I have never used them but hears several good reports on them on a Kawasaki forum I frequent. The K75 does not have the seals from factory but looking at those I would say they will do the job.

I bought some All Balls swing arm bearings a few months back, because they were cheap, and that's what they were, cheap! I never fitted them, I threw them in the bin.

I have seen many people be perfectly happy with their tapered steering head bearings, I have used them myself and they seem just fine. But I also looked into using their triple-lipped fork oil seals and found many people are really not happy with them, so maybe just stick to their head bearings?

As an aside I have found tapered steering bearings to require retightening very often as they never seem to fully bed in, though the distance between tightening sessions gets longer and longer the further you go. I am not alone in this though some people swear this means I fit them incorrectly, your mileage may vary

We offer All Balls bearings as an alternative to the OEM steering head bearings. In the several years the workshop has been selling them we've not had a set come back. At about US$30 a set they're far less expensive than the $58 each of the OEMs. I'm gunna use 'em in my K100/K12 project. You only need the tin plate at the bottom triple clamp, which is

Maybe the All Balls steering head bearings are ok, but I'll never give them a go after the experience I had with the swing arm bearings.
The reason that I threw the All Balls swing arm bearings in the bin is because the surface area on the swing arm pivot with the original Fag bearings is about 17mm and the All Balls surface area is only 11mm. All Balls do supply a slightly wider seal as a spacer but is totally useless.
So when you fit the swing arm and tighten the adjuster pivot , the #ucken All Balls #hit bearings are just to small and allow the swing arm to pull up against the inner gearbox face. I wish there was an All Balls rep in the garage when I was trying to fit them, as I would have jammed them where the sun doesn't shine.

Balls shoved where the sun don't shine?  I'd like to see that! 

Smithy, I am surprised to see such a difference in the surface area.  I would suspect a slight anomaly in the part number.  For what it is worth, I just grab the generic brand at the local bearing supplier.  NTK, I think and under $10.  I always ensure the part number is the same. 

Beenleigh Bearings last time, which I am sure TWB knows where they are. 

For those not familiar with bearing maintenance, always clean them first, preferably with white spirit, then repack them yourself with a bearing grease designed for their specific use.

I would have shoved till he started coughing.
These are as close as I have been able to find as a replacement for the OEM and they are 0.25mm narrower than the OEM. However it does the job and if you need perfection then make a spacer for the pivot pin.

Thanks Rick , that's worth knowing. I did get OEM bearings for the swing arm and they fitted up without problems.
I used NSK bearings for the steering head, and they seem fine.
I should still have the All Balls bearings in the steel scrap bin, I'll dig them out after work and post a pic so you can see the difference.
