I've tried mounting my e-ZPass everywhere. On my last bike, I mounted to the windscreen. That worked pretty well. I've tried in my pocket, on my sleeve, in a tank bag. It's all very hit or miss. The only problem of mounting on the bike is that it can be stolen, unless you really bolt it down or remove it anytime you park. The fairing would solve this problem: it would be hidden from view and the fairing isn't even as dense as windshield glass. I've got a 50/50 feeling about it. So, I'm going to velcro it in and give it a test in the next week. So, I'm wondering if anyone else has tried mounting the transponder behind a front fairing? Any luck or opinions?
