Watch the KTM 1290 Super Duke R Prototype stretch its legs
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.
