The guy had roughly 4000 miles on his 09 which would say the tires were in good to very good shape also, he is the kind of guy who is more than anal about the maintenance and upkeep so I am pretty sure all the pressures were good. According to those who witnessed the crash from the rear, say there was no wind to speak of. The common statement from all who were following seems to be that he was hitting close to 110 when the bike just started to develop a noticeable wobble which continued to get worse until it disappeared into a big cloud of dust with parts going everywhere....
