how many rollers are in the flywheel side bearing on an '07 PX125
just stripped an engine down after seizures, and this bearing cage had collapsed.
obviously will be replacing the bearing, but until I get a new one, it'd be good to know that none escaped and fell into the rest of the engine as I split the casings, as I wasn't planning on taking it apart any further.
I have retrieved 22 rollers so far...

The crank area is sealed from the rest of the engine (gearbox-clutch) so it would be very difficult for anything to get to the bottom end, unless it finds a way through the clutch side oil seal and bearing...

yes, but the rollers all fell out as i was splitting the casing, so could have fallen in the gap into the cogs...

Just counted bearings in 3 engines I have stripped incase there was any variation.
Bad news Im afraid...23 needle rollers
