Motorcross newcomer

Aloha! I am Dome 19J. old and have some questions. I would like to drive motorcross and I already save for the driver’s license. In the field I don’t know at all and I haven’t driven so yet. Leisure time I like to ride mountain bike therefore I want to combine the mobility and the terrain suitability. What should I know as a beginner? I came across the Yamaha WR 125 R once while browsing the net and it should be beginner friendly. How much Bud What do I have to pay attention to when buying a used machine? How do you keep it in place and what is the cost involved? What can you tell me about the Yamaha WR 125 R so what is so good about the machine and what is not? Can you recommend other machines to me? Unfortunately, I only have the money to buy them and I estimate a budget of 2500 euros for the machine. The machine should be equipped with a machine that is suitable for the machine. ßen be admitted but also make fun in the terrain. If you have any other information or advice that a beginner should know, please also write it. Mfg
