Behold the KTM 1290 Super Duke R Prototype in all its glory. The Austrian motorcycle manufacturer showed off its newest concept at the 2012 EICMA International Motorcycle Show, and it boasts an extra 100cc of displacement over the LC8 mill in the 1190 RC8 R on which the prototype is based. That means there's a full 180 horsepower on hand to kick you down the track, and given the impressive efforts at weight saving engineers implemented on the concept, something tells us the sprint to 60 mph will take no time at all.
KTM hasn't released a specific curb weight, but the 1290 Duke R Prototype features a chrome-molybdenum steel tube frame, a light-weight alloy single-sided swing arm and lightened alloy wheels. That's fun and all, but not nearly so interesting as the way this bike sounds. With that big V-Twin barking through an Akrapovic exhaust, the bike sounds like a 55-gallon drum full of lionesses on meth. Check it out in the video below.
