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.

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.
