In a time when bikes with wild out designs get more attention than those with classic appeal, there's something very refreshing about a clean build with a black on black look. This 1978 Honda CB750 by Clockwork Motorcycles is a beautiful case-in-point, built by the shop's Samuel Guertin for a client that first brought him the bike in more than questionable health. From not being able to run and missing more than a few key pieces, the Montreal-based shop proceeded to strip the bike and rebuild it from the ground up. A 836cc Wiseco big-bore kit, SuperFlow valves, Beehive racing springs, heavy duty studs and a performance camshaft now provide motivation while a polished black frame free of any extraneous trimmings gives the CB750 clean lines and a slim proportion. A custom black leather seat by New Church Moto matches the leather-wrapped grips, shift-lever, and kick starter, while the stock oil and fuel tanks are among the few items mostly left intact, save for a custom Clockwork tag. Finished with a keyless ignition, a set of mini gauges, and LED lights, the build was marked complete as the glossy, satin, and matte black paint dried.
