What should be noted when using the prop stand?

You selected all correct answers. When using the prop stand on a motorcycle, it is important to ensure the stand is fully extended so the bike is stable and will not fall over. Parking on a slope should be avoided whenever possible because the motorcycle could become unstable and tip over. Additionally, many modern motorcycles have a prop stand switch that prevents you from riding off if the stand is still extended, which helps avoid accidents. Remembering all of these points ensures both your safety and that of your motorcycle.
