This OULI upgraded stator and Kokusan flywheel set addresses common charging and ignition issues in Aprilia’s V4 platform, including weak high-RPM charging, stator overheating burnout, flywheel magnetic decay, and difficult cold starts. The improved stator delivers consistent power output to meet the high electrical demands of the V4 engine, preventing battery drain and sudden stalling during aggressive riding. The Kokusan-spec flywheel maintains stable ignition timing, enhancing cold-start performance and reducing idle instability. Factory-standard mounting dimensions ensure straightforward installation during routine maintenance or engine overhaul. Built to withstand extreme track temperatures and continuous high-speed operation, this kit offers enhanced durability and reliable charging/ignition performance, reducing maintenance frequency and extending the service life of the electrical system for Aprilia RSV4 and Tuono V4 owners.Compatible with ：
