I wouldnt wory abt beating the kx. It is a crappy quad. A quad for people that dont no how to ride. So if ur friend does beat u just say(well it isnt that hard to lean back and hit the gas.

 

I'd say get DS650 i take banshees everytime on mine if both bikes r stock. If you don't plan on doing that much to your bike get the DS but if u plan on sinking alot of money into a bike and make it the craziest thing around get the banshee. ppl say don't get DS if your small i am 5'10 and 145 pounds but i drive the ds like its a 2-stroke and have no trouble doing so. Should test run each of them just to make sure u don't regret your choice.
