Unlike the US, Europe's motorcycle licensing rules are much stricter, and require young riders to adhere to a tiered licensing system. The A1 class is where most youngsters start, and it entails riding a bike no larger than 125cc, with an engine that produces no more than 15 horsepower. This particular segment of two-wheelers is really interesting, as it's full of small bikes that mimic their larger, more powerful counterparts.
