If you’ve spent any time on a Yamaha SVHO-powered machine, you already know the potential is there. Whether it’s the long-legged stability of the FX platform or the razor-sharp aggression of the GP, the factory setup is just the starting point. And right now, RIVA Racing is making a strong push with a full lineup of upgrades aimed squarely at unlocking what these supercharged 1.8L and 1.9L engines are really capable of.
At the heart of it all is boost—and RIVA’s newest supercharger impellers are designed to take full advantage.
The new R3 Supercharger Impeller is positioned as a serious step up from stock, with a redesigned blade profile that increases airflow and boost pressure across the entire RPM range. The result? Stronger acceleration, harder mid-range pull, and more top-end speed—all from a component that drops into the factory housing. At $499.95, it’s one of those upgrades that punches well above its weight in terms of performance per dollar.
Looking for more? The R4 Supercharger Impeller takes things even further. With an even more aggressive design, it’s built for riders chasing maximum output from their SVHO platform, delivering higher boost and more airflow for $599.95. Both are precision-machined from billet aluminum and anodized for durability—important when you’re spinning at those kinds of RPMs.
Of course, more boost means more heat—and that’s where RIVA’s cooling upgrades come into play.
Their GEN-3 Power Cooler Kits are built around a massive intercooler core rated for up to 600 horsepower. That’s not just overkill—it’s headroom. By dropping intake air temperatures by an average of 50°F compared to stock, these systems deliver cooler, denser air, translating into more consistent power throughout the rev range. RIVA claims gains of up to 20 peak horsepower over the OEM intercooler, along with improved reliability thanks to an integrated 50mm TiAL blow-off valve.
Available across multiple SVHO platforms—including 2019+ FX models, GP1800R variants, and earlier FX/FZR/FZS applications—each kit comes in at $1099.95 and includes everything needed for installation.
Handling and control haven’t been overlooked either.
RIVA’s Pro-Series Steering Systems for both the 2022+ FX and 2021+ GP platforms bring a more connected, race-inspired feel to the helm. At $699.95, these setups are aimed at riders who want more precision and confidence when pushing harder in rough water or aggressive cornering situations.
On the exhaust side, the Pro-Series Waterbox is another key piece of the puzzle. Designed to improve exhaust flow while maintaining durability, it features radiused tubing and a unique internal baffle that boosts low-end and mid-range performance. On modified engines, RIVA reports gains of up to 15 horsepower—along with the kind of torque increase you feel immediately when you squeeze the throttle. At $489.95, it’s a solid supporting upgrade for anyone building out a more complete performance package.
As always, orders over $150 ship free within the continental U.S., which takes a little bit of the sting out of stacking multiple upgrades in the cart.
For riders looking to push their Yamaha FX or GP SVHO beyond factory limits, the path is pretty clearly laid out.
