I think you are on the right path then mate.
There are good helmets for it too... An open face I bought recently blocks way more exhaust noise than my full face.
Didnt notice when I tried it on in the shop, but on the first ride it was obviously quieter than any helmet I have had before. Biggest difference for start to the work day.
Bonus that it wasnt too dear (think it was $80 cash at a harley stealer) and was matte black.

Hey Jye, I have a set of SE Black Slip Ons and Buckshot shields if you are keen? Also have an SE Air Filter if you want to add it to your beast.
