Ball bearing crankshaft failure

Well, my 2013 DS 450 MX Engine is gone. With 130 hours failed, but could be worse. 09 engine lasted about 190 hours when I've changed the piston and timing chain. Stock motor.

I've heard a sound a metallic sound at idle speed and running and I thought was the header pipe making rattle noise, but not, was inside the engine. Lucky I stop immediately.

Dealer opened the cases and watch the right ball bearing failed causing the noise. Just one ball bearing is out and just a little of shavings or chunks of metal, that makes the piston has little scrathes, no problem after all, because after 130 hours is time to change.

The rest seems ok, gearbox, valves, cylinder, etc. The connecting rod is also ok, but will change the bearing of crankshaft and equilibrate, conrod bearing is named? for precaution.

Here's the photos:

Any recommendations or advice? :fingersx:
