30% less longitudinal stiffness
in the never-ending quest to
better absorb the energy from
rear wheel loads. The steering
head is steeper by four degrees
and the upper engine mounts
are now laterally attached. The
overall wheelbase is 10mm
shorter than 2016. Some of the
2017 weight savings comes from
a smaller and lighter subframe.
As we mentioned, the WP AER
48 air fork is now standard and
saves an impressive 3.6 pounds
in comparison to last year's 4CS
fork. Standard air pressure is
149 psi (10.2 bar). The new air
box is home to the new air filter
and filter support system. It is
even easier to change an air
filter in 2017. Since the KTM 250
SX shares the same ergos as
the four-strokes, the seat height
is now 10mm lower through
the middle and 20mm lower at
the back of the seat, creating a
lower center of gravity. The new
radiator design increases cool-
ing and overall strength.
The 250/300 two-stroke
engine is the most produced en-
gine at the KTM factory. It finds
The 250 SX is
fitted with what
we feel is the best
production air fork
out there—the WP
AER 48.
