I pick up my 06 YZ450F this Friday. Have not ridden much at all since I sold my 04 250F two months ago, and have admittedly been out of the TT loop lately. Wondering if anyone would be kind enough to give me the short list of issues or concerns that might have cropped up in the forum? Only thing I have experienced around here is one early clutch failure on a 06 250F, but nothing else. Is my new toy really that good?
