Dodge Viper V10 engine motorcycle listed for auction for over 700 thousand reais

Goal and Difference from Prototypes

Unlike the Tomahawk, which was sold as static 'automotive sculptures' for over half a million dollars each, the British engineer aimed to create a vehicle that would be usable, reasonably comfortable (as much as possible), and fully road-certified.

Engineering Solutions of the Design

Mounting an engine weighing over 300 kg onto two wheels required ingenious solutions. The motorcycle lacks a traditional frame; instead, the main structural element is the V10 iron and aluminum block from the Viper itself. The front guide is supported by a tubular subframe, and the rear monoshock is bolted directly to the transmission casing.

Powerplant and Transmission

Since the motorcycle is equipped with a powerful 8-liter engine producing 500 horsepower and 72.5 kg·m of torque, a gearbox is unnecessary. It operates in a single gear. The theoretical maximum speed is regulated by replacing the secondary drive sprocket with a chain, allowing speeds from 250 km/h to over 430 km/h.

Mechanical Features and Safety

The original cast Viper flywheel was so heavy that the dynamic torque almost tipped the rider upon initial startup. Millard had to fabricate an aluminum replacement to reduce this effect. Since no motorcycle suspension in the world could handle a total weight exceeding 600 kg, the creator fashioned the front forks using components from JCB excavator hydraulic cylinders. The exhaust system was thermally insulated with ceramic plates similar to those used in NASA space buses.

Achievements and Future Plans

The motorcycle was completed and registered in 2009. That same year, in official tests by the British magazine Motorcycle News, it reached a real top speed of 333.2 km/h without a fairing. In 2023, Allen Millard and television presenter Henry Cole entered the Guinness Book of Records, achieving a speed of 295 km/h together on this motorcycle. Despite its enormous weight and excessive fuel consumption, the odometer shows over 14,500 kilometers traveled. The creator rode it throughout the United Kingdom and even completed a lap of the legendary Isle of Man TT course. Now, the engineer has decided to pass on this relic, stating that he no longer wants to prove anything with this motorcycle, as it takes up a lot of space and requires constant maintenance. The money from the sale will go towards funding his next invention in his garage.
