2017 KTM 85 SX Highlights

The riders of the junior class are no longer beginners. These are future champions fighting for victory, no matter if it is the AMA Amateur National Title or Junior Motocross World Championship. In this scene, the 85 SX is considered the weapon of choice. With the most powerful engine in the field and a super lightweight, stable chassis, the only real competition comes from others racing on the 85 SX.

Highlights
The 85 SX benefits from cutting-edge 2-stroke technology and a precise 6-speed transmission with a hydraulic clutch for superiority on the race track.
The Formula braking system with radial calipers, four pistons in front, two in the rear, matched with lightweight Wave 240 mm front and a 210 rear brake disc set the standard in terms of controlled action and braking performance.
What is good for the bigger KTM off-road bikes is also good for the 85 SX – an air filter change can be done within seconds without tools.
Made of top quality chromoly steel with a lightweight, bolt-on aluminum rear subframe, the 85 SX frame ensures maximum stability at a minimum weight
WP 43mm upside-down forks provide 270mm of travel, while a PDS monoshock for the rear provides optimum traction and surface contact.
Ergonomics and function of the bodywork is designed in such a way as to achieve complete harmony between rider and bike.
NEW graphics provide a sleek and up-to-date look bases on the full-sized SX line.
