I also had a Goldwing prior to the Trophy. The Goldwing engine is silent in comparison to the Trophy. Don't be alarmed with the noise; a decent helmet, or earplugs will be necessary for noise control. The 2015 models do not have the problem that you describe. My 2014 has plenty of driveline gear noise, and engine noise. I've been assured that it's normal and gives character to the Trophy.
