While it is generally recommended to start a Harley-Davidson motorcycle in neutral, it is not an absolute requirement. Starting the motorcycle in neutral ensures that the bike doesn't lurch forward or jump unexpectedly when you turn on the ignition. This can be particularly important if you have the clutch engaged or the bike in gear.
If you start the motorcycle in gear with the clutch lever pulled in, the bike should not move forward. It's important to keep the clutch lever engaged until you are ready to begin riding.
Starting the motorcycle in neutral is often suggested as a best practice because it reduces the risk of accidentally engaging the clutch and inadvertently moving the bike. It also helps prevent stalling the engine, especially for novice riders who may not be as experienced with clutch control.
Ultimately, whether you start your Harley-Davidson motorcycle in neutral or in gear with the clutch lever pulled in depends on your personal preference and comfort level. Just remember to always exercise caution and ensure that the clutch is engaged if you start the bike in gear.
