Well, let me start by saying that i owned three previous Yam thumpers, all bought new, including the first 98 YZ400f that started it all. For the last 4 years however, I've been on Hondas. While I was pretty happy with the bikes, Yamaha was the only company paying contingency in the 50+ class this year, so I'm back on blue. From reading alot of the mag reviews, some are saying that the new silencer chokes the motor a bit and its down on power. Others have alluded to the super smooth and easy to ride, non tiring power. As someone who competed in over 110 motos last year, that IS a very important thing to me. All the power in the world isn't any good if the bike isn't putting it to the ground. As such, I'm gonna start the season with it bone stock. I was pleasantly surprised to find that after tearing the whole new bike down this weekend, the steering head, linkages, swingarm and wheels were all well packed with grease from the factory. Hondas come with a light film, if that. I also notice that many of the fasteners are larger or have deeper shoulders to prevent sockets from stripping on them, i.e., the side panel, seat and radiator bolts. The quick adjust clutch, ProTapers, Excell rims, filter access (that was dry from the factory btw), are also nicer than the Honda. The side panels lock into the airbox much better than the Hondas, which often popped out in small crashes. The suspension sounds like its universally well received from anyone who rides it. Maybe this 200 pounder won't need new springs afterall. Im really looking forward to racing this new bike this year.
