The mechanism is pretty simple. The first step is of course to buy a set of Pirelli Night Dragon Performance Tires for your V-Twin.
Then you can register at www.getpirelli.com/nightdragon for winning V-Twin performance accessories (Performance Machine Wheels, Boyesen Power X Wing, Roadhouse Exhaust System, Danny Gray Seat, and Kicker Audio Speakers).
According to a Pirelli press release, the Night Dragon tires are based on racetrack technology of World Superbike, designed to meet the needs of V-Twins built with oxen power and torque.
