2004 KTM Sportminicycles
- 125 SX
The 125 SX has developed to the motorcycle
of its class. With lively engine characteristics
and optimal cross-handling this motorcycle
is the best of many years in the world championship
and winner of the US national Championship.
By the use of a V-Force Intake System and
a new exhaust the performance is improved
significantly.
The 125 EXC is the introductory model to
professional Enduro sport. Developed by World
champions it has been the benchmark in the
125cc class for years.
V-Force Intake System offers more peak power
and better throttle response. New exhaust
pipe results in more midrange and top end
power.
