💎 STAINLESS CRANK PLUG | HEAVY-DUTY FLYWHEEL CAP UPGRADE

Bin that “cheese-metal” OEM plug. This solid, weighted Stainless Steel replacement is significantly more robust than the flimsy stock part, providing a reliable, multi-tool access point you can trust during engine maintenance.

✅ Beefy Build: More material weight means it won’t strip or round off like the original.
🛠️ Multi-Tool Drive: Use a socket, hex bit, or large Allen key to turn the engine over with ease.
⚙️ CNC Stainless: Corrosion-proof, weather-resistant, and less likely to seize than the stock cap.
📦 What’s Included: 1x Heavy-Duty Crank Plug + Fresh O-Ring Seal.

💡 INSTALL TIP: Perfect for accessing the flywheel to perform critical valve clearance checks. View the video in the picture gallery to see it in action! 🖼️📺

Description

Every mechanic in the UK and EU knows the struggle with the stock Hyosung crank plug: it’s made from a soft material with an awkward single “slit” that rounds off easily when seized. This unique creation is a serious performance upgrade. Our own testing proved that the added weight and superior material prevent the common issues, making your life on the road and maintenance schedule much simpler.

💎 The Visual & Performance Upgrade That Lasts

We solved the common “stuck plug” nightmare using solid stainless steel and superior CNC machining.

Corrosion Free Salt-resistant for harsh winter riding conditions.	Robust Design More ‘meat’ around the tool opening; won’t strip.
Easy Access Use common workshop tools instead of a mystery key.	CNC Precision Perfect thread fitment every time.
