Shimizu Cycle Eight-Four Racing-Modified '06
With its single round headlamp and lack of an aerodynamic fairing, the Shimizu Eight-Four street bike served as a modern take on classic Japanese motorcycles from the 1970s. This special racing version, itself taking after racing bikes from the same decade, has been turned into a pure competition machine through extensive modification and tuning.

While the aluminum block remains stock, the engine uses performance-spec internals, including a machined crankshaft and more aggressive cams. The pistons and conrods, despite being of the same forged construction as the stock pistons, use a specialized racing-oriented design, and the stock cylinder head has been modified for better flow. The radiator, airbox, and exhaust mufflers have also been replaced.

Numerous modifications have also been made to the bike itself. A total of 18 kg (40 lb) has been shed thanks to lightweight body panels and wheels, as well as the removal of unnecessary components, such as the lights and passenger seat. While the street manners of the Eight-Four have all but been abandoned, the resulting motorcycle is one that undoubtedly punches above its weight.
