I started on a zx6r, you’ll be fine on this too.
Trick that kept me safe was a buddy telling me to start with my wrist flat. People get in trouble because they reach way over the throttle with their wrist bent upwards meaning to open it to a comfortable flat position, and when the bike starts it rocks them backwards, completely opening the throttle accidentally.
Instead start with a flat wrist and instead of twisting your wrist to open the throttle just lean forwards. The change in arm position will naturally open the throttle and your lower body position will help keep you from sliding back anyways.
Awesome. Training courses are such a good idea, they should just be mandatory for all new riders. Definitely kept me from making dumb mistakes as a new rider lol.
