I might get the IMA triple put on while the forks are serviced.
Might as well replace the bearings?

Besides SpeedyMoto, are there any other interesting suppliers?
I heard about one called AllBalls, GoAllBalls or something like that....

SpeedyMotos are Chinese, if that matters to you. That's what I have anyway. Seem OK. You're near Sweden so can't you get some good ones from the fine bearing makers there?

Sweden? Is it SKF you're referring to?
[bang] To me, that's like buying Canadian....

Found All Balls, AllBallsracing.com, they have a kit for my bike at $ 47.

only the 'tapered-upgrades' - the tapered replacements for bikes originally equipped with tapered bearings (the 888/851 style and SS style steering heads, including early monsters) are SKF in manufacture, the same as OEM.

Ok guys I'm not getting what the issue is with the Speedymotos for +02 Monsters regarding the grease seals provided in the upgrade kit, per Duck Stew's thread. I'm not understanding why the spacer is needed, etc. I have a kit right here and was planning on installing it, but not sure now. Clarification is needed. Lots of clarification.

the spacer just provides room between the seal and the bearing so it has mo' room fo' grease

Put the inner race/bearing into the outer race, and then put the seal up against the inner race.
I suspect it will have the seal jammed up against the outer race.

Yeah but that kind of undermines the point of having a seal in the first place, correct? With that gap like that? Won't the grease come out? Still confused.

So you're saying that if the seal actually seals against the outer race as shown in my photos and Stew's, that this is a bad situation? I'm definitely missing something here.

The seal is meant to contact (and seal against) the bore in the steering head.

The SpeedyMoto bearing and seal parts I had, it would jam the seal *hard* against the bearing outer race.
Creating a good bit of drag, and likely killing the seal in short order.
Additionally, the bore/hole in the metal part of the seal was way larger diameter than the steering stem, so it wouldn't necessarily be centered.

it may wear the seal if it touches. it is supposed to be a base plate for the grease, i reckon

booger

OK, the seal with mine touch the outer race as shown, but are not jammed against it by any means. Anyone have any contact with Speedymoto regarding the issue? Seems they would be aware of such a flaw in a product they were selling.

It's a matter of premature wear, if that.
My guess is that's why Stu made the spacer - to eliminate all doubts.
Maybe it's an issue - I don't know.

At this point it's between .....
SpeedyMoto triple, including bearings (uncertain ETA)
IMA triple with All Balls bearings
IMA triple with Stu's Bearings
