The biggest V-twin that Yamaha builds sits menacingly in a double cradle frame. Two 95mm pistons slide over a trick ceramic coating for a stroke of 113mm, yielding a displacement of 1602cc. Feeding the monster motor, a 40mm CV carburetor breathes through the triangular airbox mounted to the right side of the engine between the pushrod tunnels. Yes, those twins made in Wisconsin don't sell the only pushrod engines on this continent anymore. A belt drive not only adds to the Road Star's classic style, but also prevents the jacking effect often present in shaft driven big twins. Feeding the beefy engine is an equally beefy 5.3 gallon tank.
