Steering head bearing alternative to stock?

I can't seem to get a straight answer anywhere about a suitable replacement (tapered) for my stock head bearings. Wondering if anyone has had any luck and could offer up a part number that would be suitable for a 2001 M900. I tried speedymoto but it doesn't look like they have them available just yet.

Cheers!

Why not try looking for 851/888 bearings? They share the frame with your Monster or visit, http://www.ca-cycleworks.com/shop/catalog/ducati/chassis.html and look for chassis and scroll almost all the way down, you'll find your bearings for $104.00 or http://www.speedymoto.com/Merchant2/merchant.mvc?Screen=CTGY&Category_Code=BR

Yes, both are, SpeedyMoto...

A 94 M900 uses SKF 639172 Outer and SKF 639174 Bearing

I bought a set recently which came as a 639174 assembly

Katana on the UKMOC website dug up the following info

Timken
L44613 Outer race
L44645 Inner race

***
509592A Outer
509590A Inner

Many companies such as WEMOTO in UK or Desmo Times in USA do tapered roller sets which improve handling and last much longer .

Pre-2002 should use the same old 26x52x15 bearing that Ducati's been using forever.

I just ordered one (yes I only needed one, its a long story, but you change them in pairs) for $34 shipped to the US from simplybearings.co.uk.
I've used them before for other bearings & they have quite a stock & are pleasant to work with. They take Paypal too & don't have issues shipping internationally.

BevelHeaven also appears to have them, for around $35 before shipping.

Thats interesting - can you point me somewhere regarding details?
The only thing I've read about seals dragging was when someone used bearings that were too tall.
The ones I have coming are the same 15mm height as stock. I suppose I'll see soon enough..

I have had this problem as have many others.
The rubber on the seal interferes with the top of the roller cage and when tightened down causes a significant resistance to rotation. I fixed it by adding a shim (top and bottom). BTW I got my bearings and seals from speedymoto

There has been a recent discussion about this on the 'other board'

That site is run in a dictatorial fashion by an elitist few, of late the technical content is somewhat lacking
I've never had a problem over their. The link that I tried to post had a great deal of info that the original poster may have found useful.

I've also posted links on the DMF pointing over here and never had one of the "Dictators" dissabled my link. Those damn elitists!!!!!!

pm me the link, there're quite few regarding the issue.

I actually find all 3 forums to be quite informative ... The speed of answers varies from one to another, but, you get answers ...
