Its EXACTLY like riding a bicycle and driving a stick-shift car. Only difference is the location of the controls. You use your left hand for clutch, left foot shifts, right foot is back brake, right hand is front brake. Throttle is the twisty thing on your right hand grip. Just like a bicycle you dont jam on the front brake unless you wanna do a stoppie or a face plant
Check if you have a MSF course close by, MSF is Motorcycle Safety Foundation, there the best way to go about getting to know bikes the RIGHT way. Sure a friend can teach ya but he may not teach ya the shit ya need to know to be a good safe rider.
Bikes are a total blast and worth the effort to learn. Just keep yer head on yer shoulders straight and enjoy it.
