Some of you may find it hard to believe this beauty is the work of a solo builder.
A little while back, we covered one of HB-Custom's most notable undertakings, namely a Honda NX650 Dominator that seemed fully prepared for some off-road action. The author behind that fascinating exploit is none other than the German workshop’s solo mastermind, Holger Breuer.
It goes without saying that this fellow is a genuine master in his line of business, having amazed the bespoke motorcycle realm with his one-off marvels on several occasions. Today, we’ll be diving in for a thorough analysis of his accomplishments on a cafe racer-style 1993 Honda CB750 that manages to look the business.
In stock form, the bike’s four-stroke 747cc inline-four powerplant houses a compression ratio of 9.3:1, sixteen valves, and four Keihin carbs with 34-mm (1.34-inch) throttle bodies. When the tachometer reaches optimal rpm, the engine generates 75 hp and 47 pound-feet (64 Nm) of torque, channeled to a chain final drive by a five-speed transmission. This results in a quarter-mile time of 12.4 seconds.
Right, let’s get to the point. Breuer kicked things off by tasking Old School Superbikes’ Ingo Wrubel with extracting as much power as possible from the machine’s four-cylinder fiend. As such, a premium set of Mikuni carburetors and K&N air filters replace the standard items, joined by a four-into-one aftermarket exhaust system at the other end of the combustion cycle.
Handling improvements are accomplished thanks to Wilbers fork internals, dual Ohlins shock absorbers, and top-shelf brake rotors developed by Brembo. With these goodies in place, Holger turned his attention to the bodywork department, where he installed a BMW R nineT Racer’s repurposed front fairing and a removable tail unit that sits atop a custom subframe.
Each and every standard lighting component was discarded to make room for LED alternatives, while the cockpit received Gilles Tooling clip-ons and a selection of Motogadget modules, including a digital speedometer, bar-end turn signalsm and fresh grips. At the other end, the creature's clip-on handlebars are appropriately complemented by LSL rear-mounted foot pegs.
