Hmm, if that's a genuine Swiss bike then it'll have been restricted when it was built. And the restriction won't be easy to rectify as it involves changing the cmashaft, the intel rubbers and the carb needles and slow jets. Wonder if the seller knows?
The camshafts on the restricted Swiss bikes are also used on the VT750 Shadow cruisers, so really are "tame".
But as you say, a different colour scheme.
Edit: Had confirmation from the seller that the bike was first registered in Switzerland - so, a restricted bike.
