2010 KTM 690 Duke R
With the most powerful single cylinder
in the world, KTM continues to record the success
story of the Duke
The KTM LC4 model palette is legendary. What was set
in motion for 20 years ago in Mattighofen, Austria
with the development of a potent and sporty single
cylinder four-stroke motor has now resulted in the
company having a massive fan base.
Thousands of Endurists, Supermoto and
Street Bike riders all over the world swear by the
sporty single-cylinder from Austria that is so difficult
to overtake. KTM was able to further extend its leading
role with
the introduction onto the market in the spring of
2007 of a completely new LC-4 generation: the entirely
new engine that lifted the single cylinder to a new
level in matters of performance, rideability and Laufkultur
??. the LC-4 made its debut packed in the highly modern
690 Supermoto, which shone with its exemplary
consumption and emission behaviour.
In the following year KTM presented
the 690 Enduro, the 690 SMC, the 690 Supermoto R and
the new Duke – and with this, made a strong
commitment to the single-cylinder, LC4 principle.
As the latest proof or this conviction,
the commitment to the development continues with an
impassioned heart. At the EICMA 2009, KTM, with the
690 Duke R, presents the most powerful single-cylinder
of all times that is registered for the road –
the just 148 kg-light motorcycle comes in at 70 hp.
A sleek and sensationally agile chassis, fitted through
and through with high quality components and the extremely
purist
sporty Duke style completes the latest LC4 model.
Also in its strongest stage of development
KTM’s LC4 single is not only the most powerful
but also the most modern single cylinder in the world,
super reliable, extremely maintenance friendly and
with a singularly logical structure.
Thanks to the longer stroke (84.5 instead
of 80 cm) and the displacement expanded to 690 ccm
the 690 Duke R produces a juicy 70 hp top performance
and 70 Nm maximum torque, which is produced in a unique,
spontaneous and wonderfully cultivated single cylinder
manner. Thanks to the Electronic Power
Throttle (EPT) the motor management monitors the fuel
instructions of the rider.
Quite apart from this the LC4 belongs
to the most economical motor of all times. A nice
side effect and evidence of the high level of technical
competence: the series observation and tribological
refinements – like the further optimised surface
refinements through the use of a high abrasion fixer,
therefore an extremely scratch resistant DLC coating
– allows that from this model year, the inspection
intervals of all LC4 models
can be extended from the original 5000 km to 7500
km.
When it comes to the shock absorber
of the 690 Duke there’s nothing left to desire
– race ready high tech with a broad range of
adjustments, many possible settings and excellent
basic tuning – a component the likes of which
is being sought by the competitors. For the 690 Duke
R there is an orange powder-coated spring that matches
the racy “R” design.
However the already excellent fork
fitted to the standard model has been further refined
for the 690 Duke R: after extremely fine polishing,
its enormous warp resistant 48er inner pipe is coated
with a special scratch resistant and robust TiAlN,
which, together with a matching setting, ensures even
more grip and improves suspension sensibility.
Topic fork: Here carbon the carbon
fibre mudguard not only underscores the appearance
of the 690 Duke R; it also reduces the non-sprung
mass of the front wheel by over 300 grams. The interplay
between the light but still torsion-stiff latticed
tubular frame creates a chassis with a unique, one
piece, finned, latticed, die-cast swing arm and black
anodised triple clamps that is balanced, safe and
super-safe, which gives 148 km-light street robber
an unequalled riding dynamic.
Not just single cylinder fans but all
enthusiastic sports motorcycle riders find the 690
Duke R to be an unusual, reliable and arrow swift
guarantee for pure riding fun.

The New Bike With Added Sports Appeal
Since as far back as 1994, the name 'Duke' has stood
for fast, agile and unique powerhouses that cannot
be pigeonholed. For 2010, however, KTM is once again
adding an extra something with the new 690 Duke R.
As with all 'R' models, riders expect the 'R' design
to have an extremely powerful cocktail of sporty dynamics
and an athletic look. The 690 Duke R hits the spot
with its playful handling, high-precision riding characteristics
and low weight. Its sensational 70 HP single-cylinder
engine is the most powerful in the world and is integrated
into a rigid trellis chassis. KTM has equipped the
motorcycle with lightweight 17-inch wheels and premium
quality, fully adjustable WP chassis components with
TiAIN-coated fork inner tubes. A
Brembo four-piston radial brake system ensures excellent
deceleration. The carbon mudguard, the numerous black
components and the dark-coloured tail light highlight
the machine's special status as a motorcycle
that has been lovingly designed to meet the highest
quality standards... and that does absolutely everything
it promises!
