Although KTM has changed their axles
sizes, front and rear, over the years, but
that doesn’t mean your old wheels are
MORE LIFE FOR SPARE
I have a spare set of KTM wheels
left over from my 2013 KTM 450SXF.
I just bought a 2015 KTM 350SXF,
and my spare front wheel won’t fit.
It turns out that KTM switched from
the big 2013 axle to a much smaller
front axle. Is my perfectly good spare
KTM front wheel useless now?
No. Most KTM racers went
through this same scenario in 2012
when KTM changed from its 20mm
rear axle to a 25mm rear axle. For
2015, they dropped the previous
26mm front axle for a smaller 22mm
axle, which allows them to change
the trail without changing the triple
Your old wheels will fit on your
2015 KTM, but you have to change
out the wheel spacers. Unlike a lot
of motocross bikes’ wheel spacers,
KTM’s run on the bearings, which
means that the front and rear will
accept different axle sizes by just
changing the wheel spacers.
You can order 2015 front wheel
spacers from your local KTM dealer
or just switch the wheel spacers
from your 2015 bike back and forth
between the stock wheels and
your spare wheels. You remove the
spacers in much the same way as
a steering bearing race. Just stick a
T-handle or long punch through the
hub and hit the inner lip of the wheel
spacer to knock it out. (They aren’t
a tight fit, so they will come out
easily.) Then swap the 2015
spacers over to your 2013 front
wheel. The lug-to-lug gap is different
on the 4CS forks from what it was on
the previous WP bladder forks, but
have no fear, the 2015 wheel spacers
will take up the gap.
Riders who have aftermarket
wheels that use the stock KTM wheel
spacers can easily convert them using
the same method; however, if you
have aftermarket wheels with proprietary wheel spacers, you will have to
send them back to the wheel builder
to have new spacers installed.

Pop the old one out
and the new one in.
