790 Duke (2017+)

The KTM Duke 790 was introduced to the motorcycle market in 2017 and has received rave reviews ever since. The 790 Duke is KTM's first parallel twin model and was described by MCN as 'a track day tool one day and a commuter the next'.

This naked 790cc motorbike is a great choice for leisure riders, track day enthusiasts and commuters alike. All of our UK road legal motorbike exhaust ranges are available for the Duke 790 motorcycle models and in a couple of exhaust sleeve lengths, giving you the option to really personalise your ride.
