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 thus kit. I promise you won’t regret it.
Great parts, great service.
