seriously, do not, go on youtube... they already KNOW how to ride, yes they explain, but its not very good of a lesson. honestly just get on it and try, if you dump you dump. you'll know what to do next time. if you can ride a bicycle down the street without pedaling and you sytay up, you can stay up on a motorcycle, the wheels act as gyros and want to keep the bike upright anyway.
just know that the slower you go, the more its going to wobble b/c the gyroscopic effect wont kick in until about 10 mph. just ease into it if you hurry, you'll end up hurting yourself
