Wiseco Performance Piston KitPart Number: 757M08400Piston Size: 84.00mm These kits contain everything you need to complete your piston repair, the first time Dedicated forgings used for superior strength to weight ratio utilizing aerospace alloy. High Performance ring kit and alloy pin included with each piston kit for extended life and sustained power. Each piston is built from race proven designs that are chosen by the top race teams in all forms of racing including Supercross, Motocross, GNCC, Superbike, and more. All Piston Kits are precision crafted and forged in the USA Wiseco leads the performance aftermarket by producing the highest quality forged pistons for Dirt Bikes, ATV's, Snowmobiles, Outboard Marine, and Motorcycles right here in the USA. Wiseco is unique because we forge all of our own pistons in house, and produce all of our own forge tooling right here in the USA. Extreme racing conditions demand the strength and toughness that only forged pistons can offer. Compared to cast pistons, forgings are tougher and more durable, and will stand up to the abuse that high performance motorsport applications require. Most castings are brittle, have no grain structure and tend to fail catastrophically when the material yield strength is exceeded. Forgings have condensed grain that is aligned to the features of the part, which produces higher mechanical properties, and resistance to impact and fatigue. Each forging is designed to optimize the strength-to-weight ratio, and maximize performance. In addition, in-house dyno testing gives Wiseco the ability to develop state-of-the-art technology such as new shapes, coatings, and components, and lead the industry through rigorous R&D.Fits:2003-05 Yamaha AR2102003-05 Yamaha LX2102003-04 Yamaha LS2101999-04 Yamaha Wave Runner SUV 12001999-02 Yamaha LS20002002 Yamaha LX20002002 Yamaha Wave Runner XLT 12001997-00 Yamaha Wave Runner 7601998-00 Yamaha Wave Runner GP 7601997-99 Yamaha Wave Runner GP 12001998-99 Yamaha Wave Runner XL 7601998 Yamaha Wave Runner XL 12001996-97 Yamaha Wave Blaster 7601996-97 Yamaha Wave Raider 7601996-97 Yamaha Wave Runner II 7601997 Yamaha Wave Venture 7601996 Yamaha Wave Blaster II 760 Standard Piston Size: 84.00mm Bore Oversize: STD Stroke: 68.00mm Product Details Tire Diameter Speed Rating Load Rating Wall Construction Tire Tube Type Rim Size Product Line Wiseco Piston Kit Part Number 757M08400 Fitment Type Unit Sale Qty Each Style Material Color Size 84.00mm Finish Position Functional Length Cable Sleeve Length Cable Sleeve Travel Driver Seat Length Passenger Seat Length Driver Seat Width Passenger Seat Width Piston/Cylinder Size 84.00mm Piston Size Added 0.00mm Cylinder Stroke Volume 68.00mm Final Engine Displacement Exhaust Configuration Muffler Size Muffler End/Tip Style Windshield Height Windshield Width Handlebar Diameter Ca ARB Compliance Non CARB Complaint CARB Compliant Product Disclaimer Items Included Fitments 1999 Yamaha GP1200 WaveRunner GP1200 1998 Yamaha GP1200 WaveRunner GP1200 1997 Yamaha GP1200 WaveRunner GP1200 1997 Yamaha RA760 WaveRaider 760 1996 Yamaha RA760 WaveRaider 760 2004 Yamaha SV1200 WaveRunner SUV1200 2003 Yamaha SV1200 WaveRunner SUV1200 2002 Yamaha SV1200 WaveRunner SUV1200 2001 Yamaha SV1200 WaveRunner SUV1200 2000 Yamaha SV1200 WaveRunner SUV1200 1999 Yamaha SV1200 WaveRunner SUV1200 1997 Yamaha WB760 WaveBlaster 760 1996 Yamaha WB760 WaveBlaster 760 1997 Yamaha WVT1100 WaveVenture 1100 1997 Yamaha WVT760 WaveVenture 760 1998 Yamaha XA1200 WaveRunner XL1200 LTD 1998 Yamaha XL1200 WaveRunner XL1200
