Just got back from a ride with the wife and noticed that my Battlax BT023 rear (on my 07-ST1300) was vibrating a bit in slow turns... yup... cupping badly after 4500 miles. I am so tired of buying tires... I am preparing to go to the darkside... but have a couple of quick questions. 1) My speedo is almost exactly 10% fast (60mph indicated is really ~54mph gps)... will the Hancock 110 help with this? as in, is the Hancock a bit taller (I am hoping so...) and 2) Have any of you running the Hancock experienced issues trying to get the tire balanced? (Did a simple spindle balance work, or do you need to find a shop that will do a professional balance job?) Thanks in advance... James
