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, high-quality frame houses its compact rocket ship of an engine, which delivers unrivaled 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.

ENGINE & EXHAUST

• ENGINE

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.

• CYLINDER

The cylinder on the 2020 model 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.

CHASSIS

• FRAME

The frame on the KTM 85 SX is a scaled-down version of the championship-proven full-size frames. It is professionally crafted using hydroformed chromium molybdenum steel tubes that are robot welded, ensuring the highest levels of consistent quality. The flex characteristics have been specifically tailored for easy handling and optimal comfort, while working in perfect harmony with the suspension, to ensure excellent agility and high-speed stability. For 2020, the frames feature highly durable orange powder coating and come with standard frame protectors.

• SWINGARM

The one-piece swingarm is manufactured using a gravity die-cast production process for exceptional strength at the lowest possible weight. It offers a wide range of adjustment for the rear wheel, allowing for a shorter wheelbase on tighter, twisty tracks, or a longer wheelbase for greater stability on longer, more choppy tracks. The swingarm's chain measurement markings are visible from above, making adjustment simpler and more accurate.

ERGONOMICS & COMFORT

• HANDLEBAR

The KTM 85 SX features a strong, lightweight, tapered aluminum handlebar, with a specifically shaped bend to suit the overall ergonomics. Additionally, the bike comes standard with ODI lock-on grips, which include a vulcanized grip on the right side and a lock-on grip on the left that do not require glue or wire for mounting.
