THE 2013
The above components resulted in a history-making moment for KTM
Motorsports after Red Bull KTM Factory Team athlete Ryan Dungey
won the first premier class championship aboard the company's most
noteworthy motocross machine, the 450 SX-F Factory Edition. The
2012 450 Motocross Championship marked the first championship
for the KTM brand but the fifth title for Dungey. The Minnesota native,
hand-picked by Team Manager Roger DeCoster, will return for the
2013 season as the team’s premier class rider in hopes of claiming
two more championships to his name.

Dungey returns on a mission to pursue the 2013 Supercross class title
as well as defend the #1 plate in the outdoor series. His bike of choice
will remain the 450 SX-F Factory Edition, a bike fine-tuned to handle
every obstacle, every corner no matter how tough. A collaboration
between the Austrian and North American based Research &
Development teams has helped launch the new 450 SX-F Factory
Edition as the leader in its class. A motorcycle that is built with racing
as its main objective with significant input from Dungey and his team;
a rider will not find a better machine. Dungey will commit himself to
another challenge this season always pushing the bar when it comes
to his training in the gym and on the track to bring to the team the
determination and fitness needed to prevail. His team will commit to
bringing him the best, most reliable machine to the gate each weekend
for 29 races. Forever committed to succeed, Ryan Dungey, his Red
Bull KTM Team and his 450 SX-F Factory Edition are “Ready to
Race”, are you?

Cylinder Head
The 2013 450 SX-F Factory Edition
engine cases and clutch cover have
been redesigned to minimize weight
by removing the kick starter boss to
save over 0.5lb and further reinforce
the effectiveness of KTMs electric
start system for racing. The DDS clutch
has also be updated with a new
280Nm spring that has been tested
and proven by Ryan Dungey during the
2012 Outdoor National series.
The design of the 2013 cylinder head allows
for maximum power output thanks to its
ports, combustion chamber and valve train.
The lightweight titanium valves and
lightweight design of the rocker arms (intake
rocker arm is sliding on a DLC coated contact
directly on the cam shaft) allow for the rpm
limit of 11,500 rpm and a high power output
of 60 hp.
PISTON & CylindeR
Counter Balance Shaft
In the 95mm bore of the cylinder a weight optimized
König piston with a stiff box-in-box design provides a
compression ratio of 12.6:1.
The new 450 engine is fitted with a laterally mounted
counter balancer, which at the same time drives the
water pump. This solution allows a very compact and
lightweight engine design.
- Weight optimized exhaust rocker
arms (intake DLC coated slide contact)
»low oscillating mass for high rpm
- Stiff rocker arm axles with integrated oil
jet for lubricating the intake cam
»safe valve activation
- Titanium intake and exhaust valves
»minimum masses for high rpm
The lightweight PANKL crankshaft with a stroke of 63.4
mm is fitted with a Pankl connecting rod featuring a
pressure lubricated plain bearing (no more needle
bearing), which allows a high rpm limiter and doubles
the time between maintenance intervals.
A lightweight electric starter is standard equipment
and provides a major advantage, especially when
restarting after a crash.
- Ultra-light valve springs and retainers
»precise valve timing
- Weight optimized camshaft
with optimized timing
»wide power band, high performance
DDS Clutch
The DDS (Damped Diaphragm Steel) one-piece clutch basket
combined with the primary gear is made of high-strength steel.
It guarantees unbeatable reliability and contributes to the
narrow engine size due to its compact rivet-less design.
Additionally, it allows the use of thin steel linings, which makes
the whole clutch package compact. A diaphragm spring makes
it possible to implement an additional rubber damping system,
guaranteeing reliability for the transmission and good traction.
The hydraulic clutch by Brembo, in conjunction with the
diaphragm spring, guarantees a light operation and controllable
modulation of the clutch. The clutch spring is 280 Nm
compared to 250 Nm (MY2012) for improved performance.
A 5-speed transmission to perfectly suit the 450 cc
power plant and provides easy and precise shifting.
2013 450 sx-f factory edition
The 450 SX-F Factory Edition is fitted with
the 827 Renthal Fatbar handlebar complete
with bar pad and new 2-compound grips
with KTM logo to provide excellent contact
to the bike.
Airbox design provides more space for the
airfilter for better airflow and reduced dirt to
the filter. The exchange of the TwinAir airfilter is possible without the use of any tools.
Bodywork is reworked to further improve the
bike ergonomics with slimmer, in-mould
graphic shrouds that provide a comfortable
feel and great contact with the bike.
FRONT Suspension
Rear Suspension
The linkage rear suspension with WP shock
absorber allows for individual clicker adjustment of the high/low speed compression as
well as rebound damping.
Aluminum cast swingarm provides perfect
stability at a minimum weight. The swingarm
is reinforced in the rear part of the arms to
improve stability and safety. The 25 mm highstrength rear axle allows for more track
The 48mm WP closed cartridge fork features
excellent control and bottoming characteristics
while maintaining comfort. The SKF seals and
SAE 4 fork oil provide the highest levels of
quality and performance.
Cooling System
The radiators made by WP RADIATOR provide
more durability and resistance to structural
damage in the event of a crash.
Industry leading Brembo brakes with stainlesssteel braided lines and oversized rotors provide
the best in braking performance.

THE 2013
Please tell us about the 450 engine, and your favorite benefit of that motor?
DeCoster: We all know that KTM has made ultra-strong engines throughout its existence, and the new 450
SX-F Factory Edition motor is no different. The engine produces massive power, and the best part, is the
power is delivered in a smooth and controllable manner.
Dungey: I feel the power range on the motor is solid throughout. It has great bottom, mid and top end
power. I truly feel it gives me an edge over the competition.
Please describe the 450 chassis and your favorite attribute of the chassis?
DeCoster: I still feel that a steel chassis is more compliant than the aluminum chassis, and in reality, the
aluminum chassis are the same weight as the steel chassis because they need to overbuild aluminum
frames in order to have the durability needed for the customers. I feel the chassis of the 450 SX-F Factory
Edition is a step above the competition.

Dungey: Overall the 450 SX-F Factory Edition has unbelievable handling. My favorite attribute is definitely
the chromoly steel frame. It is amazing what a difference the steel frame makes.
What involvement have you had in developing the new 450 SX-F Factory Edition?
DeCoster: Our race team (Red Bull KTM Factory Team) was heavily involved from the very beginning of the
production of this unit. It was the best joint effort between a race team and Research and Development
Department I have experienced since I was involved in the development of the CR’s for the start of AMA
production rule back in 1986. Both the Austrian and North American based R&D teams worked collectively
with our race team to ensure the bike was built with the racer in mind.
Dungey: I have basically been the test rider for the past two seasons. All of my feedback and that of the
Red Bull KTM team has been incorporated into the design, feel and overall handling of the bike. Also, a lot
of parts used on my factory bike are a part of the Factory Edition bike.
How does it feel to be so closely involved in the development of a new unit
for the U.S. market?
DeCoster: Of course, it feels great when things turn out as well as it did with this bike. It would be great if
we could always hit every target as well as we did with this bike. The media attention, consumer feedback
and race results have all spoken well to the benefit of this unit and what it is capable of.
Dungey: I’m proud to have been given the opportunity to, not only race for the Red Bull KTM team, but to
have an integral role in the development of the new bike. Knowing that my thoughts and feedback in
regards to performance and handling have been taken into account and incorporated into the new bike
design is a great honor.
