Not sure mine qualifies as extensively modified, certainly not cosmetically - they don't get any more standard!
Likewise the suspension is fully stock though I did have a rebuild on the front forks about ten years ago.
The motor has been tweaked though, with Stephens magic, HRC and Tyga bits in it...
Got a bit of history mind, having been ridden to the last ever GP250 race and photographed in the pits next to the last ever Championship winning bike!
Anyone beat that?
