Gallery: RIVA Racing Limited Edition 2021 Sea-Doo RXT-X 350 & RXP-X 350


The RIVA Racing crew stayed extremely busy during these pandemic times. The crew upgraded a Sea-Doo RXT-X 350 and a Sea-Doo RXP-X 350, both done in typical RIVA Racing style-big and bold! Both machines were wrapped in head turning purple and neon yellow with a matching custom color seat cover. These machines were outfitted with the RIVA performance products perfectly matched to their respective Sea-Doo platforms. The engine cranks out a reliable 350-horsepower with a top speed of 81mph. RIVA quickly sold out of these Limited Edition Sea-Doos.

Now let’s get down to the nitty gritty of parts. Both custom models were equipped with a RIVA MaptunerX BRP License. The license enables the user to switch between performance and stock settings. A RIVA Sea-Doo 2020+ RXT/GTX 300 Power Filter in order to feed your supercharged engine that much needed steady flow of cool air and greatly improving acceleration and rpm.

The Sea-Doo RXP-X received the 2021 RXP-X 300 Power Filter Kit. To keep power robbing to a minimum, the machines were fitted with RIVA Sea-Doo Catch Can/Engine Breather Kits. These kits are great for eliminating crankcase fumes and oil vapor from the Sea-Doo engine’s air intake and the kits also kick up the horsepower by removing the requirement to burn non-combustible oil.

Supercharged engines have to be kept super cool, so RIVA replaced the factory installed rubber hoses with high strength multi-ply silicone hoses found in the RIVA Sea-Doo 230/300 Intercooler Tubing Upgrade Kit with TIAL 50MM Blow-off Valve. The machines needed vacuum port adapters to attach the blow off valves so a RIVA Sea-Doo 230/300 Boost Vacuum Port Adapter was bolted on for easy install.

Adding more horsepower, is a RIVA Sea-Doo High Flow Billet Fuel Rail. This component is essential for getting the most out of your fuel system. It replaces the restrictive factory fuel rail for improved fuel delivery. Now we’ll move into the sleek RIVA Sea-Doo RXT/GTX All Rear Exhaust Kit. The RIVA Sea-Doo Exhaust Kit is an outstanding piece of equipment. It is stylish and fits nicely between the water box and hull exit, keeping nasty black streaks off the back of your ski. The kit reduces back pressure for improved performance and has no sound suppression.

For lowering intake temperatures and increasing power, a lightweight RIVA Sea-Doo 300 Valve Cover Heat Shield was installed. A Solas Sea-Doo Concord SXX 13/18 Impeller was added to the Sea-Doo RXT-X 350. The Solas impeller increases low-end thrust and top end speeds on the Sea-Doo 300-horsepower PWC. To improve handling and straight-line stability, RIVA Sea-Doo Pro-Series Sponsons were installed. The rigid fins are fully adjustable, giving you the ability to control the amount of influence they have on the craft.

Speaking of control, RIVA replaced the stock plastic steering system with their strong aluminum unit and topped it off with the RIVA Sea-Doo 30-inch Runabout Bars and capped them with 130mm black ODI Rogue Lock-On Grips. The ODI grips wouldn’t be complete without color matched RIVA ODI Grip End Cap and Clamp Kits.

Also added to the runabout handlebars, were a pair of RIVA Sea-Doo Billet iControl Levers. The aluminum throttle and brake levers are a direct replacement for the stock plastic levers. The levers offer more responsiveness, control, and comfort when racing. This could lead to less finger fatigue.

Another addition to the Sea-Doo RXT-X, is the RIVA Sea-Doo Control Switch Housing Set. The set replaces the bulky OEM control housing. Rounding out the Limited Edition RIVA custom Sea-Doos are the seat covers. The RIVA Sea-Doo Seat Cover is black with the neon yellow stitching for tying it all together.

The Limited Edition Sea-Doos were developed for competition use only and designed for racers who demand the ultimate in power and performance. For additional information on the parts upgrades, check them out on the RIVA Racing website or follow the links provided.
