Sadly I dithered too long over the horrible colour scheme on the special edition Mike Hailwood 796 and once I had decided I could live with it (and or change it) it was already sold. So onward OK I know a S4R is 'said to be a 'better' bike than a S4 but when speaking to 'others' they say don't touch an S4 with a bargepole lotsaproblems. Now I really wanted an air-cooled 4 valve bike but these do seem to be a fair number of S4's about at sensible prices. Genuine feedback on any regular or inherent problems on the S4 would be appreciated. thanks David
