R&D Yamaha GP 1800 / FZ / FX / VX / VXR / VXS “Race Fin” Sponson kit

The R&D Yamaha GP 1800/FZ/FX/VX Sponson Kit was developed to deliver improved handling stability
and much smoother top speed performance in recreational, offshore, and closed course race conditions.
The kit also reduces Chine walk in hard 90° and 180° turns, and is super stable at high top speeds!

The R&D sponson kit is a unique design that adapts an additional “Deeper Race Fin” blade that
assembles and mates between the oem sponson and the hull. The “Race Fin” has proven to outperform
all other sponson kits on the GP1800! Race Proven in closed course with multiple wins in regional and
World Finals competition, as well as Dominating and winning the 2018 Mark Hahn 300 on the 85+ MPH
R&D Turbo Machine of Mike Klippenstein!
