About the 1999 Yamaha Royal Star Boulevard

The 1999 stands for tons of individualist attitude, even though it comes with a passenger seat, too. However, this bike is all about fast, zero-frills rides, with the man behind the bars knowing he’s there to enjoy the road and the freedom.

Powered by the proven, acclaimed V4 engine of the Royal Star family, the Boulevard edition blends in classic retro shapes with modern character. On the old-school side, we’ve got the lush chromed accents, the dual bullet-style exhausts, deeply balanced fenders and chrome triple-headlight array, alongside the studded seats. Cast wheels, top-drawer V4 and dragster-ish riding position are the present-day counterparts.
