Dont get rid of the bike. Those things are awesome and you can do amazing things with them stock. I love the CRF! I want one so bad, I could hit the jumps at the local tracks on a stock bike try doing that on a quad. And if you race there are so many of the bike you cant be the worst one. But a trx 450 is a good quad. There is a couple of franken quads around here but most of them are like Yamaha blasters with 85cc or 125cc honda cr motors on them. they are cool. If you get a crazy mod quad let us know how it runs
