A PCer on the Facebook PC800 group sent me a couple photos of this windshield edging. I am told that the edging helps to reduce helmet buffeting.
I believe this is an OEM Honda tall windshield. I believe Clark Rice on the FB group sent me these photos. Or at least he identified the material: Micro-Swirl Gen-4 Edging. I’ve only seen it on this one PC but the reports are good.
