  • The R&D Performance Ride Plate is increased in length over stock and has a steeper rocker section, which will add top speed and eliminate the hunt or bow search noticed in the stock ride plate. Also, smoother and tighter turns can be carved and straight-line stability is significantly increased.

  • The R&D Sponson Kit is a two-stage design and has 3 adjustable positions. The unique blend of a long bullet shaped 6 degree backing plate and a short (GP 1200 R) style sponson blade will significantly improve low and high speed cornering capabilities, and add unmatched straight line stability.

  • The R&D Power Plenum Breather Kits unique design will flow much more air than the O.E.M. filter. O.E.M. filters are notorious for becoming over oil saturated causing sluggish low-end power and a loss of up to 500 RPMs! The R&D replacement breather will never become over oil saturated, making it the only replacement choice! Easy to install in 5 minutes, adds a great sound tone, and adds RPMs.

  • The R&D Pump Shoe sealer kit will seal up the FX-140ís pump shoe and pump inlet to promote reduced cavitation, much better hook-up, and add top speed performance.

  • The R&D Yamaha FX-140 Aquavein Intake Grate has been in design, development, and testing stages for two years. The R&D FX-140 Aquavein will significantly reduce cavitation, increase acceleration, add up to 1 mph on top end performance, and keep the FX-140 pump loaded and hooked up! Works great on after market supercharged models as well.

  • The R&D Solas FX-140 12/18 Concord is a great replacement impeller over stock. Increased acceleration and up to 1 mph in speed performance gain.
