Take the unrelenting ferocity of an SX bike, add a few extra horsepower and torque, a longer-range fuel tank and an 18″ rear wheel to accommodate more rubber, and you’re well-armed to dominate the dirt. In a nutshell, the KTM 300 XC TPI is arguably the most accomplished cross-country racer available.
The 300 cc 2-stroke engine is known and respected for offering the most powerful 2-stroke performance in its segment. Thanks to state-of-the-art engineering, innovative 2-stroke design and revolutionary TPI fuel injection technology, the powerplant is more refined than ever before. The compact and lightweight 2-stroke is a great choice for all Enduro riders searching for easy-to-ride Enduro performance with the power and torque to conquer the most extreme climbs.
The KTM 300 XC TPI cylinder has a bore of 72mm and is fitted with a state-of-the-art 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 of the fuel with the upstreaming air. Thus the loss of unburnt fuel is minimal for fewer emissions, a more efficient combustion and reduced fuel consumption. A little tube in the back of the cylinder is connected with an intake pressure sensor, which supplies pressure data to the control unit.
These die-cast crankcases allow the implementation of a balancer shaft. So your ride will be as relaxed as it is rapid. Plus, your new favorite engine will keep looking as fresh as the day you bought it: its engine covers feature a smart surface structure in order to reduce the wear caused by the rider’s boots.
The robust 6-speed transmission made by PANKL Racing Systems features an Enduro-specific wide-ratio specification and provides precise and easy shifting. An advanced ´No Dirt´ gear shift lever design prevents mud and dirt from blocking the joint. Because even dirt lovers hate mud when it’s in the wrong places.
The engine management system (EMS) of the TPI models features a control unit located below the seat. The ECU defines the ignition timing while the amount of fuel to inject is based on several sensor readings such as intake air pressure, throttle position and water temperature plus a new additional ambient air pressure sensor. Thanks to altitude and temperature compensation the rider does not need to worry about fiddling around with the jetting anymore. Should the rider decide to mount a radiator fan from the KTM PowerParts program, it will be controlled directly by the EMS without needing to add an additional thermal switch.
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, more racing.
The KTM 300 XC TPI employs the KTM-developed DDS clutch (damped diaphragm steel) with a robust steel basket, extremely heat resistant clutch plates and new, nitrated steel liners reducing the wear. 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 damping system to be integrated into the clutch hub. The goal is traction, but durability is as well. Light operation and telepathic amounts of control are standard with this hydraulic Brembo actuated clutch.
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 300 XC TPI features radiators which are mounted close to the center of gravity and match the design of the shrouds perfectly, in order to achieve perfect ergonomics. The additional KTM PowerParts radiator fan is regulated by the EMS control unit for easy installation. Thanks to flow optimized internal circulation and CFD-calculated ventilation, the system is superbly efficient. In addition the radiator protectors improve heat dissipation. Especially in the mud. They are also integrated into the front part of the shrouds to protect the radiators in a crash.
When it comes to power delivery and performance, the exhaust plays a key role and packs a punch that is hard to beat. The 250 cc and 300 cc models feature HD exhaust pipes (heavy-duty) made by using an innovative 3D stamping process which produces a ribbed surface finish. This makes the pipe much stronger, with better resistance against rocks, while also helping to reduce noise drastically. The silencer features a compact shape and end cap with internal designs individually developed for each model, while it is mounted using an aluminum mounting bracket. In addition, the exhaust’s shape provides slim ergonomics and more ground clearance, while a perforated inner silencer tube works with lighter damping material for efficient and durable noise reduction.
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 low vibration level. In addition, it is easy to maintain and to work on and supplies ample space for the tank and other components. On the XC 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 aluminum, which tiptoes the scales at less than 2 pounds.
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.
The KTM 300 XC TPI is fitted with lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight aluminum nipples providing maximum stability at minimum weight. The latest Dunlop Geomax AT81 tires guarantee perfect traction and outstanding performance.
All XC-W models are fitted with the latest 48 mm diameter WP XPLOR upside-down forks, featuring a split fork design developed by WP and 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. So the fork can easily be adjusted for compression and rebound with the twist of a dial on top of the fork tubes (30 clicks each). Although already distinguished for outstanding response and damping characteristics, the fork features a calibrated mid-valve piston for consistent damping. The settings keep the front end higher in the stroke, providing impressive reserves against bottoming out.
The WP XPLOR shock absorber is the key element on the proven PDS rear suspension design (progressive damping system), where the shock is directly linked to the swingarm without an additional linkage system. This keeps weight lower and reduces the chances of hooking on rocks. The progressive damping is achieved by a second piston, which works together with a closed cup towards the end of the stroke. This design contributes to an optimal progression behavior of the damping supported by a progressive shock spring. It is fully adjustable, including high and low-speed compression, so you can set the shock up to suit any track, trail and rider preferences.
Top quality, CNC machined triple clamps have been a KTM trademark for years to ensure precise handling. The rubber damped handlebar fixation allows for two positions and an hourmeter is fitted in order to let the rider know it’s time for a service.
These high-tech Brembo babies are combined with lightweight wave discs. You couldn’t brake any harder, better, faster or stronger.
This is a lightweight polyethylene tank with a capacity of 2.4 gallons. Manufactured using see‐through plastic, you will always be able to see how much fuel remains at a glance. Additionally, the XC 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.
The air filter box design offers maximum protection of the air filter against soiling, while ensuring maximum airflow, and together with the intake snorkels, results in optimal power and throttle response. 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 face full of mud. Without tools. In seconds.
The XC range features state-of-the-art seat technology with a newly shaped surface that provides improved ergonomics and much better seat comfort thanks to higher foam padding. The seat is conveniently fixed to the bike using one long, lateral screw, making it safe and easy to handle.
KTM engineers sure know how to handle handlebars. This tapered unit, made of high-strength aluminum by NEKEN, features a throttle assembly which has a twin-cable for TPI models just like their 4-stroke brothers with a double-cable aluminum body and straightforward free-play adjustment. A vulcanized 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.
Sophisticated ´No Dirt´ footpegs prevent jamming up the pegs, even when digging in deep ruts. The pegs on the Cross Country models are 6mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.
