The 1190RS is much more than a reskinned 1125R. Essentially every component has been improved based on data gathered from the Buell 1125RR that Geoff May races in AMA Superbike competition. The aluminum frame still holds 4.5 gallons of fuel, but it has been redesigned to accommodate a larger ram-airbox and geometry has been "normalized" with a longer wheelbase, less rake and more trail. The bulbous, side-mounted radiators are gone, replaced with a conventional cooling unit wrapped in slimmer, more aerodynamic bodywork. The 72-degree V-twin has been enlarged to 1190cc and hot-rodded to the hilt, every remaining component optimized to save weight, improve performance and, ultimately, win races.
