The design focus of the Sooner Racing Team in 2009 was to improve vehicle mass properties, integrate the new Aprilia RXV 5.5, improve the overall aerodynamics package, and achieve a total vehicle weight goal of under 400 pounds. With the complete overhaul of the chassis, the larger frame increased vehicle stiffness and the repackaging of components reduced the overall vehicle CG height by 10% and the polar moment of inertia by 15% from previous design. First drive was completed on February 14th and vehicle unveiling was March 13th, 2009.
