Can you start a motorcycle without a battery?

You could try this & it might work: Keep the ignition key in the "On" position, Press the clutch lever & get into 1st gear. Then run with your bike while keeping the cluth pressed. When you hear the engine splutter, let go of the clutch & hop onto yr bike & keep accelerating. Be careful not to lose balance when you are running with the bike, make sure you don't run into people or slip on sand. With some practice, you'll manage it.
