Description

Tiny metal flakes are a hidden issue for high-revving engines. While your main oil filter cartridge catches the big grit bits, this magnetic sump bolt pulls in the incredibly fine metal dust that floats around inside your engine casing. By locking these shavings down at the lowest point of the oil pan, you stop them from scraping your internal bearings or blocking your oil pump lines. It is one of the cheapest and most effective upgrades you can give your GV300S to enjoy absolute peace of mind on everyday roads.

💎 MOTOR INTEGRITY HARDWARE SPECIFICATIONS

Tough Bolt HeadStronger hex flats give your spanner or socket a much better grip during services. Anodised AluminiumLightweight metal that will not seize or corrode into the main engine casing thread.

📜 Confirmed Fitment Guide

Modern Liquid-Cooled 300cc Group: Fits the lower engine sump pans on the fuel-injected bobber and sport models listed below.

  • Hyosung GV300S Aquila Bobber EFi: Fits all standard models from 2020 to present date.
  • Hyosung GV300SS Aquila Supreme Spoke: Fits all modern cruiser variations from 2020 onwards.
❌ WILL NOT FIT THESE MOTORCYCLES:

  • Older Generation 125 / 250 / 650 Models: This sump bolt thread matches the modern 300cc case layout only. It will not fit classic air-cooled bikes like the GV125, GV250, or older GT naked and sport lines.
💡 SERVICE BUNDLE SUGGESTION: Don’t forget to swap your oil filter cartridge at the same time you drop your oil. Fresh engine oil deserves a clean filter element to ensure optimal oil pressure and flow! View GV300S Oil Filters here.

🔧 Install Tips

  • Do Not Overtighten: Aluminium sump bolts need a careful, steady hand. Always use a proper torque wrench and tighten the bolt to the factory setting (usually around 20-25Nm) to avoid pulling the threads out of your soft engine cases.
  • Clean the Magnet Tip: Every time you do an oil service change, use a clean garage cloth to wipe off the magnet. You will notice a small bit of dark metallic fuzz stuck to it—this is exactly what you are saving your motor from!
  • No Liquid Sealants: Do not use thread-locking glue or silicone liquid gaskets on the bolt threads. The included aluminum or copper sealing washer is designed to sit flat and stop leaks all by itself.
