As with any stop, when you come to a stop on a hill, your primary concern is with making sure you have the clutch fully engaged and the throttle closed. On a steep grade however, there is the obvious risk of rolling backwards, and as such, it is important to make sure that you apply and maintain pressure to the brakes even after you come to a complete stop. Since your right hand will be used to apply the throttle when it comes time to get underway, it is easiest to use the rear brake to hold your position on the hill. With the bike at a standstill, the best way to then maintain your balance is to take your left foot and plant it firmly to the ground. As soon as you are ready to get rolling again, begin to disengage the clutch slowly until you feel the friction zone; it is in this area that you will just slightly feel the bike want to creep forward. As you do this, you can begin to apply a little throttle. Continue to disengage the clutch, and you will begin to feel it work against the rear brake. It is at this point that you can release the brake and apply the throttle as necessary to move forward. As you already probably know, no two hillsides or streets are the same, and there will come a time when to your left is a patch of gravel or object that won’t provide stable footing. If you find yourself in this predicament, you will need to apply the front brake and use your right foot to maintain balance. This technique will require more skill, and in turn, more practice because it forces you to use your right hand to both keep pressure on the brake and apply the throttle.
