Street Triple 765 Headstock / Steering Bearing

Has anyone actually replaced or looked at their bearings in the headstock? I'm rebuilding an '18 and cannot get a clear answer on whether the supplied outer race of the new bearings are to be installed. I took the bike apart myself and there are no inner races installed from the factory, it appears. They are, however, supplied in the bearing packaging for T3800091.

We have the power to rebuild her.

If by 'inner race' you mean the part that fits in the headstock, that piece is usually press fit into the headstock. Unless there is obvious damage, I would not replace the lower one as it's usually hard to get out and worse to get back in properly. The top one may pop out easily. And I would not try to change the lower bearing myself unless you have a press. It's hard to get off without damaging the steering stem and harder to get back on without damaging the bearing. If you do, put the steering stem in the freezer over night and the bearing on a hot plate for a while. Don't use the oven; you'll never get the smell of grease out of it.

Appreciate the advice. I have to replace them as the bike was wrecked. That's what's odd to me, there was no separate outer bearing race installed in either the upper or lower portion of the headstock. There were inners on both upper and lower, but I replaced the whole stem as it was damaged. I'll post a pic for further clarification.

Thank you NEPA for posting the service manual pages!

Update to this. The outer races were in there. There was so much grease from the factory that I couldn't see them. Wiped a bunch of grease off, tada.. Facepalm..
