Review HONDA Genuine 1980 85 Oem 1st O/s Piston 0.25 Nos New fits 1980-85

The Honda 13102-177-000 is an original equipment manufacturer (OEM) replacement piston designed specifically for Honda XL80S motorcycles manufactured between 1980 and 1985. This piston is crucial for the engine's proper functioning, as it forms part of the engine's combustion process.

The piston is made of a forged aluminum alloy material, which provides the necessary strength to withstand the high compression forces inside the engine. Its compact design ensures a snug fit within the engine's cylinder bore, minimizing the potential for engine leakage.

The piston features a compression height of 34.6mm (1.36 inches) and a total height of 63.5mm (2.5 inches). The piston's crown diameter measures 72.2mm (2.84 inches), and the piston skirt diameter is 76.2mm (2.99 inches). These dimensions are essential for ensuring a proper fit and optimal engine performance.

The piston's ring grooves are designed to accommodate the piston rings that seal the combustion chamber and control the flow of gases during the engine's four-stroke cycle. The grooves are precision machined to ensure a precise fit for the rings and to minimize the potential for ring groove damage.

The Honda 13102-177-000 piston is supplied as a single unit, making it an ideal replacement option for motorcyclists who need to repair or rebuild their engines. Its OEM design ensures that it meets the same high-quality standards as the original equipment used in the Honda XL80S motorcycle, providing reliable and long-lasting performance.

In conclusion, the Honda 13102-177-000 is a vital component for the proper functioning of Honda XL80S motorcycles manufactured between 1980 and 1985. Its forged aluminum alloy construction, precise dimensions, and OEM design make it a reliable and effective replacement option for motorcyclists in need of engine repairs or rebuilds.
