645 SUV Series II

World Premiere 2026

First launched in 2021, the 645 SUV Series I firmly delivered on the promise of freedom and adventure on a grand scale. Now a new generation of these uniquely specified luxury motor yachts has arrived. The Riviera 645 SUV Series II is the result of a whole-of-craft refinement approach to the interior creating a new design and aesthetic that is both contemporary and timeless.

Everything about the 645 Series II is impressive. From the expansive water sports cockpit to the spacious, single-level luxury of the alfresco deck flowing through to the saloon. The accommodation deck is equally generous with a choice of three or four staterooms, three bathrooms, a full-beam master suite and a utility room or crew cabin. And few boating experiences compare with the thrill of being in command of one of these exceptional craft.

The 645 SUV Series II is even more functional, more luxurious and more enjoyable.
