On the 4-stroke side, KTM offers the well-known range from the
super easy to ride 250 EXC-F to the all-rounder 350 EXC-F to the
big thumper 500 EXC-F.
CHASSIS GENERAL
FRAME
The frames of all KTM off-road models are manufactured from
lightweight sections of top-quality chrome-molybdenum steel tubing
of various cross-sections. This type of frame design provides high
torsional rigidity for best handling and rideability, while a
certain longitudinal flexibility can absorb the wheel impact
energy, supporting the suspension for reduced rider fatigue. At the
same time, the frame triangle serves to deliver the coolant from
the cylinder head directly to the radiators. In the TPI models, the
frame design also serves to route engine oil from a filler cap
assembly, located between the fuel tank and the steering head, via
a hose inside the upper frame tube to the oil tank.
SWINGARM
This swing arm design allows for an optimal mounting position of
the PDS (progressive damping system) rear shock ensuring a high
progression rate. The single-component casting process eliminates
any inconsistencies and weak points that would be inherent in a
welded swing arm.
FORKS
All EXC models are fitted with the latest WP XPlor 48 upside-down
forks, a split fork design developed by WP Performance Systems and
KTM. It is fitted with springs on both sides but separate damping
functions. Compression damping is on the left and the rebound on
the right hand side without influencing each other. Therefore
damping can easily be adjusted via the dials on top of both fork
tubes with a range of 30 clicks each.
Already distinguished by outstanding response and damping
characteristics the fork features an updated slightly stiffer
setting for model year 2019 keeping the front end higher and
providing increased reserves against bottoming out.
NEW:
- Updated, slightly stiffer fork setting à improved feedback and
more bottoming resistance
SHOCK ABSORBER
Fitted to all EXC-F and XC-W models, the WP XPlor PDS shock
absorber is the key element of the proven and successful PDS rear
suspension design (Progressive Damping System) where the shock is
directly linked to the swing arm without an additional linkage
system. Optimal damping progression for offroad duty is achieved by
a second damping piston in combination with a closed cup towards
the end of the stroke, and supported by a progressive shock spring.
This means the XPlor PDS shock provides excellent damping
performance and a high resistance against bottoming out. An updated
main piston and new settings provide improved damping
characteristics and match perfectly the reworked front end set-up.
Fully adjustable including high- and low speed compression you can
set the shock to any track and riders preferences.
NEW:
- WP monoshock with reworked main piston and settings for all
models à More comfort and increased bottoming control
TRIPLE CLAMPS
The EXC-F and XC-W models are fitted with highly rigid, forged
triple clamps with an offset of 22 mm, providing a solid grip on
the forks for precise handling. They allow forwards and backwards
adjustment of the handlebars in four different positions for
optimum rider ergonomics.
WHEELS & BRAKES
The KTM wheels use lightweight, CNC machined hubs and high-end,
black GIANT rims to combine maximum stability and ruggedness with
minimum weight.
BRAKES
BREMBO brakes have been the standard equipment on KTM's off-road
range forever, and combined with the lightweight Wave discs with
diameters of 260 mm front and 220 mm on the rear wheel, they remain
the class-leading system when it comes to that crucial combination
of stopping power and a transparent brake feel.
COOLING SYSTEM
KTM's proven cooling system routes the coolant from the cylinder
head through the frame triangle directly to aluminum radiators made
by WP Performance Systems. Due to flow calculated internal
circulation and CFD optimized air ventilation, the system is
superbly efficient. In addition, well thought-out radiator guards
guarantee excellent protection against mud while at the same time
serve as efficient crash protectors. All EXC-F's are fitted with a
radiator fan as a standard feature.
EXHAUST SYSTEM
Noise limits have become challenging for every manufacturer to
meet, prompting KTM to put a lot of effort into the development of
their exhaust systems. All models are fitted with state-of-the-art
exhaust systems which guarantee maximum performance, low weight and
conformity with the mandated noise limits.
HANDLEBAR
The tapered Neken handlebar is made of high-strength aluminum and
can be is mounted in 4 different positions in order to suit
different rider sizes. ODI lock-on grips make grip changes easy and
do not require any wire or glue to be secured.
FOOTPEGS
KTM's advanced ´No Dirt´ foot pegs prevent clogging up the pegs,
even when digging into the side walls of deep ruts. With the
specifically designed pegs for the EXC models the rider stands six
millimeters higher than the ones used on SX versions for increased
ground clearance. They are easy to swap though if so desired in
case a rider prefers a lower position.
SEAT
Ergonomically perfect, the seat was shaped specifically for offroad
requirements and features a new seat cover with foam padded stripes
providing improved comfort and grip.
NEW:
- New seat cover for improved comfort and grip
FUEL TANK
The lightweight, polyethylene tank on 2 strokes and polyamide tank
on 4 strokes allows gauging the remaining fuel with just a quick
glance, thanks to its see-through plastic. The filler cap features
a ¼-turn bayonet mechanism with an orange quick-release button for
extra fast refueling. All fuel-injected models are fitted with an
integrated fuel pump system and an additional fuel level sensor,
which indicates low fuel level via a warning light in the
speedometer.
AIRBOX
The air box design combines maximum protection of the air filter
against soiling with maximum airflow and low intake noise. The
large Twin Air filter is mounted in a stiff cage, which at the same
time holds the system in place, allowing extremely quick filter
changes in the field without tools while minimizing the risk of
incorrect filter installation.
