I have never owned a 426 or any 4 stroke dirt bike for that matter. I found a 2001 yz426f on craigslist for 1400 bucks. Original owner and looks like a very clean bike. I am going to check it out tomorrow and was wondering if there was any problem areas with these bikes i should watch out for. Is 1400 a reasonable deal? I am going to doing some more open trail type riding and maybe hit the dunes once or twice. Are the yzs decent bikes for trial riding? I am also curious on how high maintance these bikes are. Any info and expirence is apreciated, thanks.
