• One of 19 Monotrack frames produced for the H1/H2 engine • Fewer than 30,000 miles • Less than one hour on complete engine rebuild completed in 2013 Following the lead of widely known and admired outfits such as Dunstall, Seeley and Rickman, reimagining and re-engineering factory-stock motorcycles, Dan Hanebrink of Costa Mesa, California was the engineer-founder of Monotrack Engineering. Monotrack designed and built frames and accessories which it sold via a catalog for a limited range of then current factory-production bikes, sold either as a build-it-yourself fame kit or as a complete bike. Constructed using a new 1970 Kawasaki H1A Mach III triple, this particular bike was built in 1972 and was one of 19 such frames made; half of which used the 500 2-stroke triple and the other half the 750 triple. A recognized eccentric genius – he may be better known in the bicycle engineering field - Hanebrink was clearly fed up with the contemporary engineering of sport bikes and so was persuaded to design a number of one-offs that never made it to the production stage. Little is known of this bike's history after delivery by Monotrack Engineering to its first owner although the odometer reading of near 30,000 miles suggest it was greatly enjoyed. The current vendor purchased the bike in 2012 from a Kawasaki triple collector in Florida who neither rode nor performed any servicing in the longer-than-a-decade period in which he kept the bike. This Kawasaki has never had any cosmetic restoration nor modification performed since it left Monotrack's hands. The current vendor reports that New York City's leading multi-cylinder 2-stroke expert (and former Honda motorcycle company engineer in Japan), Hidetaka Takasaki of Peak Point, performed a complete nut and bolt-up rebuild of the H1's engine, including a new crankshaft, seals, rods, pistons, rings and bearings, which he began in 2013 and completed approximately 12 months later. The motor has logged under an hour of total run time in the years since. Thus, on offer is a very rare 1970s icon that carries the patina of its origins yet its heart is virtually new. The Monotrack frame takes the 'instant whip' out the Kawasaki triple. And that's mighty cool.
