The good people over at RIVA Racing have a great opportunity for anyone that wants one of their special editions 350-horsepower monster of a machine. RIVA has a leftover 2020 Sea-Doo RTX–X 350 LTD.The RIVA Racing crew have been putting out stellar limited run skis for several years and for 2020 they one-upped themselves by building a handful of custom-built machines specific to order. These machines are all about high performance and not for the weekend-warrior type. The ski you see here was coined as a 2020 Sea-Doo RXT-X 350.
The watercraft is equipped the full catalogue of performance and handling components – offering slightly more than RIVA’s basic Stage 2 kit – that will dramatically increase the overall ride, acceleration and handling of the standard Sea-Doo RXT-X 300 from which it was based.
The build began with RIVA’s Sea-Doo RXT/GTX Pro-Series Steering System, which will aid in making those hard corners tight and controlled rather than loose and unstable. Next was the addition of the billet iControl Levers. The set for Sea-Doo iControl provides superb control and comfort along with its cutting-edge design. It replaces the OEM plastic parts with high quality CNC machined throttle and brake levers. The set also features a more responsive stainless-steel return for that precision feel.
Rounding out the rest of the handlebar package is RIVA’s 30” Pro-Bar Aluminum Handlebars, which are constructed form a proprietary aluminum alloy that provides maximum strength and reduced vibration. Reduced vibration is a must when traveling at extremely high speeds. Finally, the bars are fitted with the 2019+ RIVA Sea-Doo RXT Control Housing Switch Housing Set. It is designed to work with the original OEM control system in aftermarket steering applications.
The ski will handle extremely well with the combination of the RIVA steering components and the Pro-Series Sponsons. The sponsons offer improved handling and straight line stability with their deep-set blades. They also have a five-way adjustable fin system, which allows the rider to position the fins in ways that will control the overall influence they have on the craft.
The PWC is also outfitted with the Sea-Doo RXT/GTX Power Filter, RIVA MaptunerX ECU Tuning, and Solas Sea-Doo Concord SXX 13/18 Impeller. The Power Filter feeds the heavy-breathing ACE 300 supercharged engine with a constant flow of cool air, which delivers significantly improved acceleration and rpm. The Power Filter replaces the restrictive stock air box so you can go fast! The revised ECU tuner via the MaptunerX software delivers a proven engine tune to keep the ACE 300 running strong throughout the power curve.
The Solas 161 3-blade Concord Impeller increases low-end thrust and top-end speed on the 300-horsepower Sea-Doo models. The Solas impellers are comprised of high strength stainless steel. The impeller features a hub-end water seal, exclusive to Solas. The hub-end water seal reduces cavitation.
The custom ski not only looks great and go fast, but makes some serious noise, thanks to the RIVA Sea-Doo Rear Exhaust Kit. While the kit delivers on performance and cutting-edge style, it allows for the removal of the stock sound suppression.
The RIVA 4-Tec Catch Can/Engine Breather Kit stops power-robbing crank case fumes and oil vapor from the engine’s air intake. This in turn creates more horsepower since it takes away the engine’s need to burn mostly non-combustible oil. The catch can is one more way to increase speed on these two RIVA Sea-Doo custom builds.
A nice addition to the first machine is a custom non-slip RIVA/Jettrim Seat Cover in black with silver stitching. The cover is made with ballistic nylons, ultra grade marine vinyl, and Jettrim’s exclusive Nada-Hyde, non-slip traction material. The custom PWC is rounded out with limited-edition graphics and custom gold anodized parts that sharply play off of each other and really make this machine pop! The overall appearance is bold and powerful. The ski flies across the water at a peel-your-face-off speed of 81 mph @ 8350RPM!
