For the first 35 years of riding motorcycles I thought why the heck use a windshield when bikes are all about feeling the wind on your face. At 65 I still like the feel of wind on my face when I ride my 1975 CB750 café racer. When I rode my Wing from Texas to Alaska a windshield sure was a joy. When I travel I make a backrest out of a touring bag, its nice to lean back for a stretch.
Bottom line, whatever floats your boat.
