KTM 250 EXC TPI Six Days 2018:Six Days, six wins
Beskrivelse
KTM has ruled off-road for decades. The special edition Six Days models celebrate this success with special performance upgrades and top-of-the-line components. In 2017 the ISDE (International Six Days of Enduro) will be held in Brive-la-Gaillarde, France and the KTM model line-up has been suitably equipped to handle anything the muddy and rocky terrain can throw at it.
BODYWORK
KTM R&D, KISKA Design and the factory racers had their say
in shaping the plastics with one goal: complete harmony between
rider and bike. Perfect ergonomics and contact points provide
maximum comfort in movement on the EXC. The I-beam structures
of the front and rear fenders guarantee maximum stability
and a low weight thanks to well thought-out construction
and mounting. They also stay cleaner for longer. Clever brake hose
routing on the front number plate prevents wear and tear.
HANDLEBAR
KTM engineers sure know how to handle handlebars. This
tapered one, made of high-strength aluminum by NEKEN,
features a throttle assembly, which now has a twin-cable for
EXC TPI models just like their 4-stroke brothers, with a new
double-cable aluminum body and straightforward free-play
adjustment. A volcanized grip sits on the right, while on the left
side of the bar a comfortable ODI lock-on grip is mounted, which
does not require any wire or glue to be fixed. A map select
switch at the handlebar allows for the selection of an alternative
map, so you can be fully prepared for any condition.
SEAT
Tailored to meet the needs of the world’s fastest backsides, this
durable seat offers great comfort, helping you master the most
challenging terrain all day long.
FRONT SUSPENSION
The WP Xplor 48 upside-down fork is a split fork developed by WP
in close collaboration with KTM. It is fitted with a spring on both
sides but features separated functions for each fork leg:
compression damping is fitted on the left side, while rebound is
on the right. The forks can easily be adjusted for compression
and rebound with the twist of a dial on the top of the forks.
New outer fork tubes and a reworked setting make for more
sensitivity, improved damping behavior and a reduced weight. In
addition, a sealed hydro-stop guarantees excellent resistance
to bottoming-out. Due to high-quality materials and a
state-of-the-art production process, the new WP Xplor 48 fork – with
approx. 300mm of travel – has outstanding response and
damping characteristics. A comfortable preload adjuster is
Sixdays standard and allows for a simple spring preload setting in
three steps without tools (standard, +3mm, +6mm).
ENGINE MANAGEMENT SYSTEM
The engine management system (EMS) of the TPI models features
a new throttle body made by Dell`Orto with a diameter
of 39 mm and a control unit located below the seat. The control
unit determines the ignition timing and the amount of fuel to inject is based
on several sensor readings such as intake and ambient air
pressure, throttle position, oil and water temperature. Thanks
to altitude and temperature compensation the rider does not need
to worry about fiddling around with the jetting anymore.
FRAME
The high-tech, lightweight chrome-moly steel frame has a knack for
easy handling, outlandish rideability, precise cornering and
excellent stability. You can also count on high torsional rigidity
and low longitudinal stiffness. This results in better absorption
of the energy created from the front and rear suspension sucking
up jumps and bumps. In short: more comfort and less rider
fatigue. Laterally attached, lightweight engine head stays (the connection
between cylinder head and frame) contribute to a reduced vibration
level. Two threaded inserts in the lower cradle tubes allow
for safe fixation of an optional skid plate. The engineers could
pull off all that, while making their frame a big fat kilogram lighter
than that of the lightest competitor on the market. In addition,
it is easier to maintain, easier to work on and supplies more
space for the tank and other components. On the EXC TPI models
the upper frame tube features a slot where the oil filler cap
is mounted, which feeds the oil tank via a hose inside the frame tube.
The bike also features an extra-light subframe made of stable
aluminum profiles, which tiptoes the scales at less than 900g.
BRAKES
You can’t brake any harder, better, faster or stronger. High-tech Brembo
calipers are combined with lightweight Wave brake discs. The steel-flex
front brake hose has efficient protection and there’s an integrated
channel for the speedometer cable. First you outrun them,
then you outbrake them.
TRIPLE CLAMPS
All Sixdays models are fitted with high-end CNC machined triple
clamps anodized in orange and an offset of 22mm, ensuring
a solid grip of the fork and precise handling. The handlebar is
adjustable forwards and backwards over 4
positions, so the bike will fit you like your favorite gloves.
