The Dodge Tomahawk was a non-street legalconcept vehicle introduced by Dodge at the 2003 North American International Auto Show in Detroit, Michigan. Dodge's extraordinary claims of a top speed of 420 mph (680 km/h) were derided by experts in land speed records, and the Tomahawk never demonstrated a speed above 100 mph (160 km/h).
The Art Deco design was the work of Chrysler staff designer Mark Walters and featured the 500 hp (370 kW) 8.3-litre (510 cu in) V10SRT10 engine from the Dodge Viper. The vehicle has two front wheels and two rear wheels, making it a kind of motorized quadricycle rather than a typical motorcycle. The pairs of wheels move independently, allowing it to countersteer and lean in turns like a motorcycle.
Hand-built examples of the Tomahawk were offered for sale through the Neiman Marcus catalog at a price of US$ 555,000, and up to nine of them might have sold.Dodge emphasized that the bikes were "rolling sculptures" not intended to be ridden.
In 2008, MTT released the "Streetfighter," another jet-bike with a more powerful 420 hp (310 kW) engine.
Aprilia RSV 1000R Mille
The first RSV Mille (ME) was made from 1998 to 2000, the updated RSV Mille (RP) from 2001 to 2002 and the last update was made in 2003.
With a 998 cc 60-degree V-twin engine built by the Austrian company Rotax, the RSV Mille was the first large displacement motorcycle made by Aprilia that up to then had made up to 250cc engines. This same engine was used unmodified in the Tuono and in slightly modified form in the SL1000 Falco.
The Mille featured a type of slipper clutch, which worked by using a vacuum on a closed throttle from the inlet manifold to give the effect of slipper clutch, but only on a closed throttle.
