2016 KTM 250 XC-F, FRESH OFF COMPLETE CHASSIS AND ENGINE OVERHAUL. NEW TOP END AND ALL NEW BEARINGS, FRESH SUSPENSION REBUILD. CLEAN BIKE!! 2016 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: ENGINEThe 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.ENGINE MANAGEMENT SYSTEMThe completely reworked Keihin Engine Management System with electronic fuel injection features an all-new 44 mm throttle body, which provides instantaneous response and maximum performance thanks to a revolutionary injector position. The new ECU (Engine Control Unit) includes a launch control for more efficient starts with the provision of different maps according to the gear sensor selection. In addition, the rider can activate an optional map for a different power delivery via the map select switch on the handlebar.CYLINDER HEADThe 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.BRAKESHigh-tech Brembo brakes have always been standard equipment on KTM off-road bikes, and now are combined with newly designed and weight-reduced Wave discs made by GALFER featuring improved heat resistance. Weight reduction is 63g on the front disc, and 32 g for the rear. This is the ultimate solution in braking technology.FUEL TANKAll XC-F models have new lightweight polyethylene tanks fitted with an integrated fuel pump system and capacity of 2.25 gallons.

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
2015 KTM 250 XC-F, 2015 KTM 250 XC-F XC-2 DOMINANCE Features May Include: ENGINE MANAGEMENT SYSTEM (EMS) In combination with the revolutionary injector position as developed by KTM, the Keihin Engine Management System with electronic fuel injection and 44mm throttle body provides spontaneous throttle response & the possibility to change characteristics or read engine data with the PowerParts User-Setting-Tool. With an optional map-select switch from the PowerParts program the EMS allows for selecting different engine characteristics. In addition, the optional User-Setting-Tool provides the ability to analyze engine data with a laptop and change the ignition and injection mappings with a few mouse clicks. CYLINDER HEAD The centerpiece of the compact DOHC engine is its cutting-edge cylinder head with two overhead camshafts and DLC-coated followers a design that allows to break the engine speed sound barrier of 14,000 rpm. CRANKSHAFT The 250 crankshaft employs a plain big end bearing. Two force-fitted bearing shells run directly on the crank pin. This design is a major prerequisite for the extremely high engine speed levels and the unrivaled maximum power of the 250cc engine. It enhances the engine s durability, allowing a longer interval between crankshaft service. BALANCER SHAFT In order to balance the mass-forces, the 250 engine uses a multifunctional counter balance shaft which also drives the water pump and timing chain. The engine receives a new water pump cover with a new gasket in order to optimize the seal. BODYWORK In shaping the bodywork the KTM designers ergonomic and design focus was to achieve complete harmony between rider and bike. The front fender is a prime example of a molded polymer component, gaining maximum stability through a well thought-out structure and mounting system. FUEL TANK The XC s feature a large 2.6 gallon translucent fuel tank on the two stroke XC s and a 2.4 gallon translucent fuel tank on four strokes. The 1/4-turn fuel cap is easy to open and provides extremely quick refueling during a race. AIR BOX The airbox design offers maximum protection of the air filter against dirt while ensuring maximum airflow for top performance. The Twin Air filter can be changed without tools in seconds, a standard for KTM. HAND PROTECTION AND GRIPS Standard for all XC models, the hand guards use a new material for better impact resistance. New, softer two-compound grips are used on MY 2015 XC models for increased comfort and less stress on the rider s hands. BRAKES High-Tech Brembo brakes have always been standard equipment on KTM off-road bikes, and combined with the lightweight Galfer Wave discs, they are the ultimate solution in braking technology. Being the class-leading brakes in offroad, they remain unchanged for MY 2015. WHEELS
