The part number for the trim is 58706-98C. The cost is around $20.
The Clearview windshield is no doubt better form a function perspective. It takes forever to custom order them, but when you get it the quality is exceptional. They stand behind their products as well. As long as you leave the plastic protector on you can return it no questions asked. CV also protects the rider form wind, noise, etc. better than anything else I've found.
The cool factor is also important on a sex machine like a SERG. Looking at it as form, not function, perspective Klock Werks has cool dialed in. Their shields look great on the bike and work reasonably well. Many people complain about wind hitting riders in the face, noise, etc., but KW is unique and every bike that has one gets attention. That said, however, KW is not perfect. Their shipping department is a joke, when you call them the people are not customer-focused or knowledgeable about their own products and they don't ship complete kits with trim and parts needed. Personally, I'd rather pay a few more bucks and have the shield boxed properly and get a trim kit.