E-STARTER & BATTERY
All models are equipped with proven electric starter systems - a
super beneficial feature once the going gets tough. A new and more
capable, super lightweight 2 Ah Lithium-Ion starter battery
provides even better starting of the engine especially at cold
weather conditions and contributes to the low vehicle weight.
NEW:
- Stronger and super lightweight Lithium-Ion battery for better
starting
BODYWORK & ERGONOMICS

between the KTM development department, Kiska Design and all KTM
factory riders, achieving complete harmony between rider and bike.
The results are well-balanced ergonomics and ideally shaped contact
points, maximum freedom of movement for the rider, a low seat
height and astonishing levels of comfort. Intelligent design is
also manifest in details like the smart solution that guides the
brake hose in the headlight mask, or the I-beam structures of the
front and rear fenders, which help to ensure maximum stability, low
weight and reduced dirt accumulation.

2019 KTM 300 XC-W TPI
The 300 EXC TPI with its state-of-the-art TPI fuel injection and
its super-agile chassis sets a clear benchmark. Thanks to its
unrivaled performance and rideability it is the first choice when
the going gets really difficult. There is no better power-to-weight
ratio on the market in a standard bike.
ENGINE
The 250cc and 300cc 2-stroke generations have been known and
respected for offering the most powerful 2-stroke performance in
its segment. For MY2018 though, KTM underscored its continuous
commitment to 2-stroke technology with its revolutionary TPI fuel
injection. In combination with its state-of-the-art engine design,
these power plants are even more refined than ever. The compact
2-strokes are a great choice for advanced off-road rider's
conscious of their purchasing and maintenance budget.
CYLINDER
The 250/300cc cylinders are fitted with the sophisticated TVC
exhaust control and have a bore diameter of 66.4 and 72.0 mm. For
the fuel injection, they feature two lateral domes holding the fuel
injectors that inject fuel into the rear transfer ports. This
downstream injection guarantees excellent atomization of the fuel
with the upstreaming air for a highly efficient combustion and
significantly reduced losses of unburned fuel. The engine
management system's intake pressure sensor is connected via a
small-diameter tube in the back of the cylinder.
THROTTLE BODY
The TPI engines are fitted with a 39 mm throttle body made by
Dell'Orto. Power is controlled by a throttle valve while intake air
data is provided to the engine management system by a throttle
position sensor. An adjusting screw allows the idle speed to be set
and a cold start device is provided, opening a bypass to supply
extra air. Oil supplied by the automatic oil pump via an oil
suction pipe is mixed with the incoming air to lubricate the moving
engine parts.
OIL PUMP
An oil pump mounted underneath the
oil tank delivers the lubricant to the throttle body, where minute
quantities are mixed with the incoming air in order to lubricate
the moving engine parts. Using engine speed and throttle position
sensor data, the engine management system's precise electronic
control of the oil pump ensures the perfect amount of oil for any
given conditions, loads and engine speeds is added.
The filler cap assembly for the oil tank is located between the
fuel tank and steering head, utilizing a hose in the upper frame
tube to conduct the oil to the storage container. Automatic,
electronically controlled oil injection reduces exhaust smoke by up
to 50% over conventional pre-mix lubrication, with an average
fuel-to-oil ratio of 1:80. This means the oil capacity of about
three quarters of a quart is sufficient for at least five tanks of
fuel.
BALANCER SHAFT
For optimal mass centralization, the lightweight, die-cast
crankcases hold the clutch shaft and the crankshaft
in a high position close to the center of gravity supporting the
handling of the bike. In addition, this design allows the
implementation of a lateral balancer shaft to minimize vibrations,
enhancing comfort and reducing rider fatigue during long and
demanding offroad events and rallies.
CLUTCH
The KTM XC-W TPI models employ the KTM-developed DDS clutch (damped
diaphragm steel) with a highly resilient steel basket and extremely
heat resistant clutch plates, a design distinguished by a
considerably easier clutch operation than with conventional coil
springs. The diaphragm spring also leaves sufficient space for a
damping system integrated into the clutch hub, which benefits both
traction and durability.
The hydraulic Brembo clutch mechanism is synonymous with a light
action and highly controlled clutch modulation.
ENGINE MANAGEMENT SYSTEM
The KTM 250 XC-W TPI and 300 XC-W TPI models feature the most
modern engine management system (EMS) of any 2-stroke off-road
motorcycle. The electronic control unit is located below the seat
utilizing various sensor data such as intake and ambient air
pressure, throttle valve position and water temperature, the
control unit optimizes ignition timing and the amount of fuel to
inject. Thanks to its automatic altitude and temperature
compensation, there is no need for the rider or mechanic to set up
the bike for the prevailing environmental conditions. An optional
map select switch allows the rider to select an alternate map,
providing a smoother power delivery. In
addition, for the 300 XC-W TPI the dealer can flash a RACE map
to be activated as the alternative
map.
GENERATOR
In order to accommodate the power requirements of the upgraded
engine management system, the TPI models are fitted with a powerful
generator, rated at 196 W, just like on the EXC-F 4-stroke models,
as well as the EXC-F voltage regulator.
TRANSMISSION
The rugged 6-speed transmission features widely spaced gear ratios
optimized for offroad duty. It provides precise and easy shifting.
The KTM 'No Dirt' gear shift lever design prevents dirt from
blocking the joint of the gear shift lever for safe and reliable
shifting in any conditions.
