My tach records the highest engine speed after a ride.
Don't recall going over @38MPH indicated, on my sunrise coffee ride today.
I
did have to get frisky twice at uphill stop lights.....so.
Max engine speed is 7,500RPM; max torque at 6,500RPM....(per cyclepedia)
They have the fountain back on downtown.
Moon was setting quickly on the ride in....
