2021 KTM 85 SX 19/16, 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.
Crankcases And Engine Covers: 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.
Transmission: The 85 SX features a light and robust 6-speed gearbox. The gear ratios have been developed to perfectly match the characteristics of the engine, while easy and precise shifting allows the rider to select the next gear quickly and confidently. The gearbox features a new drive shaft which uses a screw for front sprocket fixation and diaphragm spring instead of a circlip, ensuring secure front sprocket fixation. Another highlight of the 85 SX transmission is the "no-dirt" gear shifter. Similar to the footpeg design, it prevents the build-up of dirt and ensures the next gear is always available, no matter what the conditions.
Clutch: The KTM 85 SX features a strong and reliable clutch with an extremely compact design. The clutch is easily actuated by the FORMULA hydraulic system, which conveniently ensures that play is always compensated for, keeping the clutch "bite" point the same throughout the ride and under all conditions.
Crankshaft: The KTM 85 SX features a lightweight crank
