• ENGINE & EXHAUST

The newest KTM 125 SX engine is its class's most powerful and most competitive engine, a clear sign that KTM is eager to keep 2-stroke technology at the leading edge of development. Their success comes down to an outstanding power-to-weight ratio, low costs and simplicity. This 125cc ripper was developed using KTM's latest engineering know-how along with the most advanced technology available. What it delivers: class-leading power throughout the rev range, in a package that's extremely compact and ultra-light at just 17.2kg. We've done our part; collecting the trophies is now up to you.

• CHASSIS

Shedding weight every year is something KTM engineers simply love. The outcome: the 2018 KTM SX models are the slimmest, lightest dirt bikes around.

• ERGONOMICS & COMFORT

READY TO RACE ergonomics put you at an advantage on the track, ride harder, for longer stretches.

• BODYWORK & GRAPHICS

The plastics were shaped with input from KTM R&D, KISKA Design and every one of our factory riders, all aiming for one thing: complete harmony between bike and rider. On the SX, perfect ergonomics and contact points deliver maximum comfort while moving. Thanks to carefully considered construction and mounting, the I-beam structures of the front and rear fenders guarantee maximum stability and a low weight. They also stay clean longer.
