I have a 1000 Vstrom that unless you count my yard and a gravel road is a road bike. I am 6'5" bare footed, 34" inseam and I have a corbin seat that makes me set even taller. I have lowered the front untill the shocks nearly touch the factory bars and put a brace on the shocks that helped the high speed handeling a huge amount. I lowered the back 1 inch with lowering links and am thnking about lowereing it some more but was wondering how much can you lower it before the back tire can hit when the suspension is at full drupe??????
