2015 KTM 150 SX, In Stock 2015 KTM 150 SX !!!! 2015 KTM 150 SX THE BEST OF BOTH WORLDS. In MY 2015, the 150 SX can bare its teeth even more effectively at the 250cc 4-strokes with its strengthened engine not least, thanks to its unbeatably low weight. Standard Features May Include: ENGINE The engine on the 150 SX 2015 has been upgraded with an optimised ignition curve in order to achieve more effective combustion for better power development and optimum rideability. BRAKES High-tech brakes from Brembo have always been standard equipment on KTM offroad bikes and, together with the lightweight wave brake discs, they are the measure of all things in terms of brake technology. As the best brakes in the motocross class, they remain unchanged for MY 2015. WHEELS The wheels fitted for MY 2015 feature black coated, high-end Excel rims with lightweight, CNC-machined hubs and spokes with lightweight aluminium nipples, allowing highest levels of stability to be achieved, while keeping weight to a minimum. New Dunlop Geomax MX 52 tyres were developed in collaboration with the KTM USA factory team and offer perfect traction with top performance. The new rear sprockets save 50 grams in unsprung mass. LINKAGE / SHOCK ABSORBER The revamped damping system for MY 2015 features a new linkage with optimised geometry. The flatter progression with a higher initial rate ensures greater stability and lowers the rear end. In addition, the new design saves another 40 grams of weight. The fully adjustable WP 5018 shock absorber has been completely retuned to suit the new linkage. FORK The fully adjustable upside-down fork from WP Suspension has been perfectly tuned to the new rear wheel damping system and the new 22 mm front axle (formerly 26 mm) for MY 2015. The new axle provides a better feel for the front wheel and also saves a further 40 grams. The new fork stubs now feature an offset of 33 mm instead of 35 mm, which together with increased trail deliver greater ride stability. Furthermore, they accommodate newly developed, 50 gram lighter fork protectors.
