The 2023 KTM 300 EXC SIX DAYS wears its IDSE badges proudly. Not only has this machine won more extreme enduro championships than most, but it also takes the accolade as one of the most complete enduro weapons on the market. Featuring a fuel-injected 2-stroke engine, top-end WP suspension, and unique KTM SIX DAYS finishes, the KTM 300 EXC SIX DAYS is primed and ready to lift its next trophy.
A legend in its own right, the KTM 300 cc 2-stroke engine has long been a favorite when it comes to enduro weaponry. This is largely down to its exceptional power, low-down torque and overall lightweight. Thanks to state-of-the-art engineering, innovative 2-stroke design, and revolutionary TPI fuel injection technology, this powerplant has become a truly refined unit.
The cylinder on the KTM 300 EXC TPI SIX DAYS has a bore of 72 mm and is fitted with a sophisticated power valve, providing ultra-smooth and controllable power characteristics. Being fuel-injected, the cylinder features two lateral domes which hold the fuel injectors, supplying 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 fewer emissions, more efficient combustion, and reduced fuel consumption. The cylinder also features 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.
CRANKCASES AND ENGINE COVERS
These compact engine cases are manufactured using a high-pressure die-cast production process which helps with weight reduction but maintains strength and durability. This design also allows for optimal shaft arrangements close to the center of gravity, resulting in ideal mass centralization and ride-ability.
The KTM 300 EXC TPI SIX DAYS makes use of 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 KTM 300 EXC TPI 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.
ENGINE MANAGEMENT SYSTEM
The engine management system (EMS) of all 2-stroke EXC 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, water temperature , and ambient air pressure. Thanks to altitude and temperature compensation, re-jetting is a thing of the past, meaning more time twisting throttles and less time turning screws. Should the rider decide to mount a radiator fan from the KTM PowerParts, it will be controlled directly by the EMS without needing to add an additional thermal switch.
The KTM 300 EXC TPI engine design allows for the implementation of a lateral balancer shaft in order to keep engine vibrations to a minimum. This means riders can focus on the obstacles ahead of them, with out distraction. After all, more comfort equals less fatigue.
The KTM 300 EXC TPI SIX DAYS 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 enduro range is fitted with a frame-mounted oil tank featuring flexible mountings, which greatly improves durability and reliability. In addition, a mesh filter preventss dirt from getting into the oil pumpand into the fuel. This works in conjunction with the oil pump, that 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. With an average fuel-to-oil ratio of 1:80, an oil capacity of about 0.7 liters is sufficient for at least five tanks of fuel.
The KTM 300 EXC TPI engine is fitted with a 39 mm throttle body made by Dell`Orto. These regulate the airflow via a butterfly connected with a twin-cable throttle cam, which is operated by the handlebar throttle assembly, supported by a throttle position sensor that provides airflow data to the control unit. What all this means is, riders can precisely set the idle speed via the bypass screw, as well as easier cold starts.
In order to accommodate the power requirements of the engine management system, all KTM XC-W TPI models are fitted with a powerful 196 W alternator and voltage regulator to ensure all systems are always powered up.
Keeping the engine cool when the going gets tough comes courtesy of a pair of radiators, mounted close to the center of gravity. These make use of CFD technology (Computational Fluid Dynamics) and clever coolant circuit routing, achieving optimum engine temperature for the highest performance, in all conditions. Above all, the delta distributor, integrated into the frame triangle, features a large center tube for highly efficient coolant flow. The radiators also benefit from plastic protection fins 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.
There's more to it than 'braaaap!'. The exhaust plays a key role in packing that signature 2-stroke punch. All KTM 300 EXC TPI models feature heavy-duty exhaust headers made using an innovative 3D stamping process that produces a ribbed surface finish. This makes the pipe much stronger, with better impact resistance, while also helping to reduce noise. The silencer features a compact shape and end cap with internal designs individually developed for each model and mounted using an aluminum bracket for strength. In addition, the exhaust's overall shape provides a slim profile resulting in improved ground clearance, while a perforated inner silencer tube uses lightweight damping material for efficient and durable noise reduction.
All KTM SIX DAY models feature high-tech, lightweight Chromoly steel frames with race-derived geometry, optimal stiffness, and unparalleled feedback for the rider. This translates into a playful handling character, with remarkable stability at speed. The subframe is made of extra-light and ultra-stable aluminum profiles, weighing less than 900 grams providing rear fender stability and durability in the event of a loop out.
The KTM 300 EXC TPI SIX DAYS features a one-piece aluminum swingarm, which is manufactured using a gravity die-cast production process. This results in exeptional strength at the lowest possible weight and the perfect flex behavior.
KTM uses lightweight, CNC-machined hubs and high-end GIANT rims on all KTM SIX DAYS models. These guarantee maximum stability and the bare minimum weight, while aluminum spoke nipples feature an innovative design, which reduces the need to continuously tighten the spokes. They also look the part with unique SIX DAYS branding.
Putting the power to the ground is a set of aptly named, Metzeler 6 DAYS EXTREME Extreme tires. These provide excellent grip across any terrain, as well as self-cleaning knobblies to ensure all the traction, all of the time.
New slots in the outer fork tube mean the 48 mm diameter WP XPLOR upside-down forks feed more oil to the bushes and reduce friction and heat build-up. The fork springs have also been updated with a new polished surface finish to improve consistency and new valve dedign increases rebound damping performance. The forks retain their adjustability, with compression damping on the left and rebound on the right.
The race-proven and fully adjustable WP XPLOR shock absorber has received a re-tune, with factory settings making it firmer, and new conical bushing between the pistons to improve bottoming reserves. This has resulted in reduced fade and improved wear, taking the PDS rear suspension design even further in its quest for podiums.
All SIX DAYS models are fitted with high-end, orange anodized CNC machined triple clamps. These have an offset of 22 mm, ensuring a solid grip of the fork, providing precise feedback through the handlebar. Speaking of which, the bars are adjustable forwards and backward over 4 positions allowing you to find your ideal 'attack' position.
High-tech Brembo brake calipers and lightweight wave brake discs ensure you stop when you need to. Thanks in part to a floating front brake disc and solid rear disc, brake fade is minimized and allows for harder braking, more of the time. For additional strength and reliability, the rear brake pedal is secured with a safety wire.
All KTM enduro models are fitted with lightweight polyethylene tank, with a ¼‐turn bayonet-style filler cap makes for quick and easy operation. The integrated fuel pump ensures a direct feed to the injectors, while a 90° connector provides protection against damage. The tank is also manufactured using see‐through plastic, riders are able to gauge fuel levels at a glance and on the go.
The easy-access airbox on the KTM 300 EXC TPI SIX DAYS ensures optimal flow dynamics, thanks to specially designed intake snorkels. This means air is force-fed into the motor, resulting in the perfect balance of power and throttle response. Keeping the air clean, is a large Twin-Air air filter fitted to a rigid cage for ideal placement at all times.
All KTM SIX DAYS models are equipped with adjustable, high-strength aluminum tapered handlebars, that can be mounted in four different positions. Standard with ODI vulcanized grip on the right side and a comfortable ODI lock-on grip on the left, your only worry is hanging on, and letting rip.
It goes without saying that six days spent in the saddle require a certain level of comfort. For that reason, the KTM 300 EXC TPI SIX DAYS features a softer, grippier seat, finished in a striking blue and red color combination.
Self-cleaning footpegs prevent mud from clogging up the pegs, even when dragging them through deep ruts. This means your boots maintain their grip, and you maintain your focus on the trail.
SIX DAYS EQUIPMENT
