I've had an abba stand for 12 years or so and they're great, easy to use and when you change the bike just get a new set of adapters. The thing is that the mille and the haynes manual say 25mm of chain tension with the bike on a paddock stand, but with the abba every thing hangs uncompressed,so is that still correct? I mean, have I been running a tight chain for two years? The only thing is I haven't been that conscientious about it, a bit slack so to speak on the tensioning front, but if anyone has any ideas I'd be grateful. By the way I ha d a pair of Bridgestone S20's fitted a few days ago,so far they feel great, loads of dry grip and I'm waiting to see what they're like in the wet. They're supposed to be pretty good. The other thing is that a 190/50 doesn't catch the chain or the guard on a 2003 'R', though it is bloody close! Thanks.
