Are you sure that the statistics you looked into take into account number of vehicle on the road and miles/minutes traveled for each category?

Smaller bikes/scooters (you can drive them with a car license in my country if they are under 50cc) have a max top speed of 50km/h (31mph).

On the other hand, one of the most popular motorcycles (Yamaha MT-07) does 0-100km/h (0-60 mph) in under 4 seconds and can reach speeds of over 130 miles per hour. There is a lot that can go wrong if you are not careful. Also, it is almost twice as heavy.
