Stiff steering

Your ball bearings are shot more than likely the same as mines were, replace them with tapered roller bearing kit from wemoto.

Will last you years and years!

The stock bearings are really bad and don't last.

Slob... does the tapered bearing just sit there or does it get pressed into the frame??

Also do you know the bearing size??

Interested in doing this on my dtr.

Thanks

The bearing outer race can be tapped in with a suitable drift,

This is the kit I used, very well priced cause I checked the codes on simply bearings. This kit comes with two bearings for top and bottom If you want to do it properly

And if you just want to do the top one just get this on.

If you do the the bottom one DIY you will need a dremmel to cut the old inner race off the stem and you will need a vice and some wood to tap the new one on with the yoke inverted so you hit it on to the collar if you get me, also I had a hard job getting the lower outer race out the frame because of corrosion.

The bottom bearing is certainly imo one of the hardest jobs to do DIY on the bike without proper tools, but it definatly can be done.

The top one is a simple job though.

It'll just sit there but you'll need to put a race in there for it to sit in i expect.

Cheers again guys, if i just went with the top one would the steering be ok, or will i encounter issues down the line where i did not replace both?

Doing the top one should be fine. Reckon it would solve the problem.
