No official word on the top speed of Harley Davidson Street 500 has been given while people claim of touching 80 mph on their bikes easily. They even say that riding at 70 mph all day is easy and requires no extra effort. The 500 cc Street uses a V-Twin engine and produces around 50 Nm of torque at 3500 rpm. It uses the same 6-speed gearbox as the bigger 750 cc Street and retails in limited markets only. These models have been specifically made for Asia where traffic needs have forced people to use lighter and more economical bikes.
