I have two sets of rear suspension links (dogbones) to suit a Suzuki V-strom or SV650 (and possibly other bikes I guess). I inherited one set from a friend who had them on his SV650, and the other set I purchased for my V-strom, but have never fitted. The set I just bought were specified as lowering the rear of the bike 25mm. I don't know about the other pair, but they're marginally longer, so I'd guess a bit over 30mm or more? They probably act differently on an SV650 though. Looking for $25 per set.
