ADJUSTABILITY
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.
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.
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. A new mounting concept for the crankshaft also makes for easier maintenance.
AIRBOX AND FILTER
An all-new airbox concept features a conventional suction sleeve made from a hard-wearing polyamide instead of rubber and a Twin Air filter mounting system that now 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.
ERGONOMICS
The all-new bodywork of the 2025 KTM 65 SX is the perfect example of KTM's commitment to providing the ultimate starting point for young racers. Mimicking the full-size KTM SX range, the KTM 65 SX features the same advancements found in the larger KTM SX classes. Slimmer, sleeker, and better suited to standing on the pegs, the side panels now work much better with young riders' boots, allowing proper squeezing of the bike when standing up. The front number plate incorporates plastic flaps to pro
HANDLEBARS & GRIPS
Hold on tight! The high-quality, tapered, black handlebar is made of lightweight aluminum alloy and ensures top stability, vibration damping, and control. It has been designed specifically with 65cc riders in mind, featuring an entirely new bend and profile, forcing a more READY TO RACE body position. ODI grips are mounted on the left side, while a vulcanized ODI grip is mounted on the right-side throttle assembly, with a crash pad on the handlebar protecting the rider from rough contact.
FOOTPEGS
All-new, "no-dirt" footrests offer a bigger surface area for improved grip while standing on the pegs and are less susceptible to hooking up in deep ruts, take-offs when scrubbing, or track barriers.
EXHAUST
A completely new exhaust system, features the same manufacturing process as the full-size 2-stroke KTM SX range, with improved overall quality and performance. This has resulted in massive improvements in thermodynamics. Moreover, improved sealing of the silencer end cap and a new rubber between the header pipe and silencer adds another level of quality to the new exhaust system. The silencer has also been updated and now comes with a black anodized finish and a signature 'Braaaaap!'.
