2015 KTM 250 XC
KTM introduces its 2015 XC Model Line-up:
NEW FOR 2015
Chassis:
*New machined cross tube in the frame that provides a stronger more accurate connection of the frame and the linage due to an improved production process resulting in a 60 gram weight reduction. The frame is now powder-coated in KTM Factory orange
*New linkage geometry with an improved rising rate, better control, stability and balance
*For the linkage there is now an improved production process for higher quality resulting in a 40 gram weight reduction
*New updated WP 4CS fork are 8mm longer for 2015, same length as 2105 SX models, a new style hydro stop and redesigned pistions with a stiffer chamber spring, also with new settings developed in the US specifically for offroad racing.
*New fork lugs with a 22mm front axle for reduced weight and better feel along with a 2mm reduced off-set for improved handling
*New fork protectors with an open design, which are easier to replace for better maintenance and cleaning of the fork leg
*New monoshock setting, which has been re-valved and set-up to match the new linkage and fork. The shock features a 4mm increase of shaft travel while maintaining the same amount of wheel travel with the new linkage package
*New Dunlop GEOMAX AT81 tires for excellent traction
*New aluminum O-ring support for the lower bearing on the steering stem for a weight saving of 22 grams and a new steering stem bolt, which is also 8 grams lighter
*New fork protectors with an open design, which are easier to replace for better maintenance and cleaning of the fork leg
*High-quality Giant rims with new black anodizing for aggressive look and high performance
*New softer two-compound grips
Frame
(NEW)
The improved, modern and lightweight frame design manufactured by WP Performance Systems is made from lightweight, high-strength chromoly steel sections. The design for MY 2015 now has a new machined cross tube that unites the two sides of the frame and connects the linkage rods to the frame. This provides exact production tolerances and consistent chassis characteristics thanks to the absence of welding. It is also lighter (58 grams) than the previous cross tube design. All XC models come with a built in side stand on the frame.
Swingarm
Created using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm have been refined for minimum weight at optimum stiffness and precisely defined flexibility provides perfect stability, which gives excellent traction, stability and comfort.
Rear suspension
(NEW)
The new fully adjustable rear monoshock by WP Suspension has been re-valved and set-up to match the new linkage geometry and 4CS fork characteristics. Also for this year, there is a 4mm longer stroke while maintaining the same amount of wheel travel.
Linkage
(NEW)
The suspension package features a new linkage with revised geometry, due to the development and testing done by the USA R&D development team. These revisions allow for an optimized rising rate that utilizes a higher starting rate to achieve a flatter, less progressive curve for better control, as the rear end of the machine is slighter lower. The innovative production process of the triangle and pull-rod saves 40 grams of weight, while improving the quality of the component.
Front suspension
The XC model range features the WP 4CS fork for the second year. For 2015 the 4CS forks are 8mm longer, same length as the 2014 450 SX-F FE and the 2015 SX models, there is a new hydro stop design and also new pistons inside the cartridge, also there is a new 20N/mm chamber spring up from 18N/mm spring used in 2014, also there is a new setting specifically developed for racing cross-country in the US with more comfort and traction and better bottoming reserve. The forks can be adjusted easily for compression and rebound via the dials on the top of the fork tubes.
Front Axle
(NEW)
The front axle has been reduced in size from 26mm to 22mm to reduce weight and offer a better front-end feel. Also with the smaller axle it was possible to move it back 2mm in the axle clamp. The adjusted offset and increased trail provide more stability.
Front fork protectors
(NEW)
The fork protectors have been revised for MY 2015 to be lighter and fit to the new axle clamps. They allow easier access to the fork legs for quicker cleaning and faster maintenance.
Triple clamps
Top quality CNC-machined triple clamps have been something of a KTM trademark for years. Offering a precise handling with maximum performance, they particularly support the flex characteristics, and with it, the forks’ action. The O-ring support for the lower bearing on the steering stem has been revised and is now made of aluminum to save 22 grams, while the steering stem bolt is now also 8 grams lighter.
Bodywork and graphics
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. For MY 2015, the bodywork will be decorated with updated graphics to highlight the racing character of the MY 2015 XC range of cutting-edge offroad racing motorcycles.
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.
Airbox
The airbox design offers maximum protection of the air filter against dirt, while providing maximum airflow for high performance. The TwinAir filter can be changed without tools in seconds, which is a standard feature by KTM for fast and efficient maintenance.
Wheels
(NEW)
The 21in and 18in rims are now colored in black for aggressive looks and use lightweight, CNC-machined hubs, high-end Giant rims and black spokes with lightweight silver aluminum nipples to achieve maximum stability at minimum weight. The wheels are fitted with the latest offroad tires from Dunlop, the GEOMAX AT81, which have been developed with the Factory FMF/KTM offroad team in the USA.
Sprocket
(NEW)
The new sprocket design is 50 grams lighter and contributes to the overall refining of the MY 2015 XC range.
Handlebars
(NEW)
All XC models are fitted with a new black anodized Neken tapered handlebar, with a bend that is specifically suited to the requirements of offroad while boasting superior quality and performance. The proven standard KTM mount allows the handlebar to be mounted in four different positions. A large Neken bar pad offers effective protection for the rider.
Hand Guards
(NEW)
Standard for all XC models, the hand guards use a new material for better impact resistance
Hand grips
(NEW)
New, softer two-compound grips are used on MY 2015 XC models for increased comfort and less stress on the rider’s hands.
Exhaust
KTM works with WP systems to produce the highest quality exhaust systems to maximize engine performance and meet racing sound levels.
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 motocross, they remain unchanged for MY 2015.
250 XC-F
The 250 XC-F is built for the XC2 Pro Lites GNCC Championship, wining the XC2 class year after year and developing future champions

TWO-STROKE
Two-stroke offroad racing motorcycles have remained an important part of KTM’s heritage. Not only do two-stroke bikes offer generally lower maintenance costs, KTM believes that the lightweight, easy handling machines are critical for offroad racing. KTM is the only major manufacturer that continues to develop its two-stroke range year-to-year while generating new technologies to further improve the handling and performance of these machines, which are proving to be ever-popular on practice and race tracks worldwide.
250/300 XC
With enough power to excel on all sorts of tracks and terrain, combined with an extremely lightweight chassis, the two stroke XC’s have one of the best power-to-weight ratios. The unrivalled performance of the lightweight two-stroke engine makes them a true contender against the more complex four-strokes. For MY 2015 the clutch basket has been reworked, making it lighter.
Benefits
*NEW clutch basket for weight saving
*Unbeatable power-to-weight ratio
*Less weight and more agility than the more complex four-strokes
*6 speed XC semi-close ratio gear box
*Both electric start and kick start
*DDS hydraulic clutch system for effortless and flawless clutch action
