The KTM 300 EXC has been at the forefront of the insane pace of development within Extreme Enduro. This nimble, lightweight all-terrain master fears no obstacle, making it the ultimate machine for taking on the renowned Iron Giant. The special ERZBERGRODEO limited edition is packed with KTM PowerParts and a unique graphics kit to commemorate this special event. With everything you need to conquer the world’s most extreme enduro race, this unique machine is ready to take you forward in your journey to more extreme enduro.
The 300 cc 2-stroke engine has plenty of power and torque, but remains light enough for riders to muscle their way through the toughest obstacles. 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 offroad riders who want usable enduro performance that is ready to conquer in the most extreme terrain. With Euro IV homologation, it’s not only considerately green, but leaves the competition green with envy too.
The cylinder on the KTM 300 EXC TPI ERZBERGRODEO has a bore of 72 mm and is fitted with a sophisticated power valve, which provides really smooth and controllable power characteristics. For the EFI application the cylinder features two lateral domes which hold the fuel injectors that supply fuel to 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 less 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. The cylinders feature a state-of-the-art power valve unit with a sophisticated mechanism for the lateral support exhaust ports. The exhaust port layout increases engine performance, while the upper contour of the exhaust port has been machined to ensure more accurate port timing. Last but not least the models allow the use of a more widely available type of traditional spark plug.
The compact engine cases are manufactured using a high pressure die-cast production process which helps with weight reduction, while retaining strength and durability. The design allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass centralization and easier ride-ability. This model comes with a special KTM PowerParts oil plug and together with the smart surface structure on the engine covers, it will continue to look as fresh as the day you bought it.
The KTM 300 EXC TPI is fitted with a robust 6-speed transmission made by PANKL RACING SYSTEMS. The gears are made of a strong, forged raw material, ensuring the highest durability and reliability level. Another highlight of the 300 EXC TPI ERZBERGRODEO transmission is the no-dirt gear shifter. Similar to the footpeg design, it prevents the build-up of dirt and ensures the next gear is always available, no matter what the conditions.
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. The ERZBERGRODEO edition comes with a map select switch, which allows the rider to select between a standard and advanced map while on the fly, for the optimal power delivery in every condition.
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.
The KTM 300 EXC TPI ERZBERGRODEO 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 damping system to be integrated into the clutch hub. The goal is traction, but without compromising durability. Light operation and a ‘telepathic’ level of control come standard with this hydraulic Brembo actuated clutch. Additionally, this model comes with clutch slave cylinder protection.
Pre-mixing 2-stroke fuel is a thing of the past for KTM EXC TPI owners. The 2-stroke range is fitted with an oil tank featuring flexible mountings, which greatly improve durability and reliability. In addition, a mesh filter helps prevent dirt getting into the oil pump. Mounted below the oil tank, the oil pump delivers the lubricant directly to the throttle body, where it is mixed with the incoming air to lubricate the piston and crankshaft. Using engine speed and throttle position sensor data, the engine management’s precise electronic control of the oil pump ensures that the ideal amount of oil for any given conditions is used. 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 transfer the oil to the storage container. With an average fuel-to-oil ratio of 1:80, the oil capacity of about 0.7 liters is sufficient for at least five tanks of fuel.
The TPI engine is fitted with a 39 mm 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. The idle system allows the idle speed to be set more precisely via the bypass screw. Also, the cold start system provides a better supply of extra air when opening a bypass. Oil supplied by the electronically controlled oil pump via an oil intake tube is mixed with the incoming air to lubricate the moving engine parts.
To accommodate the power requirements of the engine management system, the TPI models are fitted with a powerful 196 W alternator and a voltage regulator. The same as can be found on the EXC-F 4-stroke models.
Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 300 EXC TPI ERZBERGRODEO 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. By using CFD technology (computational fluid dynamics) together with a clever coolant circuit routing, the innovative system ensures the optimum engine temperature for the highest performance, no matter what the conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube, making the coolant flow from the cylinder head to the radiators highly efficient. This special model comes with a radiator fan. The radiators also benefit from special protectors that serve as protection from flying rocks and debris, as well as a brace that disperses energy around the radiators in the event of an impact.
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.
All KTM EXC models feature a high-tech, lightweight chromoly steel frame. This includes hydro-formed elements produced by state-of-the-art robot welding. With its race-proven geometries and optimal stiffness, the frame provides great feedback for the rider, playful handling and remarkable stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature lateral frame guards with a structured surface, improving grip, while also serving as a heat protector against the muffler on the right side. The subframe is made of extra-light and stable aluminum profiles, weighing less than 900 gr, providing great rear fender stability.
The KTM 300 EXC TPI ERZBERGRODEO’s one-piece aluminum swingarm is manufactured using a gravity die-cast production process, offering exceptional strength at the lowest possible weight. The single-component casting process offers low weight, perfect flex behavior and also allows for a large number of geometry solutions.
Every extreme enduro rider is looking for reliable forward momentum and the KTM 300 EXC TPI ERZBERGRODEO edition guarantees this with the highest quality CNC machined factory wheels with anodized orange hubs. To ensure your progress is never haulted, even in the toughest, most slippery conditions, it comes standard with the soft version of the METZELER EXTREME rear tire.
The KTM 300 EXC TPI ERZBERGRODEO is fitted with the latest 48 mm diameter WP XPLOR upside-down forks, featuring a split fork design developed by WP and KTM. While each side is fitted with springs, they have separate damping functions. Compression damping is on the left and the rebound on the right. Both can be easily adjusted via the dials on top of both fork tubes with 30 clicks each. Although already distinguished for outstanding response and damping characteristics, the fork features a calibrated mid-valve piston for consistent damping. The new settings keep the front end higher in the stroke, providing impressive reserves against bottoming out. The ERZBERGRODEO edition comes with special CNC machined triple clamps that combine perfectly with the WP XPLOR fork.
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. Optimal enduro-specific damping progression is achieved by using a second damping piston in combination with a closed cup towards the end of the stroke, and supported by a progressive shock spring. The settings on the XPLOR PDS shock provide impressive damping characteristics and match the frames and front-end set-up perfectly. 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.
These high-tech Brembo babies are combined with lightweight wave brake discs, including a solid disk on the rear. You couldn’t brake any harder or with better feel on an offroad motorcycle. The ERZBERGRODEO edition provides extra reliability with a front and rear brake disc guard, as well as a rear brake safety wire.
All models in the EXC range are fitted with lightweight polyethylene tanks improving the ergonomics. The ¼‐turn bayonet filler cap makes for quick and easy closure. Manufactured using see‐through plastic, you will always be able to see how much fuel remains at a glance. It is fitted with an integrated fuel pump system and a fuel level sensor. Additionally, the fuel line features a 90° connector to the tank for better protection against damage.
The airbox on the KTM 300 EXC TPI ERZBERGRODEO ensures optimal flow dynamics, and together with the intake snorkels, results in optimal power and throttle response. Despite the obvious performance enhancements, the design also offers maximum protection against soiling of the air filter. The large Twin-Air air filter is mounted on a cleverly designed stiff cage that minimizes incorrect installation. As found on previous models, filter maintenance is quick and easy and does not require tools – a standard, original feature from KTM.
All KTM EXC models are equipped with the same high-strength aluminum tapered handlebar, made by NEKEN. The handlebar allows for four different positions. The handlebars come standard with an ODI vulcanized grip on the right side and a comfortable ODI lock-on grip, which does not require any wire or glue, on the left. Additionally, the KTM 300 EXC TPI ERZBERGRODEO is equipped with a handlebar map select switch, which allows to select between a standard and advanced power curve.
Sophisticated ´No-Dirt´ footpegs prevent clogging 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.
