people do the same with the 600rr's and it looks a heck of a lot sexier!!!! i havent heard of anyone doing heat damage to the undertail sections though.
i have that one too, it is a good read. i need to reread the suspension chapter so i can understand it a little better.... last time i read it i just read it i didnt try to understand it. huge difference.
i used to watch the trials guys all the time on speed, but thats was way back when when speed actually carried racing!!!! but they are pretty wicked awesome i have always wanted to ride one of those things.
