Swingarm: Restores handling and suspension control due to worn or rusted swingarm components. Complete kits contain bearings, pins, collars, and seals manufactured to O.E.M. specifications for a perfect fit. Considerable savings over O.E.M. pricing. All components for rebuild. Shock: Kits include two Teflon spherical bearings (cup bearings when used), four seals and related components. All shock kits rebuild both ends of the shock absorber. Note: Some shock absorbers on Kawasaki and Honda models use a clevis to connect the shock to the linkage. The bearings, collars and seals which are pressed into the linkage arm are included in the kits. Linkage: Restores handling and suspension control due to worn or rusted linkage components. Complete kits contain bearings, pins, collars, and seals manufactured to O.E.M. specifications for a perfect fit. Considerable savings over O.E.M. pricing. Complete kit for suspension bearing replacement. Note:All parts are backed by a lifetime replacement offer.
"I decided to tear apart my suspension soon after I purchased my 2003 YZ250 to re-grease the suspension. Later investigation revealed the suspension bearings were all dry, dirty grease with broken needle bearings, etc... Pivot works bearings hooked me right up. The bearings were installed using a press and numerous sockets, and a few jigs. time consuming but was happy with the end results, Suspension feels great!"
The MotoSport.com Wiseco Pro-Lite Piston Kit - 2-Stroke includes one of each of the following components with the following attributes: The Wiseco Piston Kit is not just a basic piston replacement, it is a performance piston kit that is more durable than O.E.M. pistons and includes everything necessary to rebuild your top end. Wiseco Pro-Lite Piston: Important note: This piston is for a stock sized bore. Please measure your cylinder to check clearance before ordering. Wiseco leads the performance aftermarket by producing the highest quality forged pistons in the U.S.A. Wiseco is unique because they forge all of their own pistons in-house, and produce all of their own forge tooling in the U.S.A. This allows Wiseco to control all aspects of their manufacturing process from raw bar to skirt coating on the finished parts. Wiseco Pro-Lite motorcycle pistons are forged using the highest quality materials available resulting in a piston that provides excellent performance and durability. The Wiseco Pro-Lite piston features a race-ready dome finish with smooth edges for improved combustion flow. The rings, wrist pin, and circlips are manufactured by Wiseco under their strict quality standards to make sure every piston kit fits correctly, ensuring top performance is achieved. Pro-Lite Piston features: Much stronger than stock. Tight tolerances for quiet running. More hours with peak performance between piston changes. All Pro-Lite pistons include rings, wrist pin and circlips. 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. Wiseco Needle Bearing: The Wiseco Needle Bearing is a high quality replacement wrist pin bearing designed to withstand the harsh demands of racing. Wiseco built their needle bearing to meet or exceed O.E.M. specifications. Cometic Top End Gasket Kit: State-of-the-art gaskets is what Cometic has been doing since its inception in 1989.

"2003 YZ250, Wiseco piston felt lighter and better made than oem, I did not have to file the rings as they were right in spec out of the box. The old oem piston had a small hairline crack did not even know, luckily I just decided to rebuild the top end as a safety precaution, forged pistons are a lot tougher. Top end kit thats included comes with every gasket and o-ring that goes on the head."
