Wiseco Wrist Pin for Yamaha (S277)

The Wiseco S277 Wrist Pin is designed for Yamaha applications requiring dependable piston and connecting rod performance. Manufactured using Wiseco’s high-tech production processes, this wrist pin provides greater operating strength and controlled expansion during high-temperature engine operation. Its precision-focused construction supports reliable movement between the piston and connecting rod, helping maintain consistent performance in demanding powersports environments.
Wiseco’s engineering expertise is reflected in the S277’s ability to withstand the stresses associated with high-rpm operation and elevated combustion temperatures.
