Parts from 03 yz250f: air filters, GYTR folding brake and clutch levers, all cables, spare plastic.
Will any of this fit my new 06 450ltd. on the way?
Thanks

I dont think any of the plastic will fit. Even if the front fender will fit, it looks different. I put my ASV levers, stainless oil filter, magnetic drian plug, 18" rear wheel, 12 tooth counter sprocket all on. Saved me some big bucks. :thumbsup:

Aford541,
Did you stick with the '05 gearing, the 14 drive and 51 rear sprocket? If so, did you notice any difference between stock '06 gearing and the sprockets you transferred to the '06? I have sidewinder stuff that's brand new on my '05 I want to transfer. But I rode the stock set up and liked it. I just want to know how the gearing will affet the bike. Thanks, Matt

I actually ran 13-49 on the 05, if I did anything I think I would go to a 14-51 or 14 -50 to make the gears last a little longer you have to shift this bike so fast its scary.

The stock '03/'04 had a lower primary ratio than the '05/'06 does (2.818 vs. 2.652), and came with a 14/48 combo on the rear. This gave it a 1st gear of 18.64 and a 4th of 10.10. The '06 comes with a 13/49, if I'm not mistaken, and that would give it a lower 1st gear of 19.28. 4th is 10.90 and 5th is only 9.52. These are overall ratios, keep in mind.

The point is that the bike is geared very low as delivered, IMO, apparently to try to fit all 5 gears into an MX speed range. But doing so causes the effect of the gears being spaced perhaps too closely together to be practical that you noticed. And as someone who runs an '03 with a 15/49 (for a low gear of 17.76), I can tell you that the YZ450 does NOT need a lower 1st gear.

The first thing I would do with the bike is put a 14 on the front and go from there. That would give you a set of ratios a lot like the '04 4 speed was (low would be a little taller, but 4th about the same) and you'd shift more like the 4 speed; a lot less. The one I rode was set up with a 14/50, and it was great, from a gear box standpoint. It let that big, wide power curve work for me.
