Before I bought my BMW last year I rode both and here are my thoughts
Both bikes are almost the same except:
Bmw has 20 more HP, 3 year warranty, Much better color options, and a QS.
Street and Backup track- 2012 KTM 1190 RC8R- White and Orange, Dominator exhaust, Bazzaz with TC and QS, Ohlins suspension, Sato Rearsets, GBR race covers
Track- 2011 BMW S1000RR with ABS, TC, and Race Assist. BST Wheels, Shorai Battery, Full Akrapovic Exhaust, Bazzaz, Full Ohlins suspension, Vortex Rearsets, BMC Race Filter, Pazzo Racing Levers, Yoshimura Case Protectors, Stomp tank Pads, Puig Windscreen, Frame Sliders and Fender eliminator
