THE BIKES...
FASCINATING 104/106 FACT (HMM): We tried a turbocharger on WR104 in 2005. It was rubbish.

2004-on
WR104 and 206 are near-identical C90s used in charity supermotoped races at RAF Wittering. WR104 was our first-ever Moped Mayhem bike, but was replaced after one race. We braced the frame and found we had a near-perfect supermotoped. The popularity of the bike with people looking for guest rides led us to build a second one, WR106, in 2006. Both bikes cost less than £200 to build and can be made in around a weekend.

The high point of the Wittering project came in 2007 when the two bikes finished third and fifth of 46 bikes with a pair of All-Star teams riding them. That's TonyH and Rucksack giving each other hell during the race.

A careful study showed how much gaffer tape we've used to cover the seats. A lot.
