BEFORE THE GATE

Adjustablity

The 2025 KTM 65 SX is designed to grow with the little racer, by being height adjustable. Different adjustability options were built into the KTM 65 SX construction using scientific statistical data and manikins. So, finding the right fit for your little ripper is ultra easy, thanks to height adjustable suspension, handlebar position, subframe, and bodywork, taking the seat height from a low 715mm, to a taller 760mm.

Ignition

A digital ignition from Hidria finds its way onto the 2025 KTM 65 SX, with improved processing power and ignition curve, making for a cleaner burn and smoother power delivery.

Carburetor

A proven Mikuni TM 24 carburetor takes a prime position in producing the goods in the 2025 KTM 65 SX, with settings that work perfectly in harmony with the engine, exhaust, and air intake design.

START STRONG

Performance

Featuring the latest in 2-stroke technology, the 2025 KTM 65 SX sets the benchmark at the starting gate. Besides using the lightest and most durable materials, the engine features a pressure-controlled exhaust valve that delivers top-level performance through its manual 6-speed transmission. The mounting concept for the crankshaft also makes for easier maintenance.

Cylinder

The 2025 KTM 65 SX features a high-performance cylinder made from lightweight and durable aluminum that incorporates a pressure-controlled exhaust valve (PCEV), providing unrivaled performance.

Transmission

From general durability to overall quality, the transmission maintains the same legendary performance but now presents as a more comprehensive and hardy unit. This is paired with a forged shift lever offering improved functionality, while the reliable and light hydraulic clutch system guarantees even wear and near maintenance-free operation.

Spark Plug

There's no more worrying about breaking the plug, thanks to the 2025 KTM 65 SX featuring a spark plug from BRISK with a longer thread. Also, thanks to this innovation from BRISK, the part number is printed on the spark plugs for easy reading - even while screwed in place.

Easy Servicing

Servicing and general maintenance are made simple, thanks to draining noses for liquids and added service markers on the engine that clearly show where to use washers, making maintenance and service easier than before. Nm markings clearly show how to tighten relevant screws to avoid overtightened or too loose bolts. Many of the screws on the engine case have also been unified to the same screw length on the engine case.

CALM UNDER FIRE

Tank

The KTM 65 SX is ready to fuel the fire in your little ripper with a tank design that compliments the frame concept and bodywork.

Airbox and Filter

The airbox features a conventional suction sleeve made from a hard-wearing polyamide instead of rubber and a Twin Air filter mounting system that features snap locks for easy and intuitive mounting. The Twin Air filter is also placed under the seat and is easily accessible without any tools by simply removing the seat. It also features improved dirt intrusion resistance, with no more dirt falling into the intake tract when changing the filter.
