trialsrfun Posted August 21, 2017 Report Share Posted August 21, 2017 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?

chappo Posted August 22, 2017 Report Share Posted August 22, 2017 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. 1 Quote Link to comment Share on other sites More sharing options...

sherpa325 Posted August 23, 2017 Report Share Posted August 23, 2017 (edited) 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.

bullylover Posted August 23, 2017 Report Share Posted August 23, 2017 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. 2 Quote Link to comment Share on other sites More sharing options...
