2005 Yamaha Road Star 1700 Midnight Warrior User Ratings

Nestled in a sick aluminum double-cradle frame (the only non-steel frame in the bunch) is an air-cooled 102-cubic-inch, 48-degree V-Twin. It twin-plug-per-cylinder design has a bore and stroke of 97mm x 113mm and a compression ratio of 8.3:1. The air/fuel mixture is fed to the cylinders via a twin-bore electronic fuel injection system with throttle position sensor. Interestingly, the potent Twin is an amalgamation of new technology and classic V-Twin engine theories, as evidenced by its old-fashioned air-cooling and pushrod valve actuation.
