Good one! The yellow one has had a TrailTech Vapor since I've owned it. I can't remember what the alleged mileage was, maybe 3-4K? And Old Blueberry has had a TrailTech Striker since the last two trips. Her original speedo broke in the crash. It had ~8K when we bought it, and we've put an average of 2K per trip X 13 trips = 26,000 (hard) miles, so total is somewhere around 35K? Newsflash: LDF has upgraded to 6 speeds and fuel injection. New Blueberry will be introduced in M14. Old Blueberry has gone to a good home. That bike has some history, starting with Rod Curie's TAT run with the band of gypsies.
