Hyper Pro racer

Let me introduce you to the Aussie Racing. The aussie racing is an Australian motor racing category. Essentially a motorcycle powered Sports car class, it was created by former Touring car racer Phil Ward, influenced by the American Legends category.
In 2009 the series made the transition from running at V8 Supercar events to run on the Shannons Nationals Motor Racing Championships program..

Jon Crooke a guy who worked ten years to develope the Hyper PRO Racer, a so-called "Superkart" delivering massive power and minimum weight. Using a Yamaha 450 WR four-stroke motorcycle engine runing through a five-speed sequential gearbox, the Hyper PRO weighs just 352 pounds minus the weight of the driver. That isn't too much more than the enduro bike the engine is taken from. The weight savings respect of the superkart's spaceframe, which also acts as an FIA-approved roll cage. Instead of building a frame that accessories would be mounted to with brackets, the superkart's externals are mounted directly to a highly designed and minimalist chassis frame without additional hardware. Those externals include Ohlins aluminum-bodied race shocks, four-wheel cross-vented disc brakes with billet four-pot aluminum brake calipers, according to Hyper PRO, the result is a track runner that can lap a little faster than an Aussie racing car (not a V8 Supercar), a little slower than a GT Production car. But it beats them all for price: the track day Racer S is $29,500 Australian , the hillclimb Racer R is $35,500. check out the video...
