Inside the right saddlebag on the front of the lid where it is angled upwards. In some states that have gates at the toll I velcro it to the outside of the saddlebag guard bag. Even if it doesn't read the tag it is registered to the license plate and no ticket.
Ditto...
Same exact place and it's easily removed to put it in the car too if needed. It's out of the way and doesnt interfere with anything yet very easy access.
Here your lic plate is registered to the EasyPass so even if the pass doesn't work the cameras check the plate against your account and see there's money there and just deduct it. Not a problem. One time my wife drove through in her car (we only have one EasyPass and it's on my bike 99% of the time) without the EasyPass at all and the machine just read the plate and deducted the toll automatically.
in the fairing and to Mike 5959 carry your acct # in your wallet, {mine is on my insurance card} and show it to the authority if E-Z pass does not work
Not sure if it's the same everywhere but in Houston, when I told them it was for a motorcycle, theygave a tag that was specifically for motorcycles. Stronger signal and waterproof. They told me it should read anywhere I put it on the bike. Keep it in the windshield pouch. Also linked to the plate if it doesn't read.
