Description

On the road, original factory chains often feel busy or cause noticeable feedback at high speeds. This isn’t just a basic maintenance part; it is a solid mechanical upgrade. By combining high-grade steel with our unique gearing ratio on the rear sprocket, we reduce the vibration and high-rev stress that usually limits the GV300S. Whether you are commuting or touring, your engine will finally feel much more settled during everyday travel.

🔧 Install Tips

  • Direct Swap: This works as a straightforward bolt-on installation with no modifications needed on your factory swingarm guard.
  • Safety First: Ensure you fold the tabs over on the fresh lock washer included in the package to secure the front drive sprocket nut.
  • Chain Care: While sealed X-ring configurations retain internal grease well, keeping the exterior rollers free from road muck every few hundred miles prolongs component lifespan.

    After installing this kit, my 300 can really cruise through every gear without screaming through the ram’s. This bike is immensely more enjoyable to ride now and I often leave my iron 883 at home to take the aquila out for a ride.

    If you only do one thing to your Aquila 300, install this kit. I promise you won’t regret it.

    Great parts, great service.
