​​​High Performance Racing Valve Kit for Suzuki® Hayabusa 1999-2014

• The High Performance Racing Valve Kit for the Suzuki Hayabusa is a specially formulated combination of valve materials

   and sizes, designed in conjunction with top racers, for maximum performance.  The kit includes a +1mm oversize

   Tensilite® Titanium Intake Valve and a White Diamond Inconel® Exhaust Valve (standard head size).  Components are

   designed for increased air flow and resistance to the high operating temperatures from applications running forced

   induction and/or exotic fuels.  This combination has been offered as a kit to provide the greatest value for builders and

   racers looking for the ultimate valve setup.


•  All titanium valves
 are 1 piece forged for superior strength over a 2 piece valve.  The Tensilite PVD CrN coating

   is a state of the art process, which is much tougher than the OEM oxiding process.  These +1mm oversized valves offer

   a 33% savings in mass over the ‘99-’07 steel valves and come within 2 grams of the ‘08 and later titanium valves.

•  Inconel® is classified as a “Super Alloy”, meaning that it is designed to survive under the most extreme temperatures

   and pressures, where other valves will begin to burn, corrode, or completely fail.  This is the material of choice for high

   output engines running turbos, superchargers, nitromethane, or nitrous.
