The idle RPM of a scooter depends on the make and model, but typically the idle RPM range is between 1,000 and 1,500 RPM....................................
Also make sure to change gears before hitting the 4000-5000 RPM mark on any bike for a smooth ride as well as a non-jerky and safe ride. This not only helps increase the life of the bike and give you comfort, but also helps extract the most fuel economy from the bike as well.
