Bike for trip to Mongolia

Traveling by motorcycle is my life. I live in beautiful country Croatia, which is in Europe. My biggest wish is to go in Mongolia by bike.. But my bike is little bit weak and old and I know that it can’t handle trip from 10.000 kilometers. If you want to help me to manage this, please send some 💶💰💷💵💴💳💎... I work 12 hours per day, but I just can’t make it and get enough money... Please, help 🙏🏻
