Description

On the road, original factory chains often feel “tight” or “buzzy” at high speeds. This isn’t just a maintenance part; it is a definitive mechanical upgrade. By combining high-grade Japanese/EU steel with our unique “Fast Ratio” rear sprocket, we eliminate the vibration and high-rev stress that usually limits the GV300S. Whether you’re commuting or touring, your engine will finally feel like it’s breathing.


💎 Ride Faster with X-Ring Efficiency & Better Sprockets!

Our bespoke gearing setup is designed to give you more “legs” on the open road without sacrificing off-the-line acceleration.

Premium X-Ring
Lower friction than O-Rings for maximum power delivery.
Touring Comfort
Lower RPMs at 70mph means less vibration through the pegs.
Bespoke Gearing
Exclusive HyoRiders ratios not found elsewhere online.
Stainless Fixings
High-contrast hardware that won’t rust or seize.

🔧 Install Tips

  • Direct Swap: This is a “Bolt-on” kit. No modifications to your swingarm are required.
  • Safety First: Always use the included safety lock washer on the front sprocket to prevent nut loosening.
  • Chain Care: While X-Rings are ultra-durable, a clean chain is a fast chain. Use high-quality lube every 300-500 miles.

  1. Erick

    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.
