Dodge Tomahawk

The Tomahawk was a non-street legal concept vehicle introduced by Dodge at the 2003 North American International Auto Show in Detroit, Michigan. It had futuristic and unusual design, featuring the 500 horsepower (370 kW) 8.3-litre (510 cu in) V10 SRT10 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.  
Top speed


Dodge initially announced the top speed of the Tomahawk was estimated at 420 miles per hour (680 km/h), but later revised this downward to 300 miles per hour (480 km/h), and spokesmen did not answer questions on how this estimate was calculated.  Wolfgang Bernhard, Chrysler Group chief operating officer at the time, said in 2003 that no one had ridden the Tomahawk faster than 100 miles per hour (160 km/h).
Joe Teresi, of Easyriders magazine and owner of the world record setting motorcycle ridden by Dave Campos, said the top speed estimate must have been based only on horsepower and final drive ratio, and ignored the “critical factors” of frontal area, drag coefficient, and rolling resistance. Dodge declined offers to put the top speed claim to a test, and no one is known to have attempted to ride the Tomahawk to its maximum speed. Dodge spokesman David Elshoff said that “someday” the Tomahawk would be run at the Bonneville Speedway speed trials, but no such attempt was ever made. Campos was as skeptical as Teresi, saying he doubted the Tomahawk could exceed 200 miles per hour (320 km/h) because at high speeds, the rider would be “lifted right off the bike” without a streamliner fairing, and the four wheel steering would be a problem as well. Nonetheless, Campos wished Dodge luck, adding, “Let nothing but fear stand in your way.”  Phil Patton of the New York Times wrote, “In theory, the Tomahawk can blast from a standing start to 60 miles an hour in two and a half seconds and reach 300 miles an hour. In practice, since Evel Knievelretired, it’s hard to imagine anyone willing to prove it.”

The MTT Turbine Superbike

SUPERBIKE, also known as the Y2K Turbine SUPERBIKE, is the world’s second wheel-driven motorcycle powered by a turbine engine, created by Ted McIntyre of Marine Turbine Technologies Inc.


Reports of the MTT Turbine SUPERBIKE appeared as early as 1999 in a May issue of Cafe Racermagazine, but the production model was introduced in 2000.
Powered by a Rolls-Royce-Allison Model 250 turboshaft engine, producing 238 kW (320 hp), the motorcycle has a recorded top speed of 227 mph (370 km/h), with a price tag of US$175,000.00[1] It is recognized by Guinness World Records as the “Most powerful production motorcycle” and the “Most expensive production motorcycle.” Unlike some earlier jet-powered motorcycles, where a massive jet engine provided thrust to push the motorcycle, the turboshaft engine on this model drives the rear wheel via a two-speed gearbox. Riding the motorcycle is said to be somewhat tricky due to the inherent throttle lag in the engine, acceleration when letting off the throttle, and extreme length.


The engines used in the motorcycles are second-hand, having reached the FAA running time limit, after which they have to be rebuilt, regardless of condition. MTT can buy these engines for a much lower price than new engines and use them on surface vehicles without requiring FAA approval. To get around the problem of procuring the kerosene usually used in turbine engines, the engine of the bike is also able to use Diesel fuel, or even Jet A fuel.
In addition to the engine, there are other innovations incorporated into this bike, such as radar detector with laser scrambler, rear-mounted camera with LCD display, and an optional passenger seat.

Unlike other piston engine powered contemporary motorcycles (such as the Hayabusa), the 2001 and later models of the MTT Turbine SUPERBIKE do not have the 300 km/h speed limiting governors self-imposed by Japanese manufacturers.
In 2008, MTT released the “Streetfighter,” another jet-bike with a more powerful 420-horsepower (310 kW) engine.
