The Millyard Viper V10 is a one-off motorcycle capable of over 200 mph (320 km/h)[1] that was built by British engineer Allen Millyard. The motorcycle weighs 1,200 lb (540 kg), of which 700 lb (320 kg) is the 8-litre engine,[2] sourced from ebay, originally intended for a Dodge Viper, with the V10 cylinder configuration producing 500 bhp (370 kW) at 4,800rpm.[3]

A front subframe mounted to the engine carries the steering and suspension, with the front forks being crafted using hydraulic ram components with springs by Hagon. A rear subframe carries suspension created by using two monoshock units from the Yamaha R1 model.[1]

Millyard has stated that he aims to reach a top speed of 250 mph (400 km/h) with this bike.[1] In early speed tests, it surpassed 200 mph (320 km/h).[4] The bike has been clocked at a top speed of 207 mph (333 km/h) at the Bruntingthorpe Proving Ground.[5]

On 25 May 2023, rider Allen Millyard together with passenger, television presenter Henry Cole, claimed a world motorcycle speed-record, ratified by Guinness World Records at 183.50 mph (295.31 km/h), achieved with the pair riding "tandem" on the hand-made, road-legal machine, beating by two mph the previous record held by an American couple for over 10 years. The record was set using the 9,800 ft (3,000 m) long runway at Elvington Airfield, North Yorkshire, England, on 25 May 2023.[6][7][8]
