Bad experience with BMW

I bought a new 2020 Gs1250 adventure on 20-05-2020 with the expectation that this motorbike can outlast and out run any other brand. I drive about 120km per day to do my daily duties so this is why I bought this bike. During this 3 years my bike was service at 10000km intervals at BMW Bavarian in Centurion. On 10 July 2023 five weeks after my warranty expire and on 80000km I heard a noise in the motor. I emmediatly took my bike to BMW Bavarian to check what is wrong. After investigation they discover that a bearing inside my gearbox is worn out. After fights and phone calls to Bavarian and to BMW south africa, they just turn their back on me and said that it's out of warranty and they will not assist me with this and that the millage is to high. So If I bought the bike 10 days later on 1 June 2020 I would have had five year warranty, they also told me if the bike broke down 5 weeks back regardless of the millage they would have fixed it. So according to my experience a BMW 1250GS cannot go past 80000km because your problems will start and BMW will just turn their back on you. I cannot believe that they just turn tier back an me and said sorry we cannot help with this. If they even just said that they can meet me halfway with the repairs I would have accepted this. All the BMW *****s out their make sure that you don't get caught in the same trap. Make sure you either extend your warranty or sell your bike before 80000km because BMW will just turn there back on you.
