Guy Martin takes one of the riskiest motorcycle stunts of all time and super-sizes it in an attempt to set a Guinness World Record on the Wall of Death.

The feat was televised live on Channel 4 in the UK on March 28 and immediately certified as a Guinness World Record. A Wall of Death installation is a silo-shaped cylinder made of wooden planks, usually ranging from 20 to 36 feet in diameter. Motorcyclists traveling along the vertical wall of the silo at a typical speed of approx. 20 mph are held in place by centrifugal force. To reach the 60 mph Martin needed to achieve for a record, yet limit the g-force plying his body, the Wall of Death built for him featured a 387-ft. circumference.

Viewers saw Martin set the overall speed record on his own custom-built motorcycle, but to prepare for the live attempt, he used an Indian Scout supplied by Krazy Horse, an Indian Motorcycle dealership in Bury St Edmunds, UK.

Riding the Indian Scout, Martin hit 60.1 mph – an instant Guinness World Record – on his first attempt and reached a confirmed 70.33 mph on his second attempt. Then he switched to his own custom-built BSA R3 powered by aviation fuel. The result: 78.15 mph, the speed logged for the official Guinness World Record.
