With the pro ranks within reach, the KTM 85 SX offers a real taste of the big league of motocross. Following in the footsteps of champions, every inch of this motorcycle mimics the proven design of the big bike range. A lightweight, WP-engineered frame houses its compact “rocket ship” of an engine, which delivers unrivalled performance and rideability. This mini warrior is the ultimate race weapon and is ready to go out and conquer all in the fight for the top step of the podium.

For the 85cc, KTM has successfully developed a chassis that not only handles the hard-charging brutality of a 15-year-old, but also effectively accommodates a lightweight newcomer to the class. This is achieved through its lightweight, high-tech steel frame. Its optimized flex characteristics provide a great feeling for the rider and help to soak up those big hits, while also delivering excellent agility and high-speed stability. Every element is designed to work in perfect harmony and contributes to an intuitive ride like no other.

It took extreme levels of ingenuity to fit the race-winning formula of KTM’s bigger 2-strokes into a compact 85 cc engine. A special manufacturing process is used and provides impressive weight savings without sacrificing strength or durability. The super compact power plant is fitted with a 6-speed gear box and delivers class-leading power and rideability throughout the entire rev range. The power valve plays a key role in tailoring power delivery to suit track conditions and rider ability, ensuring that the only rider surprised by the incredible performance is the competition.

The cylinder on the KTM 85 SX has a bore and stroke of 47/48.95 mm. It features a sophisticated power valve system, which controls both the exhaust valve and the sub exhaust ports, giving the bike excellent torque and power delivery. This translates into significant midrange performance, reducing the need to overwork the clutch in loamy or sandy conditions. An adjuster screw allows the opening time of the power valve to be adjusted to suit rider preference and track conditions.

The crankcases are manufactured using a high pressure die-cast production process, keeping wall thickness to a minimum while retaining strength and durability. The design of the cases is very compact and aims at positioning the shaft arrangements as close as possible to the center of gravity, contributing to better handling.

The KTM 85 SX front fork features the same suspension technology found in the full-size motocross range. The WP XACT AER fork consists of a split fork design with a capsuled air spring in the left leg and the trusted oil damping system in the right leg. It offers a significant reduction of 1.0 kg in weight over conventional spring forks. Importantly, the preload adjustment is extremely simple and can be adjusted by using the single air pressure valve and supplied air pump. The design also allows for easy access to compression and rebound clickers.

The KTM 85 SX features a WP XACT PDS (Progressive Damping System) rear shock absorber. The design offers a high progression rate and excellent response. It allows an impressive 305 mm of rear wheel travel and is fully adjustable for preload, compression and rebound.

Black Excel rims and CNC-machined hubs ensure the strongest base of forward momentum on the KTM 85 SX. MAXXIS tires have been fitted to deliver exceptional straight-line stability and excellent traction on a wide variety of terrain, ensuring the power ends up where it is intended – on the ground.
