hey all. I'm thinking about buying an SV1000 (2003 model). Went to look at it and it's a work of art... one thing I noticed however is that the chain seems to make consistant contact with the swing arm, on some sort of rail like mechanism. It's the top section of chain (IE being pulled towards transmission) and where the chain meets the swing arm there is an extended length with a shape like this:- _|Â¯|_ so that it appears that it somehow guides it.. I've never seen anything like this before, so was wondering if it is a standard feature or whether it is some sort of freaky mod. The most concerning thing is that even when I sat on the bike the chain was still in full contact with the guide, so I'd have to assume that chain wear would increase (is this assumption correct?). Cheers!
