Nice - I have the same set up on my 749R trackbike (with the very rare ProTwins seat pad like you have). GLWS.
HaHa.. Yep that's where it came from, it was the replacement on my track bike after I got wiped out at Donnington, 3 or 4 laps round brands and never got used again Cheers
Cheers, it will soon be attached to one of Sev's bikes, not much left to go of the 999 now, complete set of wheels with new tyres and the Ali sub-frame, the 05 swing arm most likely up for sale in next few weeks
