2012 KTM 125 Duke Picture

2012 KTM 125 Duke Review - "Single" is KTM’s traditional recipe for the greatest entertainment. The latest LC4 engine adds even hotter spices to the mix, uniting previously unattainable refinement with sensationally cultivated manners and perfectly controlled power. The secret: a new cylinder head with dual ignition and individual, selective mappings for each plug make our most popular engine the best Duke powertrain ever. The result: a whopping 70hp, a mountain of torque, as well as a throttle response and NVH on the level of multi-cylinder engines

An extremely rigid and super-light trellis frame made from chrome-molybdenum steel sections and a new, state-of-the-art Bosch 9M+ ABS that combines an extremely dynamic tuning with shorter braking distances ensure precision and stability in every situation.

Following the KTM 125 Duke with its incomparably successful debut all over Europe in spring 2011, the successor of one of the most successful 1-cylinder motorbikes of all times was created in Mattighofen – the 690 Duke. Its message: Singles are fantastic. Welcome to the new Duke world – individual riding enjoyment, more versatile than ever.
