I just received the Yamaha branded tank bag for the R3. It's big enough to carry an extra pair of eye glasses and a tube of Chapstick. I wear a prescription so its nice to have a clear pair when I'm wearing the sunglasses in case I'm out after dark. The clear case portion fits my iPhone 6 in a Lifeproof case just fine. I have the Garmin nav app on my phone so that's handy. There are several suction cups for fastening and a safety strap you wrap around the frame for added security. Best of all no removal necessary when getting gas.
