The limited production of ten units features a host of RIVA Performance Products perfectly matched to the Yamaha GP1800R SVHO platform. Each unit features exclusive hull graphics and black anodized components. Under the hood, a powder coated red valve cover equipped with engraved production number plate (1-10) emphasizes the limited nature of this watercraft. The engine produces a reliable 350 horsepower which delivers incredible acceleration and top speeds up to 86mph. To complement the added power, the unit includes upgraded steering and handling components for complete rider control. The RIVA GP1800R SVHO Limited Edition is a race ready muscle craft built for the track or local buoy course.

We don’t claim to be the undisputed kinds of custom-built watercraft - although we’re pretty damn good at it. It’s safe to say that the watercraft we do build are a good representation of what we love to do - take great watercraft, and turn them into a badass racing machine. These watercraft are built in-house by our very own master technicians and guaranteed to make your buddy’s heads turn when you speed past them on the course.
