The Red Bull KTM team doesn’t want anyone to know that
Dungey uses a Honda steering stabilizer. It’ll be our secret.
It’s hard to tell that behind the magnesium and aluminum is a
powerplant that cannot be bought for any price.
valves, would make any gear-head beam from excitement.
For the MXA wrecking crew, it doesn’t get much better
than the WP SXS Trax shock. It features not only high-and low-speed adjusters, but is equipped with KTM’s
unique dropout feature. Follow along as we explain the
intricacy of a system that has been around for years but
has been mostly an industry secret due to its stealthy
appearance. What is a dropout shock? Internally, the
shock speeds up the rebound when the rear wheel is off
the ground in order to settle faster and allow the rear tire
to maintain better contact with undulating ground. As
soon as the wheel leaves the ground, a valve opens to let
the shock extend. It’s designed to work in small chop and
braking bumps while still compressing fully and allowing
the spring to take the brunt of force over large hits. The
Trax shock system has been revised recently to allow
the rider to “lock in” the dropout feature depending on
the track. Dungey didn’t use the dropout in Supercross,
because it had negative effects on the shock when
clipping jump landings or under a heavy load. He is
selective on which tracks to use it outdoors, preferring
the dropout design on tracks where traction is at a
premium, such as Hangtown and Glen Helen.
WHAT’S THE MOST UNIQUE PART ON
DUNGEY’S BIKE? We were surprised to discover that
Ryan Dungey uses a steering stabilizer. However, wipe
any idea of a bulky and obtrusive Baja-style stabilizer
from your mind. Instead, the KTM team uses a Honda
HPSD stabilizer that comes stock on any late-model
CRF250 or CRF450. Carlos Rivera mounts the upper
stabilizer arm to a bracket located on the head tube,
with the lower arm affixed to the bottom triple clamp.
The 22mm Neken triple clamps with HPSD mounting
post are designed especially for the team. Dungey runs
solid, 40mm-tall bar mounts with a Renthal 821A FatBar.
Known as the McGrath/Short bend, the 821 has very
little sweep and sits low. The “A” is ever so slightly
different from the standard 821 and is handpicked off the
production line for Dungey. It is then marked with an “A”
and sent to the Red Bull KTM team. A customer cannot
buy the 821A, though it is so similar to the standard 821
that most riders wouldn’t notice a difference.
HOW MUCH DOES DUNGEY’S BIKE WEIGH?
We know what Dungey’s Red Bull KTM 450SXF Factory
Edition Supercross bike weighed, because it was
dangerously close to breaking the AMA’s mandatory
weight limit. Carlos Rivera regularly weighed the KTM
throughout Supercross to make sure that it was over the
220-pound limit. Carlos says that the weight fluctuated
between 221 and 222 pounds, though at times it just
passed by the skin of its shrouds. Why? To quote Rivera,
“Depending on the Supercross track, sometimes the
knobs would rip off in the main event, which dropped
the overall weight of the bike.” Race teams are always
searching for ways to lessen unsprung weight and
get their 450 bikes close to 220 pounds; KTM has the
opposite problem, thanks to their Factory Edition 450SXF.
WHAT ARE THE DIFFERENCES BETWEEN
DUNGEY’S SUPERCROSS AND OUTDOOR BIKES?
Carlos Rivera was quick to point out the lack of major
differences between what Ryan Dungey raced to the
2015 Supercross title and what he is riding outdoors.
Rivera says that Dungey was so impressed with the
race package that he hasn’t varied much in bike setup
over the course of the 2015 season. Then again, winning
eight Supercross races and finishing on the podium in all
