If the Frost is the Yager GT 200i here in the states, then it’s 175cc. The 200 in the name is just BS from Kymco. I would take mine up to 60 - 65 mph depending on the terrain and redline it just a little, and for short periods of time. If the bike is in good shape -- tires properly inflated, and not overloaded, it should get you to 60 and ride the line.
That was my experience with my former bike.
