Recently, the World Superbike Championship (WSBK) has come to a successful conclusion. Chinese racing bike Zhang Xue 820RR-RS claimed two championships, marking a historic breakthrough for Chinese motorcycle brands in this world-class event. The core component powering this championship-winning racing vehicle is the piston pin independently developed and manufactured by Shandong Liaocheng Derun Electromechanical Technology Development Co., Ltd., fully demonstrating the solid strength of "Liaocheng Manufacturing".

As a top-tier global motorcycle racing event, WSBK sets extremely stringent standards for component performance. During high-speed races, the piston inside the engine reciprocates tens of thousands of times per minute. Serving as the key core part connecting the piston and connecting rod, the piston pin directly determines the power output and operational stability of the racing motorcycle. The championship-winning piston pin is jointly developed by Derun Electromechanical and Zhang Xue Motorcycle, representing a core achievement of their in-depth strategic cooperation.

Derun Electromechanical is not only an official piston pin supplier but also the designated signed supplier (No. E0001) of Zhang Xue Motorcycle, with their partnership dating back to the establishment of the brand. Drawing on nearly 30 years of professional experience in piston pin design and manufacturing, the two parties conducted in-depth technical coordination starting from the initial product design phase.

This racing-specific piston pin is made of high-grade special steel with advanced surface treatment technology. Manufactured under micron-level high-precision standards, it perfectly adapts to extreme working conditions of racing bikes featuring high rotating speed, high explosion pressure and strong impact force, providing reliable core power support for the championship victory.
