2015 KTM MOTOCROSSERS
2015 KTM MOTOCROSSERS
KTM released its official 2015 line of motocross bikes today. The information for the European models had already been leaked, and the U.S. models are only slightly different. The most significant change is the move to the WP 4CS fork across the line. There are also a number of cosmetic changes that make them all look more like the bikes the Ken Roczen and Ryan Dungey ride. Here is the official info from KTM:
Chassis:
NEW FOR 2015
• 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 WP 4CS fork specifically designed for Motocross
• 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 MX52 tires for excellent traction in all conditions
• 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 high-quality black colored Excel rims for aggressive looks and top performance
• New softer two-compound grips

Frame
(NEW)
(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.
Swingarm
Created using the latest in calculation and simulation software, the design and wall thickness of the cast aluminum swingarm has been refined for minimum weight at optimum stiffness. Precisely defined flexibility provides perfect stability, which gives excellent traction, stability and comfort.
Rear suspension
(NEW)
(NEW)
The new fully adjustable rear monoshock by WP Suspension has been re-valved and set-up to match the new linkage geometry and characteristics. A 4mm longer stroke allows the same amount of wheel travel thanks to the new linkage design.
Linkage
(NEW)
(NEW)
The suspension package features a new linkage with revised geometry due to the development and testing done by the Red Bull KTM Factory Team along with the US R&D department. These revisions provided an optimized rising rate that utilizes a higher starting rate to achieve a flatter, less progressive curve for better control. The innovative production process of the triangle and pull-rod saves 40 grams of weight while improving the quality of the component.
Front suspension
(NEW)
(NEW)
For the United States, the SX model range features the WP 4CS fork. The completely new four chamber fork has been specifically designed and tested for motocross. The advanced 4CS fork offers improved damping, is lighter than previous models and can be adjusted easily for compression and rebound via the dials on the top of the fork tubes.
Front Axle
(NEW)
(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 provides more stability.
Front fork protectors
(NEW)
(NEW)
The fork protectors have been revised for MY 2015 to fit to the new axle clamps, and are also lighter. 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 top quality 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 22grams, while the steering stem bolt is now also 8grams lighter.
Bodywork and graphics
In shaping the bodywork the KTM designers’ ergonomic and design focus was to achieve complete harmony between rider and bike, right down to the finest details. 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 SX range of cutting-edge motocross bikes.
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)
(NEW)
The wheel rims are now colored in black for aggressive looks and use lightweight, CNC machined hubs, high-end Excel rims and spokes with lightweight aluminium nipples to achieve maximum stability at minimum weight. The wheels are fitted with the latest MX tires from Dunlop, the Geomax MX52, which have been developed with the RedBull KTM Factory Racing team and the US R&D department. The tires guarantee excellent traction and outstanding performance.
Sprocket
(NEW)
(NEW)
The new sprocket design is 50grams lighter and contributes to the overall refining of the MY 2015 KTM motocross range.
Handlebars
All SX models are fitted with the super-strong, tapered Renthal Fatbar 827, with a bend that is specifically suited to the requirements of motocross while boasting superior quality and performance. The proven standard KTM mount allows the handlebar to be mounted in four different positions. A large Renthal bar pad offers effective protection for the rider.
Hand grips
(NEW)
(NEW)
New, softer two-compound grips are used on MY 2015 motocross models for increased comfort and less stress on the rider’s hands in every situation.
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 SX-F
The 250 SX-F is once again a World Championship winner in MX2 and adds a prestigious AMA Supercross Lites Championship in 2013 and 2014 to its amazing trophy cabinet.

TWO STROKE
Two-stroke motocross machines have remained an important part of KTM’s heritage and the Austrian brand continues to retain its belief in these products. Not only do two-stroke bikes offer generally lower maintenance costs, KTM believes that the lower capacity machines are an excellent proving ground for youngsters to cut their teeth and learn a strong basis with their motocross skills.
KTM is the only major manufacturer that continues to develop its two-stroke range from 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.
