06 YZ 5 speed Oh Baby!

I am so glad the 06 YZ is getting a 5 speed tranny!! It's also getting the aluminum frame. I think this bike will be a great MX ride but it may be a great off road racer as well.

Look out Honda!!

I like the 4-speed myself since I ride mostly mx tracks and open areas but some woods too. I wonder if the aluminum frame will be more prone to damage than the steel frames. But the yellow bikes will be kick ass to see on the tracks no doubt! :D

Here in Cal with our open dez stuff a 4 speed isn't the best set up. Not to say we don't get into some really slow gnarly stuff. We just have less mud and trees in the dez. On the track side of things I still think it will be better.

I think the new 5 speed alone will sell more bikes. I think the new YZ will set the standard.

5spd, alu frame and the anniversary yellow look is nice! Looks to be a great ride.

I couldn't wait to get a new '06 450. Now I'm not so sure and I'm eyeballing the RM.

When it came to be that Yamaha was not able to save one LB over the '05 I was like, 'what?'. :D Most people thought that must be a misprint on Yammie's website. Nope, same weight as last year. That's the same weight even with the addition of the Ti shock spring. So the new bike, motor and frame, is actually almost three pounds heavier than last years model and to save face Yamaha went with the expensive shock spring.

I didn't mind the steel frame and by now I've ridden all the '05 bikes and like the RM best. Until I see some tests showing me that all these heavy changes to the YZ make the bike better than the competition I'm not going to order one. I am keeping my blue 125 though.


I'm w/you on the weight. I was a lifetime YZ guy until I rode a CRF a couple years ago. I was really amp'd to get the new YZF, but the weight issue coupled with late availability and the numerous problems at the national level have me second guessing myself.

I've ridden the '05 RMZ and '06 CRF, both are excellent!

I can't believe Yamaha didn't have these bikes available by August/September. I really hope they didn't miss the boat!

I'm still not sure the weight thing isn't wrong. The 250F has the same engine, but an aluminum frame, Ti spring, lighter handlebars together should add up to some kind of weight loss. Unless the al. frame is just a big honking pig of a frame.

On the weight issue I didnt think Yamaha updated the "SPECS" part yet for the 06 models.It doesnt make sense really.Usually a Ti shockspring saves around 3 pounds and the aluminum frame should also save a few pounds.There is no reason for yamaha to make a heiver bike.My guess is that its still a misprint.


Maybe Yamaha decided to post the ACTUAL weight of the bike with some fluids in it.That is another option.

Reguardless of how much it weights it will be carried lower in the frame for a better center of gravity.

The new frame is solid aluminum forged and casted not hollow. The old frame was hollow tube chrome molly "steel". The new frame will be heavier than the old one, I do not know this for sure but I would put money on it.

IMO, they should of shaved more weight by removing first gear and giving us a three speed for MX. If one wanted more gears for trails and etc., what's wrong with WR.

Yamaha has the engine department down as far as reliability, that's for sure, but with this being the first year of their aluminum frame they might have some bugs to work out of it in 07'. I can't wait to see how it plays out though. But I am also amazed the there aren't larger weight savings with all they've done to it. Almost dissapointing, but if the bike rips screw the weight issue :D

Honda has the throne right now as far as the shootouts go, but with both Yamaha makeover and the Kawasaki 450 coming into play this it going to be an interesting year. Overall, any bike you buy these days are excellent and you can't go wrong with any brand.

We have some experiance with the aliminum frame on the 05 yz 250. I know its not the same as having the 450 engine in it but it did great for the 2 stroke and I am sure it will be great for the 450. There is a thread somewhere where they said that yamaha stated that the 06 frame is one pound lighter than the steel 05 and the additional 5th gear and other misc. small weight gains keeps the bike aroung the same weight. But as always that is just people talking. But I realy agree with Jeff wsu's last comment, pick your favorite color and you will be just fine!! Ride ON!!! :D

The new frame is not solid. It is just like the 05 two strokes excepts the spars have the cutouts on the inside instead of the outside.

Ok guys...

In the reviews and the spec adds, they had clearly defined the weight increase and decrease.

1- The frame is the same as the 250, but the "CAN" look has been inverted to the inside.

