==Engine==
The engine was a Liquid cooling system, continuous circulation of cooling liquid with water pump cooled Four stroke, single cylinder, DOHC, 4 valves per cylinder. The engine featured a 12.5:1 [[compression ratio]].  

==Drive==
Power was moderated via the Wet multi-disc clutch, mechanically operated.  

==Chassis==
It came with a 110/70 - ZR17 M/C 54W TL front [[tire]] and a 150/60 - ZR17 M/C 66W TL rear tire. Stopping was achieved via Single 300 mm disc, 4 piston caliper in the front and a Single 230 mm disc, 1 piston caliper, floating in the rear. The front suspension was a  WP-USD Ø 43 mm. while the rear was equipped with a WP-Monoshock. The 250 Duke was fitted with a 11 L / 2.9 US gal / 2.4 Imp gal fuel tank. The bike weighed just 139 kg / 306 lbs. The wheelbase was 1367 mm / 53.8 in long.

== Overview ==
KTM Duke 250











KTM unveiled its RC250 and Duke
250 at the 43rd Tokyo Motorcycle Show.
Here are the engine specifications of both
RC250 and Duke 250 that share a common engine:

Engine: 250cc single cylinder, liquid-cooled
Horsepower: 31.3
Torque: 24 Nm
Gearbox: 6-speed

The engine for both RC250 and Duke 250 has been derived
from its older sibling Duke and RC390 motorcycle. KTM engineers have detuned
their 373.2cc powerhouse to perhaps provide a more rideable sportbike on the
streets of Japan.
As a result, we expect taller gearing, better or same
efficiency and top-level performance. KTM is famous for making insane power to
weight ratio machines and it has done so right this time too. The Duke weighs
139 kg and RC 250 weighs 147 kg, which is 3-4 kg heavier than their 200cc
predecessors when you compare their dry weights. The engine weighs 37.2 kg and
is the lightest in its class. The motor is a 4-valve, DOHC, liquid-cooled unit
with Nikasil coating on the cylinders
The trellis chassis and WP suspension system continue to
be the norm making the newest KTM duo very attractive. These machines with their
basic hardware have impressed everyone. The motorcycles would be manufactured at
Bajajs plant in Pune alongside its siblings and come fitted with ABS (as seen
in the pictures).



Engine
KTM 250 DUKE's state-of-the-art, single-cylinder engine once again
underlines KTM's development strength. It's clear that the latest
materials and production technologies not only deliver the bike's
bountiful torque and overwhelming acceleration at all engine speeds,
but also good manners in everyday use and outstanding fuel economy.
With 249 cc, the single-cylinder engine only weighs 36 kg, thanks to
the compact design - typical of KTM - with transmission shafts
arranged one above another. Moreover, it delivers a punchy 31 hp
with such technical refinements as forced oil lubrication with
performance-boosting casing evacuation (the suction pump not only
transfers oil, but also pressure from the crankcase, thereby
reducing the running resistance of the crank drive).

Cylinder Head
Just as on the RC8 R, the four valves in the cylinder head of the
250 DUKE are actuated by two overhead camshafts and cam levers. This
design is not only extremely reliable, but also very durable and
almost frictionless, thanks to the ultra-hard carbon coating of the
cam levers - releasing even more power.

Slipper Clutch
The anti-hopping wet clutch makes perfect getaways from the traffic
lights simple with its precise, light and easy action.
Silencer
The compact, three-chamber silencer is positioned close to the
bike's overall centre of gravity. This aids the centralisation of
masses and enhances the playful handling of the 250 DUKE. Thanks to
a regulated catalytic converter, the emissions are exemplary.
Injection
The intricate engine design, state-of-the-art injection electronics
and the close-ratio, six-speed transmission not only help the KTM
250 DUKE to achieve impressive performance, but also extremely low
fuel consumption. Thanks to the regulated catalytic converter, it
produces only minimal emissions.

Fuel Tank
The shapely 11 l fuel tank of the 250 DUKE not only provides the
rider with perfect knee contact, but also with a greater range, even
when ridden on the edge, thanks to the economic engine.

Brakes
A state-of-the-art Bosch 9MB ABS makes the pleasure of the
impressive Duke dynamics even safer and adds the finishing touch to
its peerless chassis qualities. The ABS on the KTM 250 DUKE monitors
the effect of the potent brake system with radially-bolted,
four-piston caliper and 300 mm disc diameter - fun with no regrets,
developed in close collaboration with the specialists from Bosch and
Brembo. And for the stunt riders among us: the ABS is naturally
disengageable.

Frame
23 kW (31 hp) power plus a dry weight of only 139 kg guarantee
immense, agile riding fun with the new 250 DUKE. The first-class
chassis, with lightweight steel trellis frame in the proven KTM
design, turns it into a real surfer through the bends. Masses
grouped close to the centre of gravity maximize manoeuvrability and
precision - and prepare the 250 DUKE perfectly for the rush hour
slalom.

Telescopic fork
The KTM 250 DUKE's high-quality upside-down fork from WP Suspension
has the same 43 mm diameter as the RC8 R - in other words: real
racing equipment that guarantees highest levels of stability and
precision.

Swingarm
The 250 DUKE's lightweight, high-quality, pin-jointed, die-cast
swingarm is designed and produced according to the same principle as
the 690 DUKE. The light alloy swingarm with directly linked WP shock
absorber excels with extreme torsional stiffness and outstanding
tracking stability.

Ergonomics
The KTM 250 DUKE provides plenty of space and freedom of movement.
The gathered sitting position supports relaxed touring, alone or
two-up, as well as committed cornering. Unsurpassed operability and
large contact surfaces ensure optimum control and maximum feedback,
with the upright, relaxed sitting position providing a perfect
overview everytime.

Instruments
The 250 DUKE has everything that distinguishes a genuine KTM from
the high-quality chassis components to the multi-function cockpit,
which keeps you up to date with fuel consumption and remaining
range. The extensive KTM PowerParts range gives you the option of
adding your own individual style.
