The Riva Stage 1 PLUS Kit delivers a huge performance gain with simple bolt-on modifications! Expect awesome acceleration and a top speed increase of 14 MPH.

RIVA TESTED: 82 MPH @ 8,100 RPM

Includes:

1) Maptuner X programmer is utilized to reflash your original ECU (Engine Control Unit) for added performance.

The MaptunerX Bundle delivers instant plug-in horsepower! Quickly and easily load our Stage 1 performance tune into your Yamaha ECU eliminating the need to ship out your ECU for programming. Features a slick, full color, touch screen display. There is no limit to the number of vehicles or tunes you can reflash with the MaptunerX. Simply purchase one additional tuning license for each vehicle that you would like to program. The MaptunerX features a slick, full color, touch screen display for east operation. Includes full access to RIVA's World Famous Tuning Library along with unmatched technical support. Easily switch between performance tunes and then back to stock settings if you wish.

Maptuner X Features and Benefits:

  • Awesome acceleration and a top speed increase of 9 MPH!
  • Reflash your ECU instantly without shipping it out for programming.
  • Switch between performance tunes quickly & easily.
  • Restore stock tune settings if you wish.
  • Easy to use, full color, touch screen display.

2) RIVA GP1800 Performance Power Filter is installed. Kit replaces restrictive factory intake system delivering improved throttle response and top-speed.

3) RIVA Intake Manifold Upgrade Kit is installed. Precision tapered billet sleeve directly replaces restrictive mesh element in intake manifold enabling engine to produce more horsepower through increased air flow and boost pressure (+1PSI).

4) RIVA Stage 1 Engine Cooling Upgrade Kit is installed. Kit improves water flow to Yamaha SVHO engine and intercooler for improved performance & reliability. Greatly reduces loss of power due to "heat fade" on stock and Stage 1 modified craft.

5) Solas Concord Impeller is installed. New design incorporates a large blade area and superior hub design that deliver increased acceleration and top speed. Billet nose cone included.

Note: We also offer Solas 13/18 pitch impeller (YV-CD-13/18) that produces approximately 300 more RPM than 13/20 pitch impeller (YV-CD-13/20). Although target RPM for this kit is 8100, RPM is often reduced by high altitude operation or extreme ambient heat and humidity. 13/18 impeller can be utilized to achieve target RPM under these extreme conditions.

6) RIVA GP1800 Performance Ride Plate is installed. Our ride plate increases top speed and significantly enhances handling characteristics.
