Fyi for apex RTX, rear suspension shock linkage bearings, they are fixable....

Hope this info helps others with a pro-active CK rear suspension. The '07-'09 RTX has a billet aluminum shock linkage bracket with 2 non greasable needle bearings. Yamaha only sells it as a complete assembly for big $$$. I pressed the failed larger bearing out. The smaller bearing looks very good yet. The original larger needle bearing is an IKO BRAND: TA1825Z. The seals are: DS18253 which is 18 id. x 25 OD. x 3mm wide. NTN also makes a identical bearing: HMK1825. Bearing dimensions are 18 ID x 25 OD x 25 mm WIDTH. Good luck finding these as they are not stocked well in the USA.
Motion Industries was the only place able to get both the bearing and seals quickly. I had to buy two sets due to minimum order requirement, so I may be willing to part with the other one if someone is interested. The larger bearing and seals should be approx $30 shipped vs. approx. $160 or more from Yamahafor the entire assembly. Why they didn't offer bearings separately is beyond me... They will probably never fail if it is removed and greased in the off season, but I just noticed mine was rough after the rear pivot arm tubes broke on each side of the rear pivot bracket which I didn't even notice for some time....
