💎 FUNCTIONAL BLING // MAGNETIC PROTECTION // EASY OIL CHANGES!

More than just a pretty cap. Stop metal shavings from traveling through your motor. The stock filler cap does the job but offers zero protection, making a fresh Hyosung magnetic oil cap upgrade the smartest way to grab floating metal debris inside your clutch cover during your next maintenance oil change project.

  • Engine Health // A powerful built-in magnetic core traps floating steel clutch and gear shavings that the main filter might miss.
  • Workshop Friendly // Robust hex head shape replaces the awkward original tab so you can turn it with a standard spanner.
  • Anodized Finish // Machined from solid aluminum with a corrosion-proof color layer that survives brutal winter downpours.
  • In Stock // Ready for your next oil change. Pick your color option from the dropdown menu to upgrade your casing looks instantly.
⚠️ CRITICAL FITMENT MATCH: Fits the following models only: GV125 Aquila (pre-2017) and GT125/R (pre-2019) carburettor twins.

❌ Will NOT fit 250cc or 650cc engines.
❌ Will NOT fit 2018-onwards GV125S EFi Bobber models.

Description

The factory oil plug sits directly on the right-side clutch housing, serving as the main entry port where you pour fresh lubricant into the case. The standard original part is a flat piece utilizing an awkward, slotted ridge design that forces you to squeeze a pair of pliers onto the tab just to crack it open. This premium aftermarket Hyosung magnetic oil cap upgrade replaces that weak setup with a beautiful, hex-shaped billet aluminum bolt that unhinges easily with a regular workshop spanner. More importantly, it features an integrated high-strength magnetic tip extending directly into the engine oil passages. As your bike handles touring, daily riding, or long road trips, the core actively captures floating steel shavings shed by normal clutch plate friction and gear mesh. Trapping these metal bits takes the load off your filtration paper, ensuring your oil stays clean across your latest restoration project.

🔧 Installation Tips & Maintenance Guides

Installing this anodized cap is a simple, direct swap on your workbench. Follow these pro pointers to keep your engine safe:

  • Scrub the Neck Casing Clean: Use a clean cloth to thoroughly wipe down the area around the filler opening before unbolting your old cap. This stops grit from dropping inside your open clutch housing.
  • Pre-Lubricate Your Rubber Ring Seals: Smear a tiny film of fresh motor oil directly onto the O-ring before threading the plug into place. Lubricating the rubber ensures a plush seal and stops it from pinching or tearing.
  • Check the Magnetic Core for Debris: Every time you pull the plug to top up fluids, look over the tip. Fine gray metal dust is normal wear, but finding large chunks means you need to look closer at your internals.
  • Hand-Tighten Firmly Only: Screw the bolt down manually using your fingers first. Billet aluminum threads easily strip out soft engine covers if you over-tighten them with brutal tool force. A gentle nudge with a spanner is all it takes to lock it.

📧 NOT SURE IF YOUR COVER USES THE SAME THREAD PITCH SHAPE NATIVELY?
