Things that I've observed at trackdays :-
At breifing fellow rider saying " I'm a really fast rider on the road" = Knobbler on track
Blinged up bike in the Novice group = All the gear no idea.
Old bike a few places in front of me about to exit pit lane " Where the Fxxk has he disapperd too?
Trackdays are all about having fun , and bikes unlike cars are goverened by the rider e.g. A good rider on a crap bike will allways beat a crap rider on a good bike. ( I think I fall into the latter )
Also even if it rains go out , you have paid for the use of the track and you can learn bike control -taking it steady
And most importantly of all don't bin it!
