So, what kind of license would you need if your bike was bigger than 125cc? Like 1175cc bigger.
If you were a visitor you would just need your American motorcycle license and an International driver’s license. If you wanted to live here you would need a class A motorcycle license and, since you are an American, you would have to start from scratch. Sign up for a driving school, take your written exam, driving lessons and a practical exam. Doesn’t matter if you’ve been riding for 5 years or 50.
