Well, I saw the '06 450 in Lagun Seca. man, it sure looked good. From sitting on the bike, it does not feel much different than my '04 as far as ergos. To me, that is a good thing. The bars and pegs felt good and the tank seems a little slimmer. The clutch pull was like butter. Very smooth and light. Looking at the motor, it looks similar to previous years, until you really look close. Ofcourse, the front of the motor has the built in oil tank. The cylinder and head are much more upright. They are not tilted forward and are almost straight up and down. The new 5sp gearbox has the same ratios in 1st - 3rd as the 4 speed. The yamaha rep told me that the bike weighs the same as the '05 model. Although many things were done to reduce weight, weight was added in places as well. He said the new forks are heavier because of the increased complexity of their design, the rear shock is beafier and heavier than before, ofcourse the 5 speed weighs more than the 4 speed did. The objective with this bike, he said, is where it carries its weight. He also said that the motor is much more smooth and has been melowed even more to be more rideable. It had a 739 on the fron and a 756 on the rear. It also had a small rubber buffer pad under the chain slider. Wear here has been a problem on the yamaha for years. All of the plastic has a different look and different lines than previous years. The bike looked good....I can't wait until december BTW.....I also saw the Kawi 450. The frame is very VERY similar in looks to the Honda. It just didn't look as good to me (fit and finish wise) as the Honda or Yamaha. Not very impressed. Ofcourse, performance may be a whole other issue....i just saw them sitting on the stand. I also saw the Aprilla 450 twin cylinder 70hp. It is a awesome looking machine. Aprilla had one on display in motard trim. very cool I also saw the original yamaha 4 stroke. it was Doug Henry's works bike.......also very cool to see. Got my picture with that one.
