Hello all, I am looking at getting a leftover '09 yz450f. But to my total surprise, in my search for good deals on dealer leftovers, I have found a new (unsold leftover) 2006 yz450f for a great deal. I have no idea how a bike could go unsold for that long, but apparently it happened. The '06 is $800 less than the '09. I have been reading and researching all I can find about these two bikes. It sounds like the '06 through '09 are very similar bikes, with relatively minor changes during these year models. The '09 is a little more corked up exhaust wise, but a Dr. D or other exhaust would be an easy fix for that, so I am assuming that would make them pretty similar in the engine performance? That would leave suspension and handling, is the '09 suspension much (or any) improved over the '06? They both use the KYB SSS systems, but I'm sure the valving and maybe spring rates changed some over they years, but would they be that different? To be truthful, details like a plush, compliant suspension, comfortable ergos, smooth easy clutch pull, etc. are more important to me than which bike would win in a drag race. So what do you guys think, is the '09 worth the extra $800, or maybe the '06 is actually a better bike and the cheaper price is just icing on the cake? And I am not really concerned with the depreciation/market value factor, I just want the funnest bike to ride. I ride/play motocross mostly, with some offroading and an occasional race to remind me how slow I am. Anyway, any help or advice, especially from anyone with experience on these bikes, would be greatly appreciated and help me decide which bike to get. FWIW, I am a 42 yr old C class rider, 5' 8", 'weighing 165 in street clothes. Thanks again in advance for any responses.
