Awsome look on my 1997 CBR900RR
My old Katana 1100 came with a pair of these. The chain broke and whipped one them obliterating the lens, but the blinker still worked. I decided to stick with them since they seem pretty durable. They come in pairs so now I have two new ones for less than $20. It took 15 minutes to install both (may vary a little according bike design). I'm thinking about getting a pair for the front. Well made. Inexpensive. Easy to install.
I order from Motosport regularly. Mostly OEM parts to rehabilitate old sport bikes. I've never had a bad experience.
They also give you two mounting options. They come with short screws and you can essential glue them on (wouldn't do that). And longer screw that go through the mounting base (did that).
