Previously only building off-road and racing bikes, in the 90’s KTM decided to make a street bike. Falling into the supermoto or naked street bike category, the Duke line has enjoyed a very successful life. Built with the high standards that KTM has become known world-wide for, the Dukes are “ready to race” the moment you purchase one. Coming with exclusive factory installed high performance racing parts, the Duke line features name brands like Brembo Brake systems, Akrapovic Exhausts, Magura Hydraulic Clutches, WP Suspension, and much more. 


KTM Duke 990

In 2013, KTM designed the gorgeous little Duke 125 and set a new global standard by being the first manufacturer to produce a 125cc street bike with ABS.  Don’t let the diminutive size of this bike fool you. With its single cylinder, four stroke, liquid cooled, 125cc engine, this mighty little bike puts out a surprising amount of power. Its specially designed tubular steel frame gives it incredible rigidity while reducing weight. Weighing in at a mere 279.9 pounds, the Duke 125 is a perfect blend of power, weight, beauty, and balance.  The engineering love KTM put in this bike makes it a great choice for everyone from beginning riders to experienced stunters.

KTM 1290 Super Duke

On the opposite end of the spectrum from the Duke 125 lies the “Beast”. Known as the Super Duke, the 1290 monster transforms maximum performance and razor sharp agility into the ultimate riding experience. Its 1301cc, 2-cylinder, 4-stroke, liquid cooled, 180 horsepower engine, combined with its Powder Coated Chromium-Molybdenum-Steel frame, PASC Slipper Clutch, 6-speed transmission, Brembo Brake System, and WP Fully Adjustable Suspension, make this bike a truly impressive work of mechanical art.
