DeepL works quite well
They criticized the brakes and the clutch
Had many problems with the the brakes with rear and front calipers replaced, as well as the front master cylinder
and at 20000km they observed consumption of the front brake disc ("brake disc had already lost 0.25 mm of its original thickness (5.02 mm). Although 50 percent of the wear limit of 4.5 mm is still missing, the brake pistons do not seem to completely compensate for the additional working distance")
cold start issues
Chain set changed at only 20000km (20000km service cost was 773€)
new chain set at 40000km, jointly with steering head bearing and the starter free-wheel
Engine failure (The connecting rod bearing had run in) happened at 47000km and surprisingly
"BMW sent a technician to Stuttgart for this purpose. The engine of the G 310 R was dismantled by the BMW technician in the editorial workshop in the presence of us. Cause: The connecting rod bearing had run in. Since the rest of the engine interior still looked good, the connecting rod and bearing shells were exchanged and the engine was reassembled and sealed. The parts are currently being inspected at the factory, while the engine is being returned to the chassis.
Too many faults in my view, and luckily no alternator issues or cush drive rubbers to be replaced
Basically, my idea of poor braking system is confirmed.
Surprising for me how a low power engine requires substitution of chain set every 20000km (typically 40000 km on bigger bikes)
This jointly with other problems makes maintenance much expensive than expected...
