2007 YZ450 - Steering Bearigns


Recommended Posts

Needing to replace the Bearings as bike's handle bars stick after a while of in-activity. Looking on-line, under OEM Steering it only shows 1 set of bearings needed but it's my understanding that if this is to be done right, 2 sets are needed (Top & Bottom). Would I be correct i my understanding that the diagram under the "Steering" section is for the Top Bearing and if so, where can I find the Bottom Bearing ? In anticipation ... Thanks for your help. 👍

If you don't go OEM you can get both bearings, the bearing race's, and seals from All Balls for just a little more then the price of just 1 OEM bearing. Generally I pefer OEM for most parts but since the stearing bearings usually wear out from getting dirty, I'll bet the ALLBalls will last just as long or maybe I should say will probably wear out just as quick. Stearing head bearings need to be cleaned and greased at least every year.

If you ocassionally use a pressure washer, try to stay away from the steering neck. IMO I think pressure washing accelerates the stem bearings rusting. My buddies '06 bearings actually rusted so bad, they siezed up tight over winter storage !

My 08 wr450 came with the older bearings. I just had to replace the bottom bearing. The top bearing was perfect, although the dust seal was torn from the factory. My sons 08 yz250f had a torn dust seal too. I think they could come up with a better design for it.

While this is completely true, my 426 has survived countless pressure washings, my '09..............not so much.

I always avoid the stem area as much as possible, but on my '09 it still got in there. 👍
