Erik Buell Racing's 1190RX is the real deal—a high-horsepower machine meant to excel on the track and awe on the street. It costs $18,995, has a beast of an engine, and it's handmade in the heartland. (UPDATE: EBR is running a "spring clearance event" on 2014 1190RX and streetfighter SX models. The discount is $2,000 on the SX and $4,000 on the RX, making both $14,995.) The RX is almost overflowing with ingenuity and technology, and it's all aimed at turning fast laps. Zack Courts vetted the RX on the track at Jennings GP in Florida (see "Prescription Filled," here), where he was impressed with the bike's poise, power, and traction-control system. That first taste left open one critical question: How does such a purposeful machine perform on the street, where the majority of buyers are bound to ride it most? That's why we spent a couple of weeks in the saddle, commuting on the freeways and carving up SoCal's many legendary canyon roads—living with the bike like you would—to find out.
