No, it is not possible to start a Royal Enfield motorcycle with just your hands. Royal Enfield motorcycles, like most motorcycles, require a functioning electrical system and a kick-start lever or an electric starter to start the engine. The kick-start lever is typically used to start the engine by kicking it down forcefully with your foot, while the electric starter button is used to start the engine using the motorcycle's electrical system.
Starting a motorcycle with your hands alone, without the aid of any tools or the motorcycle's intended starting mechanism, is highly unlikely and not a recommended or practical method.
