When Schaefer's wife, Helen, tries to dish up tea at her Horspath home, more often than not she has to jostle with her bike-mad husband for space on the kitchen table.

Schaefer on board his custom Hayabusa

He uses the table as his workbench to mould the most amazing custom motorcycles. And he is quick to point out that he is not an engineer or mechanic. All his skills have been self taught over the years.

His latest creation - which he says is never planned, they just evolve - is a drag-style conversion of a standard Suzuki GSX1300R Hayabusa.

So good is it, that shortly after finishing the gleaming, shocking green show machine, it was whisked off to take pride of place on the Streetfighter Extreme stand at the NEC's International Motorcycle Show last November.

It had taken him three years to build.

Besides shelling out for the standard Hayabusa, Schaefer had to lash out around £20,000 on a huge list of replacement and custom-made parts, even though he has some backing from Goodridge, the hose specialist firm. What it has bought him is a show winner.

For those who want to see it in the flesh, it will next be paraded at the Streetfighter Show, Shefield, on April 3 and 4.

But the bike is not just for show. The modifications have also jacked up the standard bike's 150bhp - and I can say from experience that was already more than enough to gain warp speed - up to between 230 - 320bhp. The variation all depends on how high the turbo boost is turned up.

And Schaefer plans to put this to the test at the Judgement Day meeting of the 200mph Club at the RAF Woodbridge test track on May 15 and 16.

He hopes to improve on his last outing at Santapod, the famous drag track in north Bedfordshire. There, he dropped the clutch and 9.4 seconds later hit 147mph over the quarter-mile distance. Top speed so far, simply guaged by the speedo and without the turbo, is 204mph.

Sadly Schaefer's last custom bike - a brilliant yellow Suzuki GSX1127R - was stolen.

That took four years to complete and won a stack of show awards before the evil thieves got their hands on it.

It took eight months to track down the bike, but all that remained was a collection of parts in boxes.

Although Schaefer has more projects in the pipeline, finding the time could now be more of a problem, as just five months ago he launched a new venture - the Jam Factory Cafe and Takeaway. And guess what customers he is eager to cater for? Bikers of course!
