I've been pretty happy with my '10 YZ 450, particularly after I had my suspension revalved for my riding style. I read in MXA about the "wiggle when entering corners" that their test riders describe. I normally take these comments with a grain of salt, (gearing it down 1 tooth, etc) but I find this is exactly the sensation I have been trying to pin down for a while. They say it is cured by a 1.5 mm longer pull arm on the linkage. This allows the bike to set lower in the rear (by 10 mm) and allows different options with sag and fork height. Pro Circuit is their vendor of choice, but they have none available. Are there other reputable purveyors of suspension components that could supply this part..?

From another thread these parrts are from a 2007 WR450;

5XC-2217F-90-00 ROD, CONNECTING 1 $51.12

93315-32269-00 BEARING $9.08 2 $18.16

93109-22019-00 OIL SEAL $8.63 2 $17.26

90387-14009-00 COLLAR $7.87 1 $7.87


That is all the parts needed to make it work, depending on local prices should be around $100 total.

What is the difference in length between the 2010 rod, and the WR part..?

here is a print out that shows the connecting rod fits much more than the 2007 WR 450F, it fits several years of the YZ450/250 also.

What is the difference in lenght between the 2010/11 rod and the WR/etc part #5XC 2217f-90...I don't have a problem using a Yamaha interchangeable part, but I need to know what the difference is between the parts, is it longer, shorter, and how much..?

2010-2011 are identical. I have the RIDE ENGINEERING one on mine and I love how it made the bike handle. www.rideengineering.com

How did it improve the handling versus stock?

One more time: How is the WR part(or ride engineering part) different from the 2010/2011 part? Is the WR part longer, shorter, and if so, how much longer/shorter?:smirk:

It helps and keeps the thing from wanting to knife into the corner. It tracks better in accelerating Bump, doesnt have the harshness in the midstroke. It lowers the back end 10mm so obvioulsy it is longer then stock. Click on the link I provided above and read about it. I dont know about the WR.

I don't know the exact length but the WR part is slightly longer. I know the PC part is 1.5mm longer. Sorry, I didn't have the exact info, I just copied the part info from another thread when I saw it some time ago. I'll do a search to see if I can find it again.

I know the pc part lowers the rear end 10mm. Then people run 100mm of sag (instead of 105mm with the stock link to slacken the head angle) and raise the forks 5mm to lower the front end an equal amount. I think the WR part lowered the rear end 12mm.

I added 5mm spacers (preload to raise) to the front forks to accomplish mostly the same thing. I now run 100mm of rear sag. I couldn't drop the forks any further as I am running them flush with the triple clamps.

Here I found the other thread. Looks like the WR part lowers the rear end 11mm.

Then that doesn't answer the question, does it?

EZ, Read the original post:

http://www.thumperta...152#post9962152

The WR link is going to be longer, same as the PC link, for less than half the price. It lowers the rear, which makes the head angle more shallow, which slows the steering and makes the bike more stable at speed, but "lazier". You might like the effect, or you might find that if you adapt to it, you like the quicker handling of the stock geometry better.

Is there no risk that the rear wheel will hit the rear fender/subframe when using a longer link????? It lowers the bike 10-15 mm and generates a less progressive rising rate. So for it not to hit, the stock clearance must be in excess of 25 mm. Anyone know?

Thanks, Grey, I had read that post and couldn't find it when I needed it for reference. Have WR parts on the way. I'll check back in with a report of how it changes the handling in a couple weeks..

How will the longer linkage differ from the top out plate that shortens the shock lenght by 3 mm?
Enzo sells the plate for $40 and it's claimed to lower the rear by 10mm.
I need to go with one or the other. Anyone the enzo part?

The top out plate shortens the shock travel. Why would you do that?

adding 5mm preload will drastically change the forks........may make them harsher on the chop and it definetly speed up the rebound..........did you account for the changes?.........think i would rather lower the rear instead of adding that much preload to a fork

Why would it do either? Preload does not change the spring rate, and until you have too little sag to allow proper extension under unloading conditions, additional preload will not alter the damping characteristics or operation of the suspension unit. It simply positions the fork or shock higher or lower at a base loaded condition.

there is a reason tuners and manufacturers run a certain amt of preload..........5mm is alot of preload on top of what was already there........i have ridden during testing and preload effects the suspension very noticeably imo....but go ahead throw another 5mm in there and see how it feels.........

it will make the current spring rate feel stiffer

Add or subtract twice that from the rear shock (only because it's easier to do) and see what effect it has on damping or spring rate (none). Forks are no different. Obviously there are limits, but 5mm won't approach it.

That being said, I prefer not to add preload to forks in most cases because I like them a bit further down in the stroke for other reasons, so if I were to want a shallower head angle, and decide to do so by adjusting suspension, I'd rather make the adjustments to the rear than raise the front with preload.
