Harley-Davidson motorcycles, like many other motorcycles, are equipped with a safety feature known as a clutch interlock switch. This switch is designed to prevent the motorcycle from starting unless the clutch lever is pulled in. If you attempt to start a Harley-Davidson motorcycle without pulling in the clutch lever, the engine will not start.
The clutch interlock switch serves to protect the bike from potential damage that could occur if it were started while in gear without the clutch engaged. It prevents the motorcycle from lurching forward or stalling if the rider accidentally engages a gear while starting the bike.
In the event that you accidentally attempt to start a Harley-Davidson motorcycle without pulling in the clutch lever, no damage should occur to the bike. The safety feature of the clutch interlock switch will prevent the engine from starting, ensuring that the motorcycle remains stationary until the clutch is engaged.
