• 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 KTM 85 SX has a bore and stroke of 47/48.95 mm.

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.

The gearbox features a new drive shaft which uses a screw for front sprocket fixation and diaphragm spring instead of a circlip, ensuring secure fron
