Introducing the WiseCO 557P4 NOS Piston Kit for 1987 Suzuki RM125, RM125 Pro-Lite motorcycles. This high-performance piston kit is engineered to deliver enhanced power, improved efficiency, and extended durability for your Suzuki two-stroke engine.

The WiseCO 557P4 piston kit is designed specifically for the 1987 Suzuki RM125 and RM125 Pro-Lite models. It is an over-square piston kit, meaning the piston diameter is slightly larger than the bore diameter, which helps to increase the engine's compression ratio and power output. The piston kit comes with a piston diameter of 55.00mm and a stroke length of 1.00 inches.

Each piston is precision-machined from high-quality aluminum alloy to ensure a perfect fit and optimal engine performance. The piston crown features a unique design with a raised dish to improve combustion efficiency and power output. The piston skirt is designed to provide a snug fit in the cylinder bore, ensuring optimal compression and reducing engine blowby.

The WiseCO 557P4 piston kit also includes a set of rings, including a compression ring, an oil control ring, and a skirt oil scraper ring. These rings are designed to provide a perfect seal between the piston and cylinder wall, ensuring efficient combustion and minimal oil consumption.

The piston pins are made from high-strength steel and are precision-machined to ensure a perfect fit in the piston and crankshaft. The piston pin bushings are included in the kit to ensure a smooth piston pin operation and reduce wear on the engine components.

This piston kit is an excellent upgrade for riders looking to extract maximum performance from their Suzuki RM125 or RM125 Pro-Lite motorcycle. It is easy to install, and the included instructions make the process straightforward. With the WiseCO 557P4 piston kit, you can expect improved engine power, increased efficiency, and extended engine life.
