The riders of the junior class are not beginners. These are future champions fighting for victory, no matter if it is the AMA Amateur National Title or Junior Motocross World Championship. The 2018 KTM 85 SX is a completely new weapon for class supremacy. An all-new model from the ground up, the 85 SX boasts an engine with more power and ridability across the entire rev range and a chassis that allows the rider to use every bit of that power. There is no 85cc machine that is more READY TO RACE than the 2018 KTM 85 SX.
2018 KTM 85 SX Highlights
NEW engine with improved power and torque over the entire rev range is 1.5 pounds lighter.
NEW cylinder is designed around an all new power valve system that is adjustable and increases torque and controllability.
NEW crankshaft is lighter than before while having more inertia for better torque. Optimized balancing reduces vibrations.
NEW DS (Diaphram Spring) clutch is more compact with better performance than a conventional coil spring design.
NEW crankcases are more compact with a shaft arrangement that is close as possible to the center of gravity.
NEW lighter transmission with the same motocross-specific gear ratios.
NEW chomoly steel frame is nearly a pound lighter with 7% more torsional rigidity and 25% less longitudinal stiffness for more agility and better bump absorption.
NEW WP AER 43 front fork with a sophisticated air spring design and separate damping for easy adjustment to any track condition, rider weight or skill level.
NEW WP PDS (Progressive Damping System) rear shock provides excellent bump absorption and stability.
NEW aluminum subframe is lighter and more compact for better mass centralization.
NEW cooling system features integrated crankcase cooling and two radiators for high performance. The newly designed system uses the shroud and grill to protect the radiator in a crash.
NEW sharp bodywork that is based of the full-sized SX models with the same contact points and overall feel for perfect ergonomics.
NEW airbox similar to the larger SX models allows for air filter changes in seconds without tools.
Black coated high-end Excel rims, lightweight, CNC machined hubs and black spokes with lightweight aluminum nipples ensure the highest stability at minimum weight on the KTM 85 SX.
