9.) The chain has a gold finish.
10.) The ODI lock-on grips are gray instead of black.
11.) It has a plastic disc guard for the front brake rotor.
12.) The suggested retail price is $9499, which is $1000
higher than the standard model.
The 450 has all the same features with the following
changes: The muffler is a titanium Akrapovic. The seat is
darker blue and does have a ritzy Selle Dalla Valle logo.
The graphics are styled after the Red Bull KTM team’s,
and the bike carries a fat number 1 to commemorate Ryan
Dungey’s 2016 Supercross championship. There’s a faint
5 superimposed on the 1 if you look closely. The 2017 1/2
450SX-F has a suggested retail price of $10,399—again,
$1000 over the standard version.
WHAT’S THE SAME?
Both of these bikes got
completely new motors and
frames in 2016, then new
suspension the next year.
The dual-overhead-cam 250
motor still has a redline over
14,000 rpm and more peak
power than any bike in the
class. When we ran all the
250s on the dyno for our 2017
shootout, the KTM was the
king at 45 horsepower. All
of the others (aside from the
were around 41 horsepower.
In weight, too, the KTM 250 was—and is—the class
champion. It weighs 218 pounds without fuel. The 450
motor was new in 2016, but it has the same features and
layout as the previous motor. It’s still a single-overhead-cam layout with a diaphragm spring clutch. Most of the
changes are aimed at weight reduction. Like the 250, it’s
the class champion in both horsepower and weight. Both
motors also got new electronics and a lithium battery in
2016. The 2017 models have a handlebar-mounted switch
that lets you choose between a standard EFI map and an
aggressive one. There’s also a traction control mode (for
slippery conditions) and a launch control (for starts only)—
all available through the same switch.
The biggest news for 2017 was the arrival of the WP
AER 48 air fork. It’s the most intelligently designed air
fork on the market, using only
one air chamber (in the right
leg) with no balance chamber,
cross-over tubes or unnecessary
At the risk of repeating what
we’ve been saying all year,
the two KTMs are incredible
bikes. Both won their respective
shootouts, and we had almost
the same experience riding the
Factory Editions as when we
rode the originals. Most riders
wouldn’t notice the difference
without a back-to-back
comparison. Here’s the short
The KTM 450SX-F is probably the best
pro 450 you can buy. Wait—it’s also the
best novice-level 450 you can buy.
