbers.

Unmatched Performance and Smoothness

The result is a motorcycle that is smooth, fast, and unmatched in performance. There's no one in Australia building engines like this, and the procharger perfectly complements the engine's bore and stroke. I'm incredibly excited to announce that these engines are now available exclusively from APL Performance.

Exclusivity and High-Quality Components

This motor was designed for one purpose: to create the fastest, most powerful street bike in Australia. These are specially ordered parts, exclusive to APL Performance. The motor includes roller rockered S&S components, rolling sends covers, renegade wheels, highlighted guards, racing suspension components, JD shocks, and gold valves in the forks.

Attention to Detail: The Gold Fleck and Diamonds

One of the standout features is the 74-carat gold fleck, which truly picks up the diamonds and gold in the tank. This bike deserves nothing less than the gold tough cycle badge, with $20,000 worth of diamonds and gold embedded in the tank. This is the ultimate tough cycle, and it had to be badged in gold and diamonds.

Custom Superchargers: A Personal Touch

You might think you can buy this supercharger off the shelf, but Walt over at Procharger will tell you there's only one person who customizes blowers like this, and that's me. It's been an honour to build this bike for one of my best mates, Pete, who's always been there for me.

APL Performance: Pushing Boundaries

APL Performance is about building the best Harley-Davidsons in the world and enhancing them to a level that defies imagination, something you can't get from dealers. It's something I'm proud to do here at APL Performance in Sydney, Australia.
