White Heat Street Custom Motorbike
“This street custom wasn't just a machine; it was a 'realisation', a potent blend of horsepower and artistry,” said Knackers.
ADAM, the quiet architect of Mainframe Custom Cycles (MCC), moved with an economy of motion that belied the intricate dance of his craft. He wasn’t one for grand pronouncements or a bustling social media presence. His reputation, instead, was etched in the flawless lines and thrumming power of the machines that rolled out of his workshop. A gentleman, as some would describe him, whose calm demeanour was as much a part of his signature as the bespoke frames he meticulously shaped.
Today, his focus was absolute, his gaze fixed on the near-complete street custom that dominated the centre of the shop. This wasn’t merely a bike; it was a symphony of meticulously sourced parts, a testament to a client’s trust, and Adam’s unwavering vision. The owner, Elias Thorne, had approached Adam with a concept, a whisper of a dream, and then stepped back, allowing the artist his space. There had been no deadlines hounding Adam, no anxious calls, just a quiet understanding that when it was ready, it would be perfect.
Adam ran a gloved hand over the sweeping arc of the frame. It began its life as a KraftTech Softail-styled chassis but Adam had subtly reshaped its destiny. The single, thick down-tube now carried an even more aggressive 40-degree rake, hinting at the beast within. And what a beast it is: a formidable 124-cubic-inch S&S engine, its three-figured potency promising a raw, untamed power. Feeding this heart was an E-series shorty carburetor, also from S&S, cloaked beneath a custom billet air-cleaner from Performance Machine — a sleek blend of gloss black and satin metal, a quiet statement of intent. The spent gasses would roar their farewell through flat-blackened Freedom exhaust pipes, a final flourish of defiance before vanishing into the ether. Every other component of this formidable power-plant, down to the first electronic ignition, bore the S&S mark.



The grunt generated by the engine was a force to be tamed, and Adam had orchestrated its transfer to the rear wheel with precision. First, the power flowed into a Trick Shift six-speed gearbox mounted on the right side. From there, it spilled into a RevTech open primary belt-drive; its 3.5-inch belt a mesmerising blur of controlled power. The final link in this chain was a RC Components Sprotor set — a brilliant integration of a four-spotter, chrome-billet caliper, rotor-pulley and belt, all working as one.
The front-end, a menacing blend of black and chrome, hailed from American Suspension. Its stopping power was equally impressive — a single-spotter caliper from the same manufacturer gripping the RC Components black and satin finished rim. This was shod with an Avon Cobra tyre ready to bite into the asphalt.
Here, Adam’s quiet genius revealed itself. Unlike many custom builds, he had elected to mount both front and rear brakes on the same side. This ingenious decision resulted in an incredibly clean, disc-free visual on the left, a subtle touch that spoke volumes of his commitment to aesthetics without compromising performance.


The ‘ET headlight’, a distinctive, almost alien eye, stood sentinel for the night duties, guiding the way forward. Steering was handled by custom-made bars from Custom Cycle Controls (CCC); their cables routed internally, unseen. CCC grips, levers, and billet mirrors completed the cockpit, an ergonomic masterpiece.
At the rear, the RC Components rim was a truly imposing presence: 10.5-inches wide and 18-inches in diameter, it cradled a truly fat 300/35R18 Avon tyre. This immense rubber worked in seamless tandem with the Progressive Suspension rear setup, ensuring a ride as smooth as it was powerful. The rear guard, originally from KraftTech, had been extensively modified by Adam to perfectly embrace the colossal tyre. The custom seat, a sleek form wrapped in black leather, was the comfort factor.
The stretched fuel and oil tanks, both elegant and functional, were further pieces from KraftTech. Resting points and gear change operation were provided by CCC forward controls, their polished surfaces reflecting the workshop lights. Mini LED indicators, discreet yet intensely bright, adorned the rear, while the front signals were cleverly integrated into the mirrors. The forward control unit itself was a finely crafted piece from Custom Chopper Works.



Then came the magic of the finish. The frame was meticulously prepped and painted in a luminous pearl white, a canvas awaiting its masterpiece. It was then transported to the legendary Mat Egan at Extreme Designs. Mat, with his own brand of quiet brilliance, laid down layers of House of Kolor glacier gold, interweaving it with subtle black and grey graphics. The entire composition was then outlined with audacious purple pinstripes, and finally, overlaid with gold and purple pinstripe overtones that danced and shimmered in the light. The result was breathtaking — a dynamic, elegant, yet undeniably aggressive colour scheme that perfectly complemented the motorbike’s powerful stance.
When Elias finally saw his ride, complete and gleaming under the fluorescent lights, a low whistle escaped his lips. He walked around it slowly, not touching, just absorbing every curve, every flash of colour, every intricate detail. The street custom wasn’t just a machine; it was a realisation, a potent blend of horsepower and artistry. Adam watched a rare, subtle curve of his lips, the only outward sign of his satisfaction.
The quiet man from Laverton had done it again. Another masterpiece rolled out of Mainframe Custom Cycles, destined not just for the cool department, but to enhance the very streets of Melbourne with its formidable, undeniable presence. It was more than a bike; it was a testament to the power of quiet dedication, a roaring monument built bolt-by-painstaking-bolt, by Adam, the gentleman architect of speed.
