Hi, I am looking to get a used sport quad. I have not had a sport quad in over 10 years, so I need some advice. I found a clean 2007 yfz 450 that I like I also found a few 2005 and 2006 honda 450r's, I am also considering the raptor 700. I want to go fast allot of trail ridding and don't care about reverse. Can some of you give me advice on what not to buy and what to buy. Thank's for your help.
