Replacing Races For New Triple Clamps?

I have not replaced races with new triple clamps? What brand triple clamps? 

Interesting. I'm sure someone with more knowledge will chime in. I have seen what you are talking about, but never experienced needing to do new races. 

What a pain in the ass....

Ride clamps use All Ballz bearings to save on costs, and they're a different size than stock. You must change the races to use them, or upgrade them to an OEM bearing.

This is why we only use high quality OEM bearings on our products!

To answer your question:  With a new bike, no you don't have to..  30-50 hrs I would 

If you're this far in, bike all ripped apart and clamps removed, swapping the races in minor in the grand scheme of things.

Well, yes.

But a company putting on Non std bearings, to save costs, Without the commensurate 'races' , that they leave to their customers to acquire,  is , to me, not confidence inspiring in said company.

With regards to the 'races' referred to : are they , what I'll call, the 'female' part of a  Tapered bearing, or, is the Entire Bearing supplied with the clamps, of such a different OD or Depth (I assume) that it has to have an additional insert / 'race' fitted to enable use of the different bearing? 

Whatever it is, it really seems dodgy to me, to Not use the std Sized bearings. 

If your new bearing race/cup and the one in your chassis is the same spec, you’ve got good grease maintenance habits and there is no sign of wear or damage to the already installed race then it makes 0 sense to change it.

As mentioned by Luxon, the all-balls bearings are a different spec to stock so in this case you have to change the race/cup or the bearing on the clamp. In your position I’d change the bearing on the clamp as it keeps everything the same spec as stock.

Best thing to do would’ve been to either buy a new oem bearing and remove the shit all balls. Or press the bearing off oem stem, press bearing off aftermarket stem, and install oem bearing onto aftermarket stem. 

Yes that's normal I have ride engineering 22 mm offset triple clamps for my 23 KX 450 and I replaced the races and it gives instructions to do so basically you just punch it out with a long punch and Hammer then use your old bearing turned upside down two Hammer the new race and evenly tap it to the bottoms out you'll hear the pitch of the hammer blow change once it's bottomed but yes that's normal I had to do the same thing with mine no big deal and pretty easy to do

Races are super easy to manage with the right tools. Just do it.

As far as the All Balls vs OEM bearings, I've ran the OEM top and left the All Balls lower on a couple sets of RE clamps. Top bearing/race always goes bad for me first anyway, regardless of brand. Your mileage may vary.
