The day you knew for sure........
.......You were no Kenny Roberts.
Three instances come to mind.
1. 1983 near Alices Restraunt, Ca. Cranked hard over on my newish 1982 Yamaha Vision, going as fast as I dared with the speedo buried past 85, I got passed on the outside by a guy who must have been going 40 mph faster than me.
2. On the way to the USGP in 1989 my dad riding behind me remarked on how much clearence I had between my tricked out BMW R100's cylinder and the ground.
3. On my Ducati 900SS in 1995 in California on my favorite road I got passed by a Virago.
