All you have to do is look at Doug Gust he rides a z400 yes with lots of money into it but still whups the 450s and just wait until the z450 comes out

 

What the hell does that have to do with a stock z400 with a pipe. The 400 he rides is not even close to being stock.

 

Doug Gust hasn't done much whooping this year! LOL. I am sure the Z450 or whatever the hell they are going to be called will be a formidable ride. Maybe Digger can get back to winning when he races that bike, but this year the Z hasn't done as well as last year!

 

Yeah but if anyone else was riding his z they wouldnt be doin that good. When it comes down to full race quads its all the rider not the bike.

 

yes the z is not as fast(in the 450 class without serious mods to the head and due to web not updating there cam profiles for it) but it does not have a problem with turning pistons sideways iether. and with %12 nitomethane you can get about 68-72 horsepower out of it and the bottom end still stays together even when running a shorter rod so i guess every machine has its advantage besides how many times do you feel like tearing down your machine.

 

Hasn't Doug Gust been racing with a broken back and ankle or something?
