Discover the pinnacle of custom engineering: our final BMW masterpiece is now available for acquisition. This exceptional build showcases a dynamic pairing of 17" x 3.5" Excel Takasago rims at the front and 17" x 4.25" rims at the rear, all enveloped in high-performance Pirelli Diablo Rosso tires for unmatched traction and handling.

At the heart of its transformation is a bespoke Cognito Moto front conversion hub, flawlessly integrated with a 2011+ GSX-R600 inverted fork, complemented by custom-designed triple clamps. The braking system is a testament to our commitment to safety and performance, featuring GSX-R600 disc brakes paired with premium Brembo calipers and a master cylinder, ensuring responsive and reliable stopping power.

The rear setup is no less impressive, with a custom Cognito Moto disc conversion hub and a Brembo rear caliper. Powering this beauty is a fully rebuilt engine, enhanced with a Siebenrock 1000cc kit and 1000cc heads, upgraded with Kibblewhite springs, retainers, and valves for superior performance. The transmission has been meticulously rebuilt, featuring a new flywheel, clutch, and an EME starter, guaranteeing smooth and reliable power delivery.

Attention to detail is evident in every aspect, from the sleek engine profile achieved by an intake delete to the new Dellorto carbs with custom-made filtered velocity stacks. The exhaust system boasts new chrome headers and Cone Engineering quiet core mufflers, ensuring a sound as captivating as the bike itself.

Aesthetically, the motorcycle stuns with its freshly painted Porsche Aventurine Green tank, while the electrical system, powered by an M-Unit Blue MotoGadget, ensures seamless operation with push-button start, Biltwell Whiskey throttle, and M-Lock keyless ignition. The Motogadget Motoscope Pro gauge with gear selection detection, custom-made subframe with integrated LED taillight, and meticulously upholstered seat by New Church Moto elevate the bike's visual and functional appeal.

This build, documented on YouTube, started from a frame and engine (non-matching numbers) and was crafted from the ground up. It comes with a clean Virginia title, marking it as a 1972 BMW R75. This motorcycle is not just a means of transportation; it's a piece of art, offering an unparalleled riding experience for the discerning enthusiast.
