250 EXC-F SIX DAYS 2021
KTM 250 EXC-F SIX DAYS 2021 for Sale at Ultimate KTM Gold Coast in Nerang, QLD | Specifications and Review Information
LIGHTWEIGHT TRAIL CONQUERER
No other brand stands up to the success of KTM when it comes to enduro, and this is clearly evident in the biggest competition on the calendar, the 'International Six Days Enduro' (ISDE). From its humble beginnings, the ISDE has turned into the team world championship of the Enduro scene. This Enduro marathon demands as much from the bikes as it does from the riders, and every year, more than half of them show up on Orange. The 2021 KTM SIX DAYS models pay the ultimate tribute to the event that was originally set to take place in Italy in 2020 and had to be rescheduled for 2021. No chain is stronger than its weakest link, so no compromise can be made for those intent on crossing the finish line. KTM, once again, rises to the challenge with the latest, limited Six Days edition of extra-tough machines. Easily identified by their special Six Days design, these bikes feature an extended list of top-of-the-line components, all specially designed and refined by KTM's own research and development department. These are the ultimate Enduro bikes for the exceptional event.
CYLINDER HEAD
The centerpiece of the compact DOHC engine is this cutting-edge cylinder head. It features light, dual overhead camshafts with friction-optimized cam followers boasting a hard DLC coating. Four lightweight titanium valves and high-flow ports maximize the flow rate for an optimal power band and outstanding performance across the seemingly endless rev range of 12,800rpm. Two lateral stays allow an efficient fixation of the engine to the frame and reduce vibration.
CRANKSHAFT
The KTM 250 EXC-F's crankshaft utilizes a short connecting rod, making for an overall compact and lightweight engine with a snappy power delivery. A plain big (bottom) end bearing with two force-fitted bearing shells runs directly on the crank pin. This design is a must for the extremely high engine speeds and the unrivaled power of this 250cc engine while also enhancing the engine's durability for long crankshaft service intervals.
CRANKCASES AND ENGINE COVERS
The design of the die-cast engine crankcases allows for a centralized shaft configuration, moving the crankshaft close to the bike's center of gravity. All hail mass-centralization! The engine covers feature an advanced surface structure to reduce the wear caused by the rider's boots.
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 and less rider fatigue. Laterally attached, lightweight engine head stays (the connection between cylinder head and frame) contribute to a reduced vibration level. Two threaded inserts in the lower cradle tubes allow for safe fixation of an optional skid plate. The engineers could pull off all that, while making their frame a big fat kilogram lighter than that of the lightest competitor on the market. In addition, it is easier to maintain, easier to work on and supplies more space for the tank and other components. The bike also features an extra-light subframe made of stable aluminum profiles, which tiptoes the scales at less than 900g.
COOLING
KTM's proven cooling system routes the coolant from the cylinder head through the frame triangle, directly to aluminum radiators made by WP. 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.
SWINGARM
This state-of-the-art swingarm allows for an optimized mounting position of the PDS shock absorber, providing more progressive action. Furthermore, the cast aluminum design guarantees lower weight and a perfect flex behavior. The single-component casting process also eliminates any inconsistencies and weak points.
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 for compression and rebound with the twist of a dial on the top of the forks. In addition, a sealed hydro-stop guarantees excellent resistance to bottoming-out. Due to high-quality materials and a state-of-the-art production process, the WP XPlor 48 fork – with approx. 300mm of travel – has outstanding response and damping characteristics. A comfortable preload adjuster is Six Days standard and allows for a simple spring preload setting in three steps without tools (standard, +3mm, +6mm).
WHEELS
The EXC-F's 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.
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 more space for the exhaust system. A second piston works together with a closed cup (instead of a needle) towards the end of the stroke and is supported by a progressive shock spring for exceptional bottoming resistance. Various machined and anodized components and a distinctive WP color trim make this a valuable, high-end product compared to the less refined shock absorbers of the competition.
FUEL TANK
The lightweight polyethylene tank has a capacity of 8.5 liters. You will always be able to see how much fuel remains at a glance, thanks to the see-through plastic. By pushing the orange release button in the center of the fuel tank cap, the bayonet mechanism makes refueling quick and easy. 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.
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 in a quiet way. The large Twin Air filter is mounted in a stiff cage, which at the same time holds the system in place. This design is so simple; you can pop a fresh one in with a face full of mud – without tools and in seconds.
HANDLEBAR
KTM engineers know how to handle handlebars. This tapered unit, made of high-strength aluminum by NEKEN, features a throttle assembly with a robust aluminum body and easy free-play adjustment. An ODI volcanized grip sits on the right, while on the left side of the bar a comfortable ODI lock-on grip requires no glue or wire to secure it. You can retrofit two interchangeable throttle cams, for different response characteristics to suit your specific needs. With the standard map select switch you can select an alternative power characteristic and activate the unique traction control, a major benefit under wet riding conditions.
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.
FOOTPEGS
Sophisticated´No Dirt´ footpegs prevent jamming up of the pegs, even when digging in deep ruts. The pegs on the EXC models are 6mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.
SIX DAYS EQUIPMENT
