Hi Guys, just joined the list. I've recently bought an '87 model with only 22000KMs (Italian import) on the clock,it's in excellent condition and i must admit that i only bought it for the higher riding position and the fact that i really like thumpers.Off road riding's not very practical around here. I'm very interested in Supermoto (Super TT ?) bikes and am looking into the possibility of swapping to 17" rims alround and a bigger front brake. Does anyone on the list have any experience with such a conversion using either alloy or spoked wheels.. I'm also after a bigger front brake disc and bracket to move the caliper to suit. It may be that this will be uneconomical but it's worth asking -- Andy - Southampton,UK
