Those bikes are a handfull, check them out in slo-mo and pay attention to the front wheel, almost never straight until touchdown.
When Jay Turner gets his figured out , LOOK OUT!
Tak/DJ when they quit breaking parts same thing.
There is another blown bike that runs well but has limited resources to run the full circuit, look for Jason Pridmore at Norwalk and Indy.
He qualified 3rd last year at Indy and then the rumors started flying if "they" were going to ban the supercharged bikes.
There is at least one being built that has not been out yet, it is a two year deal building one of these monsters.
All of these bikes are capable of low 6 second runs.
Ted K. you are correct with the cylinder pressures these guys run, it IS a bomb waiting to happen, if a valve hangs a little look for a flash.
They have ballistic belts around the heads to try to hold the parts in, if such an occurrence does happen.
Enjoy !!
