I agree with Calothrix. When I had my People 150 (2010), the speedometer was about 10% optimistic. I weigh about 210, and could only get a GPS verified 59 out of mine. I also had a aftermarket exhaust system and 1 Gram (14) lighter rollers in the variator. The 150 is a great little scooter, but limited on speed. I traded mine for a GTI300 (2012) for interstate riding.
