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 […]

EXHAUST

This nickel-plated pipe is produced by WP Performance Systems. It is designed for an optimal power band and maximal performance of the engine. A modern 3D production process guarantees top precision and reliability of the pipe, so this screamer is as tough as it is strong.

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 AND PISTON

Inside the cylinder, with a bore of 78mm, thumps a reliable box-type piston made by CP. Its crown geometry is adapted perfectly to the high-compression combustion chamber (12.8:1), where its rigid structure and low weight maximize performance. Thanks to low oscillating masses, the engine revs freely with plenty of power.

CYLINDER

The KTM 300 EXC TPI cylinder has a bore of 72mm and is fitted with the sophisticated power valve, which provides really smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes that hold the fuel injectors supplying fuel into the rear transfer ports. The downstream injection guarantees excellent atomization […]

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 300 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

When it comes to 2-stroke weaponry, keeping weight down is key. It should come as no surprise then that the KTM 300 EXC TPI is one of the lightest, slimmest and most agile enduro machines around.

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

Fitted with forged triple clamps with 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 EXC TPI 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

These high-tech Brembo babies are combined with lightweight Wave brake discs. You couldn’t brake any harder, better, faster or stronger.

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 […]

Ergonomi og komfort

Ergonomi og komfort

Designed for complete harmony between rider and bike, KTM has exploited the knowledge from decades of race success to create perfect ergonomics on the 300 EXC TPI. Maximum rider comfort and movement in all conditions is guaranteed.

HANDLEBAR

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
