2011 Roehr eSupersport Unveiled
Electric sportbike based on Hyosung GT650R
The 2011 Roehr eSupersport joins the eSuperbike in the Illinois-based companie’s electric sportbike lineup alongside the conventional gas-powered Roehr 1250sc.
The eSupersport is more or less an electric conversion of a Hyosung GT650R, and in fact, except from a variation to the paint, badging and the lack of an exhaust system, visually resembles the Korean sportbike. Using Hyosung’s bodywork instead of its own custom body work (still present on the higher-powered Roehr eSuperbike) will keep production costs lower, though at $17,995, the 2011 Roehr eSupersport will cost $1,000 more than the 2010 model. The eSupersport does qualify for a 10% federal tax credit and some states may offer their own rebates.
The higher price does bring some significant performance improvements to the eSupersport. The big difference is the claimed output of 67hp, a bump up from the 48hp Roehr previously announced for the 2010 eSupersport. Roehr also claims 80 ft-lb. of torque for the eSupersport with a top speed over the 100 mph mark. Powering the AC induction motor is a 96V LiFePO4 battery with a capacity of 7.7 kWh, an upgrade from the 2010 eSupersport’s 5.8 kWh battery. Roehr claims a range of 75 miles and a charge time under seven hours. At 470 lb., the 2011 eSupersport is also heavier than the 395 lb. 2010 model.
The chassis is essentially identical to the Hyosung GT650R. The suspension system consists of a 41mm inverted fork with adjustable rebound and damping and single shock rear with adjustable preload. Stopping power is provided by twin 300mm discs and four-piston calipers up front and a single disc with two piston caliper at the rear.
