A: There are no changes for 2017 that are unique to
the 250SXF. The 10 major changes on the 2017 250SXF
are also found on the 350SXF and 450SXF. Here is the list.
(1) Air forks. WP AER front forks replace last year’s WP
4CS forks. The WP air forks are a big contributor to the
KTM’s astonishing performance—and it’s unprecedented
lightness. KTM supplies a digital air pump with every bike.
( 2) Shock spring. Last year the 2016 KTM 250SXF and
Factory Edition came with the 45 N/m shock spring. This
year the 250SXF gets a more appropriate 42 N/m spring.
In fact, every 2017 KTM motocross model will get lighter
spring rates. The 450SXF is spec’ed with a 45 N/m spring.
The 350SXF, 250SXF and 250SX two-stroke will come with
42 N/m springs, while the 125SX and 150SX are spec’ed
with 39 N/m springs.
( 3) Map switch. Gone is the flick-style selector switch
that toggled back and forth between two maps and activated launch control. In its place is a multi-switch on the
left side of the bars that toggles between two maps, launch
control and traction control.
( 4) Traction control. New for 2017, KTM has added
a traction-control feature to the electronic package on the
( 5) Brake pedal. The rear brake pedal is now 10mm
longer than it was in 2016. Owners of 2016s can order a
10mm-long brake tip from 7602 Racing that does the same
thing. Retail price is $34.95 at www.7602racing.com.
( 6) Rear brake pads. For 2017, the rear brake pads
have a less-aggressive compound. Many racers felt that
the previous rear brake pad was too grabby and could
overheat if used too aggressively; however, if you liked last
year’s brake pads, they retrofit.
( 7) Head stays. Last year’s steel head stays have been
replaced with thicker and stiffer cast-aluminum stays that
are 60 grams lighter.
( 8) Triple clamp. The top triple clamp is more rigid
in 2017 than it was in 2016. It is designed to mate better
with the flex characteristics of the air fork. The difference
is noticeable in that the machined hole in front of the steering-stem bolt has disappeared.
( 9) Hour meter. There is an hour meter installed on
every KTM. It is located neatly behind the front number
plate in the spot where the hole used to be in the top
( 10) Handlebar clamps. Last year the bars were
mounted to a one-piece lower bar mount with two separate
top bar-mount clamps. For 2017 the bottom bar mounts
are now two separate pieces, while the top bar mount is
one piece. KTM says this will prevent twisting. We didn’t
notice a lot of difference.
Q: WHAT DID WE HATE?
A: The hate list:
(1) Gas cap. It sticks. We’ve had test riders who
couldn’t get it off at the gas station.
( 2) Exhaust. Removing the stock exhaust requires several annoying steps, including removing the shock.
( 3) Sprocket bolts. Watch them for as long as you
own the bike.
( 4) Spokes. Always check the spoke next to the rear
rim lock. If it is loose—and five times out of 10 it will
