2017 KTM 250 XC, 2017 KTM 250 XC UNRIVALLED 2-STROKE PERFORMANCE With enough power to excel on all sorts of tracks and terrain, combined with an extremely lightweight chassis, the 250 XC has one of the best power-to-weight ratios in its class. The unrivalled performance of the lightweight 2-stroke engine makes it a true contender against the more complex 4-strokes. For MY 2017 the 250 XC features gets an all new engine and chassis based on the ultimate 2-stroke motocrosser, the 250 SX. The cross-country world has a new premix king. Features may include: CYLINDER The cylinder of the 250 XC is fitted with a sophisticated TVC (Twin Valve Control) power valve, providing adjustable power characteristics. The power character can be changed within a few seconds thanks to two supplied springs for different tracks and rider preference. CLUTCH The KTM DDS (Damped Diaphragm Steel) clutch is fitted with a diaphragm spring, which allows implementation of an internal rubber damping system. Together with a lightweight steel basket and the Brembo hydraulic system the DDS clutch offers maximum reliability, excellent modulation and light lever pull. CARBURETOR The 250 XC is fitted with a proven Mikuni TMX 38 carburetor producing the perfect air-fuel mixture. For extreme temperature or altitude the setting can be tuned with supplied jets and needles according to a setting list in the manual. ENGINE The powerful KTM 250 XC engine unites an unbeatable power-to-weight ratio with outstanding performance and extremely easy handling. FRAME The modern frame design of the 250 XC, comprised of lightweight, high strength, chrome-molybdenum steel section tubes, combines maximum longitudinal stiffness with optimum torsional stiffness. LINKAGE/SHOCKABSORBER The linkage system of the 250 XC features a progressive curve with a high initial rate ensuring good stability. The high-end WP 5018 shock absorber guarantees outstanding response and damping characteristics. Compression and rebound damping can be adjusted to the track conditions and the rider's preferences. FORK The XC model range features the 48mm WP AER 48 fork. The setting has been specifically developed for racing cross-country in the US. The forks can be easily adjusted for compression and rebound via the dials on the top of the fork tubes. TRIPLE CLAMPS Top quality, CNC-machined triple clamps have been something of a KTM trademark for years. Ensuring precise handling, they provide proper clamping force for correct flex characteristics, thus improving the action of the forks. For 2017 the upper triple clamp features a newly developed rubber damping system for the handlebar clamp in order to reduce the vibration levels felt through the handlebar. The clamps retain their forward and back adjustability for rider preference. GRAPHICS New modern in-mold grap
2017 KTM 250 XC-F, 2017 KTM 250 XC-F SMALL-BORE DOMINATION Already known for its strong performance, the new generation 250 XC-F presents itself with a newly developed, stronger engine built into an all-new chassis. The performance combination of a powerful and much torqueier engine in a lightweight and agile chassis is sure to make the 250 XC-F the star of the show for the future. Features may include: ENGINE The new 250 XC-F engine is based on the similar overall design of its predecessor, with some major refinements to make this power plant more compact and lighter, with the production of improved torque and power across the entire rpm range. Perhaps one of the most impressive benefits of the new design is a weight reduction of 2 lbs, while still including the incredibly beneficial electric starter. The reworked engine guarantees an improved power curve over the entire rev range up to 14,000 rpm, which makes the new 250 XC-F a winner for both amateur and professional riders. CYLINDER HEAD The centerpiece of the compact DOHC (Double Overhead Camshaft) engine is the new cutting-edge cylinder head. It features improved combustion chamber geometry, two 150 g lighter overhead camshafts with new timing, plus a friction-optimized super-fine surface, new finger followers with a 30 % harder DLC coating and a reworked timing drive (friction reduced and shorter DID timing chain, new sprockets and chain guides). New valve springs and retainers for the four lightweight titanium valves (intake 32.5 mm, exhaust 26.5 mm) and high-flow ports create a maximized flow rate for an optimal power band and maximum performance, all the way up to a redline of 14,000 rpm. CYLINDER & PISTON In the reworked and shorter cylinder that has a bore of 78 mm, is a weight-reduced, forged bridged box-type piston made by CP. It features a unique piston shape adapted to the new combustion chamber and stands out with its extra-rigid structure, combined with a low weight. The compression ratio is at 14.4:1. Thanks to the low oscillating masses, the engine offers extremely lively characteristics. COUNTER BALANCER SHAFT In order to balance the mass-forces, the new 250 XC-F engine uses a multifunctional counter balance shaft that also drives the water pump and timing chain. It features new sprockets fitted to the new timing chain. ELECTRIC STARTER The new 250 XC-F is fitted with an electric starter as standard, which a clear advantage in the heat of battle. A new starter motor made by Mitsuba (modified for easy disassembly) and a weight-reduced starter drive guarantees more efficient and reliable starting. ENGINE CASES AND COVER The completely new design of the die-cast engine cases allowed for a much more centralized shaft configuration. The engine is now shorter by 20 mm, contributing to a much more centralized mass. Newly designed engine covers made of ma
2009 KTM 250 XC-W. Right at 60 hours on the motor. Add on's include: Cycra handguards, ASV levers, radiator braces, Moose carbon pipe guard, Moose carbon skid plate, new EBC rear brake rotor and pads, and Pirelli Scorpion XC Mid-Soft tires with plenty of tread. This bike has been extremely well maintained, new gear oil and air filter every 3 hours. Fork seals have been recently replaced. I still have the owners manual and KTM tool bag from purchase. I will also throw in a complete JD Jetting kit and a new battery for the electric starter. You'd be hard pressed to find an '09 in this kind of shape with this few of hours.
