Review on Chase Harper USA 1560: Magnetic Mount Tank Bag - Water-Resistant, Tear-Resistant, Industrial Grade Ballistic Nylon with Anti-Scratch Rubberized Bottom - Convenient Magnetic Mounting by Nathan Guzman

The bag is HUGE! Lots of space compared to many 7 liter bags. That's almost up to 30 liters of space! My Triumph Speed Triple doesn't have a metal tank so I went to the trouble of mounting it on the tank and accessing the gas cap. I used old straps from my old bag and attached to 3 points (at the front with the strap provided and 1 attached to the frame on each side). Drive it at freeway speeds and it didn't move with the wind (I think my straps worked!). The tank cap is easily accessible. So far I'm very happy with the multiple compartments, the expandable size, and the incredibly large touchscreen compartment that's also removable! If you need maximum storage space for your motorcycle, this is a great option.
