2014 YZ450

It runs further from the shock than the current set up. I race/ride motocross with my YZ. There is a WR for your application. I dont want a do all bike. I want a purely race bred motocross bike. Its BS when guys that have no intention of doing moto on the YZ complain about stiff suspension, engines that are too abrupt or too powerful, or oversteer. If you want a kickstand or a headlight and electric start and a low 1st gear get a WR. We are still riding around with an extra 5th gear, actually low 1st gear, because of this. I would much rather have the lighter, narrower, and more durable, 2nd, 3rd, 4th, 5th gear 4 speed tranny of the past. That 1st gear is absolutely useless. I dont even use it in the pits!

While your post is arrogant, I pretty much agree, I choose a YZf for offroad racing and not a WR because I want the same things out of it that you do. Recreational riders more than likely would fit a "stock" WR far better than any type of racer be it offroad or MX.

That may not be true of the 2012 WR450. Whole different deal.

Gray I am told you need a new CPU in order to really make the bike go though.

True. And cams. So? Has the suspension, the electricals, the wide ratio box, and it handles.

Everyone I have talked to loves it...until they lay it over and have to pick it back up.

Cant wait to see pics of this new 2014 yz450 !

Dubach trying out the new route around the cylinder...

Interesting. I don't really see this reducing heat on the shock much but it is a good way to move a little weight forward...

Plus now you can burn your leg on both sides!

The goal wouldn't be to move weight forward, but to continue to centralize mass by moving the muffler more toward the middle.

Second you can burn both legs on the '09-current Honda 450s as well.

Same thing, isn't it?

With all the effort people are going through to move the entire engine forward I think moving the weight forward is in fact a primary goal.

Maybe to certain people, but Yamaha's goal is to continue to centralize mass, wrapping that header pipe around the cylinder is doing basically zilch to put weight on the front end.

I would say moving the muffler from hanging out the rear side panel to being closer in will the the bike an even lighter feel, and continue to centralize mass. Unless I am missing your point.

It appears to really move the entire silencer forward. The silencer is completly covered by the side panel in the Transworld picture of it. (Sorry, I saved the pic to my computer but do not know how to post it on a reply)

If this mod becomes economically available I'll consider doing it simply because everyone raves about how good a mod moving the engine forward is, ie moving the cg forward.

I won't do the engine mod to my bike because it's too damn good the way it is and it's too big a change in my opinion. But removing the aft mounted "tornado", it's associated heat shield and shifting the weight of that and the head pipe forward (plus a more forward mounted muffler) will shift the cg forward just as moving the engine forward does and will help centralise mass as well.

A very elegant and subtle improvement to an already (arguably) perfect bike.

we moved both our bikes engines forward and we had to redo the suspension,it totally changes the bike but it makes it turn very well and holds in the rut.makes it a better bike coming out of turns when on the gas.if your a yamaha rider its the way to go unfortunatly a friend let my son ride his 13 honda and now we have three yamahas fore sale.

There are new photos of the JGR team testing that new wrap around exhaust routing with a custom FMF system. The silencer is moved forward significantly almost completely hidden behind the side plate. That should have a significant affect on centralizing and moving the CG forward.

Hopefully the air fork proves itself on the Crf and kxf so yamaha will see fit to put it on the YZ.

I don't think 2 lbs justifies having to check my forks every single time I want to throw a leg over my bike unless you are some professional trying to earn a living off it. I doubt 2 lbs would even be noticeable even for pros in most cases. Never mind having to put doubt into the seals blowing out over huge jumps.

How do you figure it moves it forward significantly? Only way it would be significant in my eyes is if the muffler were moved forward past the centerline. Not trying to be a jerk, it's just that your statement makes no sense to me unless the muffler is mounted to the fork. The goal with Yamaha is to centralize mass to give the bike a lighter feel. You move your body forward 1/4" it will like have an exponential affect than a 1/2# header will.

"Significant" is a subjective word. I don't know about you, but in my mind, moving the muffler (probably 70% of the exhaust system weight) forward 4-5" is significant. In spite of the fact that the muffler hasn't been moved forward of the CG, it has unquestionably moved forward, as well as downward.
