Tired of soft, easy-to-strip OEM plugs? Upgrade to this premium stainless steel crank shaft plug — a direct-fit replacement for your Hyosung GV125-S EFi (2019–Present). This piece combines strength, precision, and corrosion resistance for riders who want both reliability and subtle custom styling. ✨

- 💪 CNC-machined stainless steel – precision fit, rustproof and long-lasting.
- 🔧 HEX slot design – compatible with socket, hex bit or Allen key, no weird tools needed.
