I changed mine when I first built the bike. It already had tapered bearings (I had to cut the bottom race off) but they may not have been the originals?
I'm fairly certain I didn't fit the (supplied) lower seal for the reasons mentioned and that there wasn't one in there already, there is a large ally washer sits under the lower bearing though. Can't remember the brand or supplier but AFAIK they are all the same at least for the '99 models?

Aha ... we have the glimmer of a link then.
I'm guessing that your top yoke nut is the type with holes in for a peg spanner ? Mine's a normal hex. Maybe that's an identifying feature between the two ? Don't suppose you have any old bearings hanging around, to measure up ? |

To be honest I was expecting some after nineteen years and after a few people saying they had to cut the lower race off the stem etc. but no such issues- I carefully tapped around them with a stainless steel 'scraper/knife' my Dad made years ago to put in my tool box knowing it'd come in handy. Tools for the job: Perfect fit:

After a little more research tonight I found this which may be of interest to those about to embark on steering bearing replacement.

Nice one, Flip.
Bigger bearings in the later frames then. I'm glad I asked now. Otherwise I probably would have bought the wrong ones. Interesting that you had no trouble with the seals. Since yours is the same frame as mine, that bodes well. I think that Capo's frame would be the later type, so maybe the issue with the seals causing stiffness is particular to that frame. Dukedesmo left his seals out and his is an early frame, but I'm not sure whether that was in anticipation of water retention or because of the above. |

Coming back to this thread in my search for new headstock bearings.
I have used Pyramid Parts for fork seals and bearings on past projects. They supply mostly NTN or Koyo bearings, so quality makes. And if you know your sizes and search under that rather than by make and model you often find the pricing more advantageous. Just try searching BR49 on the Pyramid site and you get widely varying pricing for the same part depending on the model of bike its noted against. So for my M900 95 I need their BR49 kit (26×52×15) at about £29 delivered, which seems a very competitive price......which my suspicious nature makes me question whether I've got it right!!!!! Anyone?

I fitted Pyramid BR49 to my M900Sie last Winter from PKN they were only 23 quid then, but I see they have gone up!
https://www.ebay.co.uk/itm/292170718594 I probably won't use those again, but I'm not un-recommending them as such. I found, as others in this thread have found, that the seals seemed to be too tight, I didn't fit them as I was worried about the drag. I used plenty of Moly grease instead. The little sachet of grease that comes with them is way inadequate. Of more concern was that the lower stem inner race was not an interference fit on the stem, While there was no play as such, it could be revolved and removed easily by hand. A bit of locktite nipped it on instantly, but that's not the way it should be. In use they are excellent and have transformed the handling and feel of the bike, so no regrets. I'll probably change them again long before their service life expires, you can't beat nice fresh bearings and tyres..

Sorry, I don't recall the make. There's nothing on the box or seals either.
Interested to hear how yours fit the stem.
