Well register rolling along the earliest bike is 98 and the oldest 599. When I get the list bigger I'll post it. Warning to Scura owners I went up the road with mine last week, thankfully I was only doing 20mph, a small slide can be very costly. I was wearing a new Guzzi leather jacket at the time the real surprise is that it worked, the leather looks like a piece of shit but it took more abrasion than I thought it would. Still a bit sore, cause of accident and this is one to watchout for a large perspex sign lying in the road, did'nt see it as following traffic, an instant off!
