The Viper V-10-powered motorcycle is the Tomahawk Dodge that was never made

The Viper V-10 Dodge Tomahawk motorcycle concept made quite an impression at its 2003 Detroit Auto Show release, but surprisingly it never went into production. However, a motorcycle mechanic liked the idea so much that he built his own Viper V-10-powered bike.

Located in the UK, Allen Milliard built this crazy machine in a shed in 2009 and still uses it regularly. In a recent video, Millyard maintains some routine bikes in preparation for its MOT, the annual inspection required for all vehicles on public roads in the UK.

The handmade motorcycle with its huge car engine passed its inspection, proving that it is not just a show-piece. The odometer actually shows 9,150 miles.

The 8.0-liter V-10 is derived from a Dodge Viper GTS, and is estimated to produce around 500 hp. The engine also weighs 750 pounds, which is responsible for most of the 1,389-pound motorcycles.

The size of the engine also made a standard motorcycle frame invalid, so Milliard created two subframes that bolt on the front and rear of the engine. That design also leaves no room for a conventional transmission, but the V-10 has so much torque that multiple gears are not required, Milliard claimed.

Millyard can also rotate the rear wheel sprocket for different top speeds, from 160 mph to the claimed 270 mph. The bike, in the hands of motorcycle journalist Bruce Dane, crashed at a speed of 200 miles per hour at the proving ground in Bruntingthorpe.

Although it does not improve performance, an alternative ECU map adds extra fuel, creating loud backfiring from the exhaust.

There are several videos on Milliard’s YouTube channel that document the construction of this motorcycle. Check them out for more details on this viper-powered machine.
