i bought my bike last year, and four times (now) while driving in town, i stopped and walked around for 30 mins, then started my bike up again, and it would not hold a charge, it would start, then die, on long distances it is okay. i took it in (the first time) and the dealership said they could find nothing wrong with it. i let it set for about an hour and then it was fine, i do not belive that my bike could overheat while only being riden for an hour of in town fun ( not fast not hard) ...yes it was a little embarrasing to have a $17,000 bike just dying in front of others (and my friends) if anyone knows anything about this please contact me---edward
