I saw a picture of motorcycle bars on a Spyder and I thought I saw some for sale with a top piece that bolts on. I don't know who sell them. The little that I saw shows the top cover off and then any correct diameter bar can be used. Not sure about the ignition switch. Are these bars for sale? Is there a video that shows how to do this? I need to try different bars and this looks like a good way to go. thanks
