ZHANGXUE MOTORCYCLES Champion’s Chronicle
WSBK 2026 Season
🏆 Portugal – Double Win
🏆 Hungary – One Win
🏆 Czech Republic – Double Win
🏆 Italy– One Win
Since the start of the WSBK 2026 season, Zhang Xue Motorcycles has claimed six race wins while competing head-to-head with international giants such as Yamaha and Ducati. Zhang Xue’s rise marks the transition of China’s motorcycle industry from “low cost, low quality” to “premium performance, affordable price” – delivering unbeatable value for money. Behind this success lies decades of accumulated strength in China’s motorcycle supply chain, with domestic component manufacturers achieving a global technological edge in precision control, lightweight engineering and independent R&D.
Zhang Xue 820RR – Oil Pump & Regulating Valve
As a precision secondary component inside the engine, the oil pump and regulating valve act as the engine’s “heart valve”. Zhang Xue Motorcycles has developed its own stringent design standards for this critical high-technology part.
Compared with automotive engines, motorcycle engines operate under far more extreme conditions – higher RPMs and wider angle variations – making regulating valve stability essential. During hard track riding or extended high‑RPM operation (e.g. in a high‑revving engine like the Zhang Xue 820RR), the oil pump’s flow rate can become excessive, creating internal drag. Only a precisely tuned pressure relief valve can continuously regulate flow to ensure normal engine function. This represents an unforgiving test of component stability and ultimate performance – the final line of defence against engine overload.
Onboard the Zhang Xue 820RR
In the Portuguese round, when Zhang Xue crossed the line with a 4‑second advantage to take its first win of the season, the 820cc engine was fitted with an oil pressure relief valve custom‑developed by Qingdao Taiyo Giken.
2026 – Congratulations to Zhang Xue Motorcycles, and to us as one of the representatives of China’s manufacturing supply chain – the “hidden champion” powering Zhang Xue’s global campaign.
