A bonus to the release of Factory Editions is they are a reliable preview of what the KTM SX-F models will be for 2016. In fact, e’d bet all the money in your bank account that the 2016 KTM SX-F models will be almost identical to the Factory Editions, inus the graphics and a few of the bling items.We loved the new 2015 450SX-F Factory Edition and are now big fans of the new 250SX-F Factory Edition as well. KTM went all out when designing and building the Factory Editions, reating two of the lightest production motocross bikes ever. The Factory Editions are all about weight loss, ass centralization and improved performance.

The new 250SX-F Factory Edition engine is not only smaller, t’s 2.4 pounds lighter and more powerful. The clutch is raised 26.9mm and moved back 11.1mm. The crank was moved up 6mm and the connecting rod is 6mm shorter. The cylinder is 130 grams lighter and the camshafts are 150 grams lighter, hile the finger followers have a 30% harder DLC coating. Engine changes and improvements allowed KTM to raise the rev limiter to an incredible 14,000 rpm. The clutch basket is revised, o improve oil flow and cooling, nd the clutch now uses seven plates instead of eight. The 250SX-F Factory Edition uses the same 44mm Keihin fuel injection system as its 450SX-F counterpart and the Keihin throttle body no longer uses linkage. New throttle cables feature the adjusters up at the throttle tube housing. An all new exhaust system sources a 40mm shorter muffler that is 60mm closer to the center of mass.

(Above) The 2015 KTM 250SX-F Factory Edition engine is lighter and more powerful. (Middle) The new WP shock is shorter and lighter but offers up more rear wheel travel. (Below) The 2015 KTM 250SX-F Factory Edition doesn’t cut any corners and every component is top quality.The all-new chromoly frame is lighter, eaturing 20% increased torsional rigidity and 30% decreased longitudinal stiffness (identical to the 450SX-F Factory Edition minus the cradle below the engine). These changes help the frame absorb energy created from rear wheel loads and improve overall handling. The head angle is steeper and the wheelbase is 12mm shorter. A new smaller subframe is also 250 g lighter, ontributing to the bike’s 7 pound overall weight savings.

Like the 450SX-F Factory Edition, he WP 4CS fork on the 250 SX-F Factory Edition received more progressive valving, imed at adding comfort. A revised WP shock complements the frame and features a new body with a larger reservoir and a new piston and shock shaft. The shock is now 12mm shorter and weighs less. Even with the shorter shock, ear wheel travel is increased by 10mm due to the longer pull rods and a new linkage system. A rubber mount system for the handlebar is another welcome change, educing vibration and adding to overall front end comfort. There are two mounting positions for the handlebar clamps. The lower triple clamp is designed with more flex for better handling.

A lighter airbox houses a new TwinAir air filter mounted on a cage that features a simple design to minimize incorrect installation of the filter to the cage and installation of the cage into the airbox. It is a quick install system, ven easier than previous KTM models. Even the WP radiators are new, mproving engine cooling by 10%. The redesigned radiator guards improve air flow and increase structural strength significantly. The new lithium-ion battery is 2.2 pounds lighter than the Yuasa lead acid battery and further reducing weight wherever possible, he footpegs and shifter are now lighter. The shifter tip prevents mud from getting into the pivot and the tip is a rounded square shape. Like the 450SX-F Factory edition, he 250SX-F features an engine map switch on the handlebar and also has an integrated launch control system.

Sitting on the new 2015 250SX-F Factory Edition is completely different than sitting on the standard 250SX-F. The seat and handlebar positions are both 10mm lower, nd the footpegs are now mounted 5mm back and 4mm down, reating a bike that feels like no other KTM before it.
