Pro bike: Britain’s fastest bike – Guy Martin’s custom Rourke

As ridden at 112mph by the nation's favourite Isle of Man TT racer

Exhibited among products from Hope Technology at this year’s Core Bike Show was this record-breaking land speed bike. Still dirty from its record-breaking venture on the sands of Pendine, this is officially the fastest bike in Britain. We take a closer look at Guy Martin’s custom Rourke.


For those who aren’t already familiar with this machine, this was the bike that Isle of Man TT racer Guy Martin pedalled to 112.94mph while travelling in the slipstream of a 1,000hp racing truck, breaking the British record for outright speed on a bicycle in the process.

The frame is the work of UK-based custom builder Jason Rourke of Rourke Handbuilt Cycles, constructed from Reynolds 853 tubing it features a unique fixed, twin-chain drivetrain complete with two custom 60-tooth chainrings.

The succesful record attempt took place at Pendine Sands, South Wales, and was one of several that Guy attempted to break during his Speed television series that recently aired on Channel 4. Take a flick through our image gallery for more details on this record-breaking rig.
