That bike was NOT a Service Honda,
although several Service 500AF's were being ridden that day by David Thorpe, Greg Hansen, Rob Herring ,and Luke Hill.
and had no issues at all! other than throwing big roost! ;)
Luke Hill is currently sitting second in the British 2 stroke Championships.
That broken bike , was a home built of a fast upcoming UK rider,
(I believe scott edenfield?)
whose father had contacted about buying a service bike previously ,
but decided to build there own.....
he dint get hurt ,is the main thing..
and i'm sure they went back and rethought how they should build it.
