ENGINE & EXHAUST
ENGINE & EXHAUST
- Engine: The 250cc 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, and a 13:52 re-gear, the powerplant is even 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.
- Cylinder: The cylinder on the KTM 250 XC-W TPI 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.
- Transmission: 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.
- Engine Management System: The engine management system (EMS) of all 2-stroke XC-W 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.
- Balancer Shaft: The KTM 250 XC-W 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.
- Clutch: The KTM 250 XC-W 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 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.
- Throttle Body: The KTM 250 XC-W 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.
- Oil Pump: Pre-mixing 2-stroke fuel is a thing of the past for KTM XC-W 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.
- TPI Alternator: 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.
- Cooling: Maintaining the optimal engine temperature is crucial to ensuring consistent horsepower throughout the ride. The KTM 250 XC-W TPI features newly designed radiators which are mounted 12 mm lower than the predecessors. This lowers the center of gravity and matches the design of the new 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, a reworked delta distributor, integrated into the frame triangle, features a 4 mm larger center tube, increasing the cross section by 57%, making the coolant flow from the cylinder head to the radiators more efficient. The radiators also feature special protectors that don't only serve as protection from flying rocks and debris but also as a brace that disperses energy around the radiators in the event of an impact.
- Exhaust: When it comes to improved power delivery and performance, the new exhaust plays a key role and packs a punch that is hard to beat. The 250 cc and 300 cc models feature new HD exhaust pipes (heavy-duty) made by using an innovative 3D stamping process which produces a rippled surface finish. This makes the pipe much stronger, with better resistance against rocks, while also helping to reduce noise drastically. The silencer features a new shape and end cap with reworked internal designs individually developed for each model. The plastic silencer holder is now replaced with lightweight, welded mounting brackets. In addition, the exhaust's new shape provides slimmer ergonomics and more ground clearance, while a new perforated inner silencer tube works with lighter damping wool for more efficient and more durable noise reduction. This adds up to a weight reduction of approximately 200 grams.
- Frame: All XC-W models feature new high-tech, lightweight chromoly steel frames. This includes hydro-formed elements produced by state-of-the-art robot welding. They retain their race-proven geometries, but by re-designing certain areas, the stiffness has been optimized, resulting in better feedback for the rider, playful handling and improved stability. The laterally attached engine head stays (the connection between cylinder, head and frame) are now made of aluminum, reducing vibration and further contributing to precise cornering. The bikes also feature newly designed lateral frame guards with a structured surface, improving grip, while also serving as a heat protector against the muffler on the right side. On the KTM 250 XC-W TPI frame, the engine is lowered by 1° around the swing arm pivot improving front wheel traction significantly. The subframe is made of extra-light and stable aluminum profiles, weighing less than 2 lbs (900 gr) and is 40 mm longer than before, providing better rear fender stability.
- Swingarm: The KTM 250 XC-W TPI'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.
- Wheels: The KTM 250 XC-W 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.
- Tires: Dunlop Geomax AT81 tires provide maximum grip, traction, and stability at the absolute minimum weight for unmatched offroad performance.
- Suspension: For 2022, all KTM XC-W models have received a suspension update, with a firmer factory setting focusing on performance and improved consistency across different terrains.
- Front Suspension: 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.
- Rear Suspension: The WP XPLOR shock absorber is the key element in 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 dual-sport 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. For 2020, improvements to the second piston, as well as a reworked shape and sealing of the cup, lead to improved resistance against bottoming without any sacrifice of comfort. New settings on the XPLOR shock with PDS technology provide better damping characteristics and match the new frame and reworked 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.
- Triple Clamp: The 250 XC-W TPI is 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; this XC-W will fit you like your favorite gloves.
- Brakes: These high-tech Brembo brakes are combined with lightweight Wave brake discs. You couldn't brake any harder or with better feel on an offroad motorcycle.
- Fuel Tank: 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-W 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.
- Airbox: 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.
- Handlebar: All KTM XC-W 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, all models can be equipped with an optional handlebar map select switch, which allows to select between a standard and advanced power curve.
- Footpegs: Sophisticated ´No-Dirt´ footpegs prevent clogging up the pegs, even when digging in deep ruts. The pegs on the Enduro models are 6 mm higher than the ones used on SX models, which benefits ground clearance. But you can swap them at will.
- Seat: The XC-W 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.
- Decals: The durable in-mold graphics convey the READY TO RACE character of the KTM XC-W model line.
- Battery & Wiring Harness: All engines are fitted with the proven electric starter, which is a major benefit for any offroad activity. It is powered by a super lightweight 2 ah lithium-ion starter battery which provides safe, reliable starting. A reworked wiring harness and revised packaging has most of the electrical components concentrated into a common area below the seat, making them more accessible and reliable.