2- While the Ti rear shock has deceased the amount of weight, it is made up in other places, see below...

3- The Alum frame has also saved weight, But.... See below

4- Yam/Kayaba has completely redesigned their from suspension/shocks, thus created a heavier shock overall= Increased Weight

5- Yam has also switched back over to the 5 speed tranny, which in turn amounts to increased weight...

Yamaha claims that the overall improvement that it has made, has balanced the bike out to weigh the same as the 04/05.

To sum it up, at the cost of a lighter spring, and alum frame, you get new design heavier shocks and 5 speeds...

      2005 YZ450F, Athena Big Bore, Power Bomb, Q4.
      Ok.  Last fall after a decently hot day at the track, I noticed coolant leaking from the weep hole on my water pump after pulling into the pits.  Ordered an Athena re-seal kit, put it all back together and didn't really get a chance to ride it.  3 weeks ago, went out to the track, and after about 20 laps, it started leaking again.  Kept filling it with water to get thru the day, never ran anywhere close to dry or empty, jut a cup or 2 low.  Ordered a Hot Rods re-seal kit with bearing and also ordered a new w/p shaft.  Did it all again and got it back together, ran it, and as soon as it got to temp, it was leaking out of the weep hole again.
      So, what the heck am I missing?  I'm totally stumped on this one.  Is something wrong with my case cover?  Do I need to replace the w/p itself?  I'm feeling like I should've just ponied up for the Boysen in the first place, and now it's biting me in the butt.  Any help or suggestions is greatly appreciated.  Thanks!

      Alright guys, my 04 YZ450f runs fine minus some slight backfires when decelerating (need to adjust fuel screw). The other day when I was done checking my valve clearances I changed the oil and filter and put the bike back on the stand, kicked it a few times without the ignition coil in to get some oil flowing got off and noticed a little drip spot on the ground, it was no bigger than a dime so I thought nothing of it. Started the bike with no issues took it for a quick 10-15 min ride, came back to the garage to find out my whole case was soaked with oil and it started pooling in the low spots on the clutch basket side. I cleaned all the oil off and took it out again for 5 mins to try and see where it was coming from, here are my three possible places but nothing directly leads me to believe it’s any of the three either.
      1. Decompression plug area
      2.  Valve cover gasket leak (not really sure because the amount of oil leaking Looks to be a large amount
      3. Oil tank (bad weld or cracked weld somewhere
      what are you guys thinking?

      Hey guys. I could really use your help diagnosing an issue that came up riding today. Bike is a 2013 YZ450F. Well maintained and haven't had any issues until now. Both the oil and coolant are new and levels are to spec. 
      After riding for about an hour in the sand dunes, I noticed a grinding going on on the right side of the bottom end (from what I could tell). When I looked to see what was going on my kickstarter was vibrating and grinding really loud. This was a different sound than if you engaged the kickstarter while running. It sounded less "clanky" and more "vibrating/grinding" if that makes sense. Grabbing the kickstarter and moving it didn't help the issue.
      When I noticed it, I shut the bike off and gave it a second. Being a few miles deep into the dunes, I had to get it out of there so I started it back up and it seemed fine- no grinding. I headed back to the car and after a few minutes, it came back so I shut it off again, started it back up and nothing. That process happened one or two more times before I made it back to the truck. Seemed to run fine otherwise. 
      Once I got it back to the truck I started it up and tried to pay more attention to what was going on but it wasn't doing it. I did seem to have more of a metal on metal noise coming from the motor. I started and stopped the bike a few times and after the motor stopped there was a distinct metal clank/grinding noise that happened right after the motor shut of for maybe half a second. This doesn't happen every time. 
      I tried doing some research and have seen things that make me think it could be the spring that connects to the kickstarter, or the kickstarter stopper plate- but really I have no idea.
      Seems strange that the issue is off and on.
      Thanks for the help!

      Does anyone know if there is any differences between the 2 radiators? Will the yz450fx radiator bolt on a yz450f? What I am wanting to do is wire up a fan to my 2016 yz450f. I know how I am going to do it I just don’t want to use a “universal” fan kit. What I would like to do is get a 450fx radiator and the direct bolt on Trail Tech fan for that radiator to have a good clean look.
