    THE 330 POWERVAVLE MX KIT IS BOLT ON KIT

THE ESR POWER VALVE CYLINDER IS MADE IN THE USA FROM CASTING TO FINAL HAND PORTING.  THE INTRODUCTION OF THE POWER VAVLE INTO THE CYLINDER GIVES THE ENGINE MORE LOW END POWER AND A MORE EVEN TORQUE CURVE THROUGHOUT THE POWERBAND.  THE POWER VALVE WILL GIVE YOU SIGNIFICANT DRIVE OUT OF THE CORNER, OR TOSS A MAJOR ROOST OUT IN THE DUNES.  THE POWER VALVE ACTUALLY CHANGES THE EXHAUST PORT TIMING AS THE ENGINE RPMS INCREASE USING EXHAUST PRESSURE TO RAISE THE POWER VALVE AND OPEN UP THE EXHAUST PORT FOR MAX FLOW AT THE HIGH RPM'S.  YOU CAN FEEL THE DIFFERENCE IN POWER DELIVER VS. THE NON POWER VALVE CYCLINDER THAT HITS HARDER AT THE TOP END WITH LESS BOTTOM END POWER.  THIS IS AN ALL NEW DESIGN OF THE PREVIOUS PRO X CYLINDER AND WE INCREASED THE VALVE TRAVEL IN THE NEW, CURRENT DESIGN FOR BETTER FLOW ON THE TOP END. 

****THIS KIT NOW COMES WITH THE ALL NEW ADJUSTABLE POWER VALVE WICH ENABLES THE RIDER TO MAKE THE VALVE OPEN AT ANY RPM FOR DIFFERENT RIDING CONDITIONS!!!!****

  • RX7 MX/Woods  (Low End)  The ESR TRx7 cylinder is our low-end power option. It exhibits plenty of low-end torque and mid-range power. An excellent choice for MX and Woods riders.
