i have an o7 classic bought january 08 new, i have put 23000 miles on this bike , when the original tire started to wear i was getting a shake in the handlel bars between 40 and 50 mph accellerating and when deeaccellrating, well i lived with it for a while then installed an avon front tire and from new i had the same shake in the handle bars, i allways thought it was the inbalance in the tire tire that was the cause of this, i had a few mechanics ride it and they said dont worry its not as bad as some bikes ,, so i now have installed a new avon tire with dyna beads , this is the third front tire on this bike , first time to use dyna beads , and now i am shake free bike rides smooth as silk , it works for me
