Newer ST's don't have pipe drain hole like first models.
Oil can acumulate inside pipe if you ride for long periods slow. If after that, you ride it hard (uphill open trothle for long periods) it can ignite "gum oil" inside pipe and get very hot with a lot smoke. I think this hapened with me when bike melted rear fender.
Have someone tried Maxxis trialmaxx (KTM freeride OEM) tire on trial conditions yet?

how do they hold?
Jitsie sell this tools.
Yes, it is overkill for who change bearings of one bike 4-5 times in a decade. But your mechanic has to have one...if not, run away.
My answer is a expanding mandrel.
Fit the mandrel in bearing
Put the expanding rod from other side
Hit it with a hammer
The bearing will exit centered. This is important to not enlarge hub hole
To fit new one, you will need a tool to keep spacer centered and apply force centered only on external ring
90 psi and turn the part you want to fix red hot with a torch.....use a pressure regulator to maintain pressure constant since it tend to increase when you heat the carbon inside (burn most you can before), use thick gloves, face shield and all proctetive equipment you have since it is something dangerous.
