A 125cc dirt bike generally hits a top speed of 60 mph. Consider this a top speed when racing Motocross or riding trails on a hardpack straightaway - the ideal setting for a dirt bike. However, if you must, on paved roads expect to hit close to 70 mph.
The manufacturer's test for speed may be performed under ideal conditions. The claimed top speed by the manufacturer may not be the same as the top speed recorded in an independent road test.
