just get rid of arcade mode right off the bat.. itll be tricky and youll fall over a lot but dont get frustrated and you'll pick it up. set your stability really high, like 85, and when you can start going a little bit without falling so much, keep it lower.
Mines 20 right now. Someone thats never played literally cant go 10 ft down a straight with a stability of 20 lol... its tough. Biggest thing for this game is time. Its definitely not a game for anyone to just pick up and go like mx vs atv alive or anything. patience, and sometimes slower is faster. and think of it as a real bike... you cant just go wfo weverywhere. youll learn to brake and ease on the gas and stuff. no just pin and go!
