Those 110cc semiautomatic 4 stroke r1 bikes are very very slow. Slower than stock 50cc cag. They are heavy, big and awkward. Waste of money.
Displacement (CC's) isn't everything. And yes euro pocket bikes go 10 times as quick as chinese ones. The Chinese ones are poorly built replicas made of recycled tin cans put together in mass production by kids. Chinese engine design rarely improves, take a water cooled Z1 engine for example, in most cases these engines seize because of the little end bearing is not suitable. The chinese cant even COPY a engine without it being horrible, let alone make something that wil be better than a euro product.

Euro > Chinese
