 RIVA STX-15F Endurance Engine Kit

Stock 61 MPH @ 7,600RPM
Endurance Race Unit * 70+ MPH @ 8,100RPM
* = With required & optional performance parts.
 
NOTE: All testing was performed with 1/3 tank of fuel and trim in neutral position.  
 
Our Endurance Engine Kit for the Kawasaki STX-15F contains the same components and specifications that Team Kawasaki developed to dominate the international racing circuit. This modification produces excellent acceleration and a top speed of over 70mph using VP MS109 race fuel (Jet X).

High compression racing pistons are installed along with performance intake & exhaust camshafts. Fuel delivery, engine timing and rev limit are optimized to match the increased demands of the modified engine via a race programmed Mitsubishi ECU that plugs directly into factory wiring harness. Kit includes all necessary gaskets and detailed installation instructions. We highly recommend use of our Performance Power Filter (part# RX13085) with this package.
