i think dirtwheels is bias against yamaha but i think tri rap is wrong, the suspension is not terrible, i think it is better then the raptor. and It is no where near the power or comfort of my raptor no it is not near the power of a raptor , i think it is way more comfortable, i love the big seat. now my z can keep up with a stock raptor, because ive modified it a little bit. but i have owned both and this is my 2 cents, i think you should think about stuff before you say it.
