High Performance Spring Only kit and OEM Replacement Retainers for Kawasaki® ZX-14 2006-2011
• Spring Only Kit, 40-40292 is compatible with OEM Retainers & Basewashers and can be ordered individually, however KPMI® reccomends the 40-40291 Retainer for increased durability over the OEM.
• This retainer,40-40291 is thoroughly a product of modern engineering. KPMI® engineers spent nearly a year studying
materials and surface treatments to find the ideal balance of hardness, toughness, wear resisitance, and strength. They
spent countless hours refining the design with finite element analysis and the results are impressive. These efforts led to
the new KPMI® retainers being more than 83 grams lighter than OEM per set of 16 retainers!

By utilizing FEA software and a special blend of heat treated alloy steel, it was possible to reduce mass while maintaining strength and wear resistance. These retainers are intended as an OEM replacement and are completely compatible with the OEM springs, keepers, and basewashers. The spring shoulder diameter has been designed to match the OEM retainer and spring as well as KPMI's high performance spring (P/N 91-91051), making this retainer your high performance OEM alternative.

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
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.
