Back in 1976, after the original Harley-Davidson engine's early demise, a mechanical engineer from Santa Barbara decided to install the sportiest, yet most reliable, motorcycle engine available on the market at that time: the legendary Honda 750-Four! Air-cooled like the Harley, it features an overhead camshaft, is fed by four separate Kei*hin carburetors, and puts out a very healthy 67 hp at 8000rpm. Coupled to Honda's bullet-proof 5-speed transmission, it allows for relaxed high-speed cruising way above any legal speed limit.
