TRI-Z What makes you think that it is a yz frame , It is A yfz660r raptor, the frame is nothing to do with a motorcycle. It is a very well designed and most resembles a aftermarket 250r frame.And just what is your point any way The YZ motorcycles are designed for motocross out of the box, nothing wrong with those frames.

 

Drag races don't meen a holelot when it comes down to it. yes they are fun but in the real world of racing the raptor is proble going to kill just about every thing out there.even if it dosent its a heelof a bike to start with. if i can do to the raptor what i did with my warrior some other racers are realy going to hate me. heck they hated gettint their buts wipped by my warrior. but the bottom line is ride what your like and remember the bikes only as good as the rider.
