When stopped on a hill, what is the safest way to start a motorcycle moving forward without rolling backward?

1. Pop the clutch and snap the throttle
2. Hold the front brake (or rear) to prevent rollback, find the friction zone with the clutch, roll on smooth throttle, and release the brake just as the bike begins to move forward
3. Use only the front brake the whole time
4. Let the bike roll back and use momentum
