Looking for the closest thing you can get to a street-legal racing bike? Check out the new BMW S 1000 RR ($TBA; 2010). This nasty new superbike features a water-cooled four-cylinder inline power plant good for 193 hp, factory ABS, an advanced traction control system, an HP Gearshift Assistant for full-power clutchless upshifts, all while weighing just 455.3 pounds with a full tank of gas. The result? The most horsepower and highest power-to-weight ratio of any bike in its class.
