It has a truck engine and more than five times the grunt of the world's fastest bike, says Sean O'Grady

Your support makes all the difference.This is the love of 44-year-old engineer Nick Argyle's life: it is the Rapom V8. It is also, I am told, the most powerful motorcycle in Britain - and it runs on pure alcohol. Hic!
However, despite its renewable power source, it isn't that friendly to the environment. I am sorry to say that it can only manage some four miles to the gallon. Maybe that's one reason why this motorbike is only used on the roads for a 10-mile journey to a local drag-racing strip.
It is, nevertheless, fully street-legal so, theoretically, you could drive the Rapom V8 as far as and as fast as you like - cash, law and skill permitting. How fast? Thanks to traction control, it'll easily do 0-60mph in under three seconds and from a standing start to a quarter of a mile in under seven seconds.
The bike is an impressive piece of kit, whichever way you look at it. Powering it is an awesome 8.2-litre supercharged V8 truck engine that develops 1,000bhp - equivalent to a Bugatti Veyron or five Mini Cooper engines put together. The unit is more often to be found in Chrysler or Dodge trucks, and is sourced from their parts division, Mopar. (Rapom is Mopar backwards, in case you hadn't realised.)
This monster bike is more than five times as powerful as Kawasaki's ZZR-1400, the world's fastest production motorcycle. The Rapom certainly goes well, with that sort of power available with a twist of the wrist. It tips the scales at more than 1,000lb and features a super-long chassis in order to stop it flipping under hard acceleration. Some of us feel like falling over just looking at it.
It was created in a small garage in the Cotswolds, its conception spawned from an unusual marriage of convenience and naivety, says its builder. After selling the chassis of his monster truck (another hobby of his), Nick Argyle was searching for a smaller project.
He explains how the Rapom came about: "I didn't have the same workshop space I had when I built the truck. I only had the house garage, so it had to be a bike.
"I was going to buy a new engine for the project, but my wife told me to use the one that was still in a garage - that monster truck engine. Despite its size, I thought, why not?"
The remarkable Rapom V8 will make its public show debut on the Harrison Billet stand (S71) at the MCN London Motorcycle Show at ExCeL from 1 to 4 February.
