In 1985 Yamaha introduced the V-Max. The first generation V-Max engine was a modified version of the one used in the earlier 1198 cc version of the Venture Royale. The Vmax was equipped with the V-boost system that the Ventures never received reported to add a full 20 horsepower to the Vmax offering. The Vmax sold in the US was equipped with a lower geared drive unit as well which gave it better acceleration but made it a feel a little "busy" on the freeway. The Royale model is the Venture with additional accessories and weight.
