Ok I grew up in the dirt....and if anything i did my body MORE damage BECAUSE of that dirt "training" I layed my Goldwing down doing 65 around an off ramp (no that was NOT excessive speed for THAT ramp) I had ridden that ramp for the last 11 years never any issues...I had ridden bikes for over 20 at the time...this day some truck had DUMPED oil the entire length of the ramp...so down she went but BEFORE the final "fishtail" I tried to RIGHT the bike by PLANTING my foot (just like on the dirt) but it's a Gold wing doing 65 not some KZ doing 20...your sitiation is similar in that it's a fluke thing and has little to do with your bikes ability (or your's) to "stick" in a corner...keep riding is the only advise I can give you...take it easy and keep riding...your confidence in your ability and your machines will grow and you WILL get beyond this...just keep Riding....I left the road for 6 years and MAN the ghosts get bigger and spookier...keep riding....
