Only the best power, performance and appearance are
good enough for first place: the KTM 50 SX – a
winner for every ace from the ages of six to nine. The
seat height is adjustable from 650 mm upwards, with
long suspension travel, disk brakes at the front and
rear, a chain guard, as well as the best power output
available in this class.
And getting off it? Yeah okay, but only when the tank
is empty.
