Had a look at that website, what's the difference between a DID x-ring premium gold chain for £104 and the DID Heavy duty x-ring black for £80?
Also it lists spring links for each separately for £5ish is this something that is needed aswell or not (sorry probably a silly question but I've not dealt with a chain since I was 17 and my mate got and fitted it for me then.)
Another question I meant to ask, what sort of mileage do you get to a tank full? I'm on 180 miles now and still not on reserve, can't remember if I put some in from a can since the last proper fill up though.
