A vehicle`s maximum speed is dependent on many variables. Winds,
temperature, altitude, tyre choice, fuel load, rider/driver
weight, factory speed regulators (set for different countries),
varying emission controls (set for different countries), etc
all contribute to maximum speeds.
The maximum speeds given are compiled through manufacturer`s
specifications and a variety of literature. Where varying maximum
speeds have been found a sound average is given as an estimate
(est).
