2006 KTM 990 Duke RR

2006 KTM 990 Duke RR sits at the sharp end of KTM's street-naked experiment, the limited-run version of the big Duke that pushed the LC8 v-twin platform harder than the standard bike ever did. This is not a commuter that happens to look aggressive — it's a stripped-down, upright brawler built around a torquey v-twin that pulls hard from low revs and rewards riders who like to throw a bike into corners rather than lean back and cruise. The riding position is aggressive enough to remind you this is a performance machine, and the chassis responds to input quickly, sometimes nervously, which is part of the appeal for the right rider. The 2006 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2005 example should focus on mileage, service history, and condition rather than spec differences. Expect maintenance costs and parts availability to matter more than most twins in this class. Owners tend to be experienced riders stepping away from inline-four supernakeds, drawn to the v-twin character and the rarity of the RR variant, with moderate collector interest building as clean, unmolested examples become harder to find.
