Well, finally it happened. Was riding pretty hard yesterday at a very fast, loamy mx track in central PA. Coming into a left hand corner with a little bit of spongy mud there, bang, front end gone and I was on the ground. Thank goodness for the Unabikers because I think the 50 cent radiators would have been dead. I've heard of problems with this bike letting go without warning but I can't be sure if it was related to that or just that I came in too hot and lost it. I have lowered the suspension and switched the tires. Overall, the tractability, handling and power has been superb. Wonder if anyone else has been in this situation. I hear the 250F is the same way.
