01.Before the gate

Fit the bike to the rider, not the rider to the bike.

4 features
2027 KTM 65 SX — Adjustability

Find the right fit

Adjustability

Designed to grow with the rider: height-adjustable suspension, handlebar position and bodywork, worked out from real statistical data on young riders. Finding the right fit takes minutes, and the bike stays right for more than one season.

2027 KTM 65 SX — Carburettor

The heart

Carburettor

A proven Mikuni TM 24 carburettor with settings matched to the engine, exhaust and intake — simple, tunable, and known by every mechanic in the paddock.

2027 KTM 65 SX — Ignition

Clean burn

Ignition

Digital Hidria ignition with more processing power and a better curve: a cleaner burn and smoother delivery. A stabiliser cap on the throttle assembly keeps the cable from kinking.

2027 KTM 65 SX — Kickstarter

Little legs, easy start

Kickstarter

A lighter, more ergonomic kick lever shaped to the frame and engine — easy to reach for a quick restart, and out of the way when the rider is on the pegs.

02.Start strong

The benchmark 65 engine: pressure-controlled exhaust valve, six speeds, hydraulic clutch.

4 features
2027 KTM 65 SX — Performance

Unmatched performance

Performance

The latest two-stroke technology in the class: the lightest, most durable materials, a pressure-controlled exhaust valve for a broad, usable powerband, and a manual six-speed gearbox that teaches real racing.

  • 6-speedmanual
  • 54.3 kgwithout fuel
2027 KTM 65 SX — Cylinder

Power valve

Cylinder

A high-performance aluminium cylinder with the pressure-controlled exhaust valve (PCEV) built in — light, durable, and the reason the 65 pulls the way it does.

2027 KTM 65 SX — Transmission & clutch

Hardy unit

Transmission & clutch

The same legendary performance in a stronger, more comprehensive unit, with a forged shift lever and a light, reliable hydraulic clutch that works the same on lap one and lap twenty.

2027 KTM 65 SX — Service markers

Easy servicing

Service markers

Drain noses for fluids, ▲ markers on the engine showing where washers go, and Nm markings that tell you how tight — so parents and mechanics get it right without a manual.

03.Calm under fire

A chromoly frame and bodywork scaled from the full-size SX — slim, sleek, built for standing on the pegs.

4 features
2027 KTM 65 SX — Frame

Built tough

Frame

High-strength chromium-molybdenum steel with forged connecting parts and calculated longitudinal flex and torsional rigidity — tailor-made stiffness, and a quality of mini frame nobody else builds.

2027 KTM 65 SX — Ergonomics

Slimmer and sleeker

Ergonomics

The same bodywork thinking as the big SX: slimmer, sleeker, better for standing, with side panels that work with small boots so the rider can squeeze the bike properly.

2027 KTM 65 SX — Handlebars & grips

Get a grip

Handlebars & grips

A tapered black aluminium-alloy bar with a bend and profile designed for 65 riders, and ODI grips — stability, damping and control in small hands.

2027 KTM 65 SX — Airbox and filter

Breathe clean

Airbox and filter

A hard-wearing polyamide intake sleeve instead of rubber, and a Twin Air filter on snap locks under the seat — accessible without tools.

04.Hit the big stuff

WP XACT suspension, Formula brakes and MAXXIS rubber — the full-size parts list, scaled.

3 features
2027 KTM 65 SX — Suspension

Ride rough

Suspension

A lightweight 35 mm WP XACT AER USD fork with 215 mm of travel, adjusted with an air pump for rider weight and track, paired with a WP XACT monoshock adjustable for compression and rebound.

  • Ø 35 mmfork
  • 215 / 253 mmtravel
2027 KTM 65 SX — Brakes

Stopping power

Brakes

Floating Formula calipers with a 198 mm wave disc up front and 180 mm at the rear — low wear, maximum reliability, and a forged rear brake lever for feel.

2027 KTM 65 SX — Wheels & tires

Rip 'n go

Wheels & tires

Lightweight black-anodised aluminium rims like the full-size SX, with MAXXIS MX-ST tires for traction and straight-line stability on any terrain.

05.Maintaining momentum

Cooling and exhaust built the same way as on the full-size two-strokes.

2 features
2027 KTM 65 SX — Radiators

Stay cool

Radiators

Pankl radiators inspired by the full-size SX range, with the same basic design and cooling properties, and a standard thread closure that opens without a fight.

2027 KTM 65 SX — Exhaust

Bring the braaap

Exhaust

Built with the same manufacturing process as the full-size two-stroke SX pipes, with improved silencer end-cap sealing and a rubber joint between header and silencer for durability.

06.Warranty & support

New bikes, delivered through authorised channels, with the paperwork the warranty is tied to.
