The 250 Xciting is very capable of 70 mph+, but the Tach runs in the red section, close to
8,000 rpm. I checked mine against the GPS and the speedometer does read higher than the
GPS, maybe 2-3 mph. 62-65 is pretty fair (Speed Limit is 62 anyway) at keeping the tach
rpm's within reason. Now my Grandvista (also 250cc) seems to run at 70 with less rpm's,
but this model speedometer runs higher than the GPS. More than the Xciting. The difference
in Tire Size probably accounts for this difference. My roads are relatively level with some
small hills and my trips are in the 1 hour (60-70 mile) range. Remember wind speed and direction
is always a factor.
