SIX DAYS, SIX WINS

KTM and the International Six Day Enduro are undoubtedly some of the biggest names in offroad racing. We’d like to introduce you to the 250 EXC TPI SIX DAYS. Built to perform under the toughest conditions and boasting top-of-the-line components and ground-breaking 2-stroke fuel injection, the 2019 250 EXC TPI is a force to be reckoned with. Also for 2018, Chile will play host to the ISDE in Viña del Mar, and to honor this, the entire SIX DAY line-up receives a lick of blue, white and red highlight colors.

Motor og eksos

Motor og Eksos

When it comes to 250 cc 2-stoke machines, the motor in the 250 EXC TPI is the most powerful and most competitive in its class. The patented EFI system with two injectors mounted on the transfer ports of the cylinder makes for smoother power delivery, which translates to an easier ride. This also helps with dramatically reducing fuel consumption.
The 250 cc powerhouse also features a shaft arrangement that improves its mass centralization, a well-protected E-starter, a balancer shaft for low engine vibrations, a 6-speed transmission and a hydraulically operated DDS clutch.

TRANSMISSION

This 6-speed Enduro transmission features an Enduro-specific wide-ratio specification and provides precise and easy shifting. Keeping safety in mind, an advanced ´No Dirt´ gear shift lever design prevents muck from blocking the joint. Because even dirt lovers hate mud when it’s in the wrong places.

THROTTLE BODY

The TPI engine is fitted with a 39mm throttle body made by Dell`Orto. The airflow is regulated by a butterfly connected with a twin-cable throttle cam, which is operated by the handlebar throttle assembly. A throttle position sensor provides airflow data to the control unit, while a bypass screw allows the regulation of the idle […]

OIL PUMP

Pre-mixing 2-stroke fuel is a thing of the past for KTM EXC TPI owners. An electronic oil pump feeds oil from the oil tank via the throttle body into the engine intake, and ensures a perfect fuel-oil mix in all conditions and engine speeds. The system, which reduces up to 50% of the smoke from […]

ENGINE MANAGEMENT SYSTEM

The engine management system (EMS) of the TPI models features 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 […]

CYLINDER

The KTM 250 EXC TPI cylinder has a bore of 66.4mm and is fitted with the sophisticated power valve providing smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes, which hold the fuel injectors supplying fuel into the rear transfer ports. Thus the loss of unburnt fuel is reduced […]

CRANKCASES AND ENGINE COVERS

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. Which is nice if you care about sweet handling. In addition, it allows the implementation of a balancer shaft. So your ride will be as relaxed as it is rapid. […]

COOLING

KTM’s proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminum radiators made by WP. The additional KTM PowerParts radiator fan that riders can add to this fuel injected 2-stroke is now regulated by the control unit, no thermo switch is required anymore. Thanks to flow optimized internal […]

CLUTCH

The KTM 250 EXC TPI employs the KTM-developed DDS clutch (damped diaphragm steel) with a wear-free steel basket, extremely heat resistant clutch plates and nitrated steel liners. This clever design employs a diaphragm spring instead of the usual coil springs, making for considerably easier clutch action. A diaphragm spring also leaves sufficient space for a […]

BALANCER SHAFT

Say goodbye to numb feet and hands. This engine design allows the implementation of a lateral balancer shaft in order to keep the vibrations to a minimum. You know what that means: more comfort, less fatigue, bigger smiles.

Chassi

Chassi

A chrome-molybdenum steel tubing frame along with a lightweight subframe provides high torsional rigidity for best handling. The TPIs also feature a frame design that doubles as an oil reserve, routing 2-stroke engine oil from an added filler cap assembly, located between the fuel tank and the steering head, via a hose inside the upper frame tube to the oil tank.

WHEELS

The EXC wheels feature lightweight, CNC machined hubs and high-end Giant rims guaranteeing maximum stability at minimum weight. The wheels are fitted with MAXXIS tires – perfect for surefooted performance off-road and stability on-road.

TRIPLE CLAMP

All Six Days 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.

SWINGARM

The cast aluminum design offers low weight and a perfect flex behavior. The single-component casting process eliminates any inconsistencies and inherent weak points created by welding. It’s better looking too.

REAR SUSPENSION

The PDS is kind of a KTM trademark where the shock absorber is directly connected to the upper side of the swingarm. This setup boasts the best possible mounting geometry and provides amazingly progressive damping. The shock absorber is mounted close to the centerline, which means nearly symmetrical loads for the swingarm and frame and […]

FUEL TANK

This is a lightweight polyethylene tank with a capacity of 9.25 liters. The EXC TPI models incorporate an integrated fuel pump system and an additional fuel level sensor so you’ll always know when you’re running low on gas.

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 […]

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 […]

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.

AIRBOX

The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow. The large Twin Air air filter is mounted on a stiff cage, which at the same time holds the system in place. This design is so simple, you could still pop a fresh one in with a […]

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.

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 double-cable aluminum body and straightforward free-play adjustment. A volcanized grip sits on the right, while on the left […]

FOOTPEGS

Sophisticated ´No Dirt´ footpegs prevent smudging up the pegs, even when digging in deep ruts. The pegs on the Enduro models are 6mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.

Bodywork og dekaler

Bodywork og dekaler

Flying the Chilean colors, the plastics on the 250 EXC TPI SIX DAYS share the same I-beam structure on its front and rear fenders as the rest of the multi-race winning enduro range. This guarantees maximum stability and low weight thanks to well thought-out construction and mounting points. A clever brake hose routing on the front number plate also aids in reducing wear and tear.

SIX DAYS EQUIPMENT
