Quick Question about the Steering Head Bearing.
If I am correct in doing my research, I have found that pre-02 Monsters ("hooped Monsters", or 851/888/Monsters) and Supersports come from the factory with tapered bearings - this was because the superbike series at the time of origination (851/888) came with tapered bearings, and the Supersports and Monsters used the same steering head tube diameter.
Newer Monsters and the like came with standard bearings and also feature a larger steering head tube.
Are the SpeedyMoto tapered bearings an improvement over the factory bearings provided on the older Monster's and the like? (I'm asking about the Kit-2, tapered bearings for pre-02 Monsters, all Supersports, etc).
Does anybody have a source with them in stock? I'm seeing them out of stock lots of places, and didn't get a reply back from Speedymoto themselves. Similarly, one email to a vendor (not a board sponsor) who listed them in stock must have been confused, because he told me they didn't make such a product.
Would I be better served going with OEM replacements?
I've been keeping up with the other posts/threads about freezing and heating to get things to fit, etc. I'm looking to put new bearings in when I upgrade upper and lower triple clamps.
WHen I put new bearings in my SS, the only ones available were OEM. I think the tapered bearings most vendors supply are to replace the non-tapered ones in later Monsters.
Right, that's the Kit-1 that Speedymoto sells. I saw the "Kit-2" as well, for the older Monsters and Supersports and wondered if anybody had gotten their mittens on these.

Not me, and I looked around for a while before I got the OEM ones.
I was going to source a set from Commonwealth Motorsports, but the listing "069191010" is a "Product Not Found" error. Running a google search, I can verify that the product number should be the aforementioned 0691.91.010:
SKF 26/52/15 bearings:

When I needed a set for my 96 I ended up getting them from Chris @ ca-cycleworks.
They were OEM bearings.
The OEM appear to be the SKF manufacture, yes?
I've read elsewhere that Timken bearings are the top available. Anybody have FHE? Opinions on the matter (re: bearing manufacturers)
I've gotten word back from SpeedyMoto, they have them in stock they say.
the OEM bearings are/were indeed SKF,
IIRC it was a problem with the cup OD in the aftermarket regarding availability.
If you bought 2 sets of bearings things would work, but the price became higher than OEM.
Any reason to try to upgrade from SKF to another, or SKF plenty good?

Yeah, I have inner 26mm, outer 52mm, and that's an odd sizing combo.
SKF is a good bearing and a common supplier of bearings on European products.
+1 on SKF.
Timken is good as well, I wouldn't mind using them if they've got the same size.
