Gallery: RIVA Racing’s Limited Edition 2020 Yamaha GP1800R


We may be living during uncertain times but that hasn’t stopped RIVA Racing from developing ten bad powerful Yamaha GP1800R SVHO  in an eye-scorching blue and yellow livery, complete with a host of RIVA performance products. We wouldn’t expect anything less because, after all, RIVA Racing were the first to develop a line of Limited Edition series PWC. The team is continuing the tradition in 2020, by upgrading the Yamaha GP1800R SVHO with perfectly matching RIVA Racing parts.

Each machine is outfitted with exclusive hull graphics and black anodized components. When looking under the freshly recovered black and blue stitch RIVA GP1800R Seat Cover, you’re greeted with a powder coated red valve cover equipped with an engraved one-of-a-kind production number plate. The plates are numbered from 1 to 10, so you know you’re on a truly limited-edition machine. Claim it!

 

The engine puts out a hefty 350-horsepower with face-peeling acceleration and a blistering top speed of 86mph on 93 pump gas. Of course, RIVA includes upgraded steering and handling components to ensure that the rider has complete control while hauling ass. This bad boy is race ready with plenty of muscle for the track or a buoy course. So without further ado, let’s delve into the components that make RIVA Racing’s Yamaha GP1800R SVHO an exceptional machine.

It begins with the RIVA MaptunerX Yamaha License. This is what is used to unlock the engine’s potential and elevate the speed of the watercraft so the rider can really turn it up. Next, RIVA adds even more power by upgrading the fuel system with a RIVA Yamaha 1.8 High Flow Billet Fuel Rail. It is used to not only add horsepower, it’s also there to support the fuel system due to increased horsepower from the supercharged PWC. The stock fuel system is too restrictive to handle the upgrades.

Speaking of “too restrictive,” RIVA replaced the stock air box with their own Yamaha GP1800R SVHO supercharged power filter kit. The Power Filter continuously feeds the supercharged engine a flow of cool air, which leads to significantly improved acceleration and rpm. The machine is then fitted with an easy-to-install RIVA Yamaha 1.8L Engine Breather Kit. This increases horsepower by removing the engine’s requirement to burn relatively non-combustible oil. It also prevents oil from coating the intercooler that lowers thermal efficiency.

In order to maximize lubrication and to limit wear and tear on the stock shaft, RIVA replaced it with their Yamaha Supercharger Shaft Upgrade Kit. During all the smoking hot riding time, the engine has to have some chill and that’s why RIVA upgraded the limited edition PWC with the new Gen-3 Yamaha SVO/SHVO Power Cooler Kit.. The intercooler system provides exit temperatures 50F cooler than stock, which is much needed on the Yamaha GP 1800 SVHO.

The crew added the RIVA 2020 Yamaha SVHO Pro-Series Engine Cooling Upgrade Kit to further maintain proper temperatures for increased reliability and performance. Also, a RIVA Yamaha Valve Retainer Upgrade Kit is added to reduce the possibility of valve float at high rpm. The addition of the RIVA Yamaha GP1800 VXR/VXS Rear Exhaust Kit frees up the SVHO’s ability to evacuate spent gases while giving the ski a cacophonous roar when screaming across the water.

The through-hull exhaust kit replaces the factory plastic components with solid aluminum tubing. Less clamps are required for the new set up too, making it easier to access other components inside the machine. The blue anodized exhaust opening looks sharp and keeps the filthy exhaust off the transom due to its new placement away from the pump.

A Solas Yamaha 160MM Concord 13/18 Impeller was added to harness any speed that may try to escape. The large blades take care of business! The RIVA Yamaha Gen 2 GP1800/VXR/VXS Top-Loader Intake Grate was also installed for the ultimate in speed and traction. Helping to keep the watercraft from cavitating while running at high speeds, is the RIVA Yamaha Gen 2 GP1800/VXR/VXS Pump Seal Kit, a necessary part to keep the craft moving without any hiccups.

Adding to stability and responsiveness are the RIVA Yamaha GP1800 FX/VXR/S Pro-Series Sponsons. These will enable a racer to hold a tight line or make the tightest turns while staying glued to the water at optimum speeds. Moving to the top, we meet the steering assembly. It’s comprised of the RIVA Yamaha GP1800/VXR/VXS Pro-Series Steering System, RIVA Pro-Bar 32” Runabout Bars, and rounded out with a RIVA Yamaha RIDE Throttle Housing Cover Plate. The stock grips were replaced with ODI Rogue Lock-On Grips and end-capped with ODI Grip-RIVA Caps.

The 2020 RIVA GP1800R SVHO Limited Edition will cost you $27,995 – and was built with riders who demand the ultimate in power and performance. It is not a PWC for the weekend warrior. The ten Limited Edition units are offered through RIVA Racing, a division of RIVA Motorsports. For more information or to order, contact RIVA at info@rivaracing.com or call (954) 785-2684.

    Anyone test the new Riva intercooler over (say) the Fizzle or new WORX for the 1800? I doubt it seriously.
    I want to add that, unlike so many other of these companies who try to sell you their parts, RIVA has a real PHONE NUMBER you can call and actually DISCUSS your needs and questions. Good for you, RIVA! Try that with some others!

      I always find it important that a company STAND by its name and product. I’m glad you feel the same. No, we haven’t conducted any sort of thermal efficiency testing on all 3 intercoolers.

    Having worked as an outside contractor for NASA, we have the means to test these intercoolers for both thermal efficiency and back-pressure. But no company would dare send theirs for such a comparo. Much easier to use phrases like “awesome gains” and such rather than wanting to deal with quantitative results.
