We have a few customers who go to these events. They are not really spectator events but to run your bike flat out they are a bit of fun. Twos guys are in the 200 mph club with Kawasaki ZZR1400's at over 206MPH with only minimal mods like pipe and a bit of lowering.
My Mate Patrik, does the wheelie thing and has done 219.9 MPH and has to go back and break 220MPH as he has done over 225MPH in practice.

I prefer corners, but it is all competition and competitive urges and testosterone seem to be the driving force here in the same way they are in other forms of motorsport.
