The first 125cc KTM for the road – for all young people and the young at heart alike. The 125 Duke offers maximum riding fun, thanks to thoroughbred motorcycle technology. The featherweight chassis with high-quality components and first-class brakes guarantees dynamic cornering fun. The refined four-stroke single cylinder with fuel injection and six-gear transmission provides adequate propulsion. And the low fuel consumption ensures a reasonable level of economy. Precisely what you'd expect from a genuine KTM. Also available from 2012 in a stylish grey.
