ICE motorbikes are a lot of things, but they’re far from efficient, unless you’re referring to low power bikes which use around 2l/100km (120 mpg).
Anything at least slightly sporty uses about 3 times as much, which brings it into small car territory (while being smaller and weighing considerably less).
By comparison, electric motorcycles use about 40 to 50% of the energy that an electric car needs. Motorcycle ICE engines are optimized for power in a small package, not for efficiency.
