What type of motorbike is best for beginners?

the best type of motorbike to start with is prob a100cc so you can learn the basics of a motorbike .like the controls and riding safe and confident (but you be better going to trainning school )then you can gradually get a bigger bike once you get experience and confidence on a motorbike .but after a 100cc i suggest a 250 cc cos you dont,want to go to a 750cc +bike cos it be to powerful for you and we don't, want you to kill yourself
