have a super-hard titanium coating on the inner fork
tubes, green-anodized caps and a new silver finish on the
outer fork tube. As for the Showa shock, there are firmer
settings. Although not new, the Kashima coating on the
piggyback cylinder reduces friction, resists abrasions and
helps smooth out the suspension action. Additionally,
the shock spring is now green to match the other color
accents on the KX250F.
( 6) Axles. In an effort to shave weight, Kawasaki
changed the wall thickness on the front and rear axles
while maintaining the same outer diameter. They were
able to cut 31 grams out of the front axle and 32 grams
from the rear axle.
( 7) Styling. The 2015 KX250F comes with new
factory-style graphics, plus green engine plugs, oil cap,
generator cover plugs, as well as green alumite suspension adjusters and black alumite wheels. The shock body
has also been colored black for a works-bike look.
( 8) Rear axle nut. We’re extremely pleased to report
that Kawasaki has finally upgraded to a self-locking rear
axle nut. It maintains tightness without requiring a
( 9) Front brake. Kawasaki has at last beefed up its
front brake, upgrading to a 270mm, oversized,
petal-shaped, Braking front brake rotor. It replaces last
year’s 250mm front rotor. It is paired with a 240mm
Braking rear rotor.
( 10) Ergonomics. Several of the comforts afforded to
the KX450F have trickled down to the 2015 KX250F. The
bike now comes with a four-position upper triple clamp
with two sets of handlebar mount slots. These offer the
rider the choice of four bar positions, including 25mm
forward, 15mm forward, standard or 10mm back. Plus,
the KX250F has two-position, adjustable footpeg
brackets, which can be lowered by 5mm on the frame.
( 11) Subframe. The aluminum perimeter frame has
been updated in order to accommodate the adjustable
footpeg mounts. A new rear subframe is 50 grams lighter
for optimized mass centralization. This was accomplished
by decreasing the subframe’s inner thickness by 0.2mm.
Q: WHAT IS THE MOST IMPORTANT
UPDATE THAT KAWASAKI MADE TO THE
A: At the risk of sounding fickle, MXA test riders
loved that Kawasaki finally addressed some of the woes
that long plagued the KX250F. Although basic, the larger
Braking front brake rotor is a considerable improvement
over the antiquated front brake that came standard in
the past. The self-locking rear axle nut is also a treasured upgrade, because we were sick of dealing with
the pesky cotter key. Four-position handlebar mounts
are an advantage for taller riders, as are the adjustable
