The stock one make good garage art. I went from stock mounted all the way up to a 7Jurock dual headlamp, Classic, 16 inch, clear, standard shape, mounted all the way down. Measure from the center bolt to the top of the shield. 188$ delivered. Made a very big difference. If you are used to riding behind the shield, they make it higher. When it gets damaged I'll buy another one. No matter how careful you are they will scratch.
I am 5/11 and can see over the shield if I sit up straight and still keep the helmet in clean air. If I'm going fast over 75/80+ I lean forward and get closer to the shield.
If it had to be higher I can just raise it some. If I'm going to be going slow, 50/60 mph, I just take it off. Truly, this is the cleanest air, just make sure you cover your skull and face.
In my opinion the plastic on the 7Jurock is clearer and thicker but both brands are very good products. 7Jurock ships it fast.
