Yeah, you're right there but most guys aren't running stock engines on any pro level. I know what you're saying though. The guys I mentioned are also awesome drivers, some of the best in the world but they chose the z for their quad. Although I did see Corey Ellis's race quad on sale on ebay awhile back. Peace and God bless.

 

The LTZ tranny is not the exact same as the DRZ tranny either. They had to beef up the gears to handle the extra stress the ATV puts on them.
