Welcome. Search for many posts on the subject.
I installed larger tires, an Aftermarket Assassins cruiser kit as well as sound deadening everywhere. It's tolerable now but never gonna be as good as your truck or car
I’ve done a clutch kit, ECU tune, sound deadening, and bigger tires. Significantly quieter at higher speeds, but like John said, will never be that quiet. Suggestions riding alone use noise cancelling headphones, with others… crank the music and drown out the engine. Ha.
We opted for the Cardo Packtalk Edge headsets, quiets noise and we can talk normally and each can listen to thier own music which gets interrupted when someone talks. Ours are crystal clear and wireless
