short version: list your bike plate on your I-Pass account, then forget it even exists.
I went into extreme detail with the people at I-Pass a while back. The final word I got was "I-Pass isn't guaranteed to work with motorcycles, so we cannot issue one for your bike. What we recommend is to register your motorcycle license plate onto an existing account, such as your car. If for some reason the automated system doesn't register the transponder while you're riding, the backup system will send you a request for payment."
My bike's been registered since I got it... so far, I haven't gotten a single bill. I have gotten a few for my car though. I do keep my I-Pass account number with me though, in case a cop pulls me over (which I don't even know if they do any more).
I also firmly believe that the risk of putting my foot down in a pool of oil at a tollbooth is unacceptable, and would flat out refuse to pay if that was my only option. I'd love to be able to take that case to court as well, but they always drop it as soon as it becomes non-profitable.
