Well... everyone was right, the standard clear windshield will bolt right up on the 500ri...
-IF- you have the tools, the goo, and know what you're doing. I don't. I ended up with a stripped bolt. One of the 4 the holds the windshield. So, I have 3 of those and the 4 that go through the trim holding the windshield on. Hopefully, it will hold will I drive it up to the shop for them to tell me what I have to buy to fix everything. IF they'll be able to look at the bike.
On a brighter note (yes, there is one)... it does look good on the scoot. Really good.
