The KTM 125 DUKE may be the entry-level bike of the range, but it isn’t here to play games. This no-holds-barred urban warrior uses its 4-stroke single cylinder engine as a battering ram, smashing its way to the top of the 125 cc class.

Fuel-injection, a 6-speed transmission and class leading performance ensure that it stays there.

Spawned from THE BEAST, it’s no surprise that, from the very first impression, the KTM 125 DUKE holds its own on the streets. With a big bike feel, steel fuel tank and impressive LED headlight for better visibility in low light conditions, you know you’re in for a thrilling ride once you’ve taken a seat and cracked the throttle open.

The KTM 125 DUKE may be small in stature, but it packs a fierce bite. KTM PowerParts only serve to give it more teeth.


Made from hardwearing plastic and secured to the axles, these crash bungs save the axles and protruding parts from severe damage in the event of an accident.
