i'm 15, and i'm looking for a cheaper sport quad. i haven't owned anything in the past, but i ride my friends z400 and 400ex, so i can handle something that's got ***** to it. but here's the main question- what's the cheapest and most reliable 400 i can get?

 

You rode them. Might throw a Yamaha 350 Raptor into the mix also.

 

check out craigslist in your area. sport quads are the cheapest bikes out there, so you should be able to find a 400ex or z400 for a good price. welcome to the forums, and good luck!
