Thanks

I agree with Mike....it all depends on what looks and functionality you are looking for ...sport, tour, both. Small handlebar or larger bike mounted.
Way back in the day I mounted a replica 1980 Suzuki GS1000s fairing. I liked the looks and it did block airflow on the chest. It also effected handling at max rpm in 5th! I took it off, trimmed the back fiberglass quite a bit so it would fit on my white Goldwing 1975 Endurance Racer

....see photo of it and lots more fairings in the thread and pix posted in the link below
Here is a link to lots of early models with fairings.......
