Warriors are great quads. The are the #1 selling "sport quad" ever. Since the introduction of all the new 4 srokes, it is the very bottom of the food chain. It is still a good beginner quad. Depending on what you want it for you can out grow it quickly or it could be great for you. If you ride a Z400 or a one of the 450s you relize very qiuckly that a Warrior is a toy compared to them.
I came off a warrior and am now riding a z, No comparison between the two
