Taper roller head bearings

Featured Replies

When looking through posts here in the Bultaco section for information on availability of a bearing kit to fit taper roller head bearings to the Bultaco Sherpa 199a I saw Pyramid parts mentioned as a supplier but when I contacted Pyramid they had no knowledge of the correct bearings or the part number. Presumably the taper roller conversion is a satisfactory improvement.

Does anyone have any info on the bearings or a part number for Pyramid please?

I put some in my 199b a couple of months ago, they were from the InMotion boys, ( superb postal service ).

Fiting is easy, but do check and re torque after the first event they may need nipping up as they settle in.

They give a lot smoother action, as you would expect.

I have never had any dramas with the original ball bearing style and unfortunately the same can't be said for the tapered type in most gasgas bikes I've had in the last few years which seem to require more maintenance than the ball bearing style. I also recall reading somewhere that the Moto GP bikes all use the ball bearing style because they give better feeling.

Cheers Greg

pyramid ones don't fit.

 Do the Inmotion ones fit correctly, better to stay with the original loose ball bearing type otherwise.

The In Motion ones fit very well. I have them in all of my three Sherpa`s and it has made the steering in all three feel much nicer. Graham.

Just purchased a set from inmotion (great service!) for my model ten. They fit perfectly.

Interesting that the steering head bearings never changed throughout the time the bikes were produced.
