After last year’s new generation of SX machine was launched with revolutionary WP AER 48 forks, a new chassis, plus new engines over previous models (except 250 SX), the KTM research and development departments in Austria and United States have been making further improvements for 2017, and updated the 250 SX model to the latest specification of chassis with a brand new engine.
With input from the KTM Motorsports department being influential to serial production, especially in the US where the factory team must race homologated machines and it can be noted Ryan Dungey has just won backtoback 450 Supercross World Championship titles aboard a KTM 450 SXF, the SX model lineup is better than ever.
With typical KTM characteristics including a precisely designed, hightech lightweight chromemoly steel frame, hightech Brembo brakes, lightweight CNC-machined hubs with highend Excel rims, Dunlop Geomax MX 3 tires, NoDirt footpegs, an intelligent air filter box system, precisely designed bodywork and much, much more already fitted to these machines, KTM has once again reached new heights with the latest model range. For 2017, there are a number of refinements over last year including traction control for fourstroke models, which is part of the new multifunctional handlebar map switch, new suspension components and settings, new graphics and other exciting details.
New for 2017 are: the multifunctional handlebar map switch so the rider can activate the new traction control and launch control, while choosing an alternate mapping of the engine management system; redesigned upper triple clamp for enhanced fork action; new shock absorber setting for increased rider confidence; hour meter to help keep up with precise maintenance; redesigned outer tubes on AER 48 forks for enhanced flex characteristics for reduced stiction and less friction, as well as a weight reduction of 265 grams; new graphics; new seat cover that provides a better feel and grip for the rider; new resonator system for 450 SXF with flow design header plus a new 250 SX exhaust system; and new aluminum cylinder head stays on the engine mounts for fourstroke SX models.
“Last year was a new generation of SX, but we’ve been through every component of each motorcycle in this range and as always we’re looking how we can do this better. There are some significant changes in the SX MY [model year]2017 lineup to benefit the rider both on and off the bike, as well as a brand new 250 SX!” said Joachim Sauer, KTM off-road product manager.
“The appetite for improvement never stops in our R&D department and we feel that riders will certainly benefit from the refinements made for 2017,” he added.
