This Saddleman wide tail bag is a missing link for me. It is a perfect carrier for the ZX-14, fitting the saddle to a Tee.I have a 60 mile commute in the Texas summer, and am able to put slacks, shirt and shoes, as well as gym clothes and a small case with pens, micro sd, moleskine, etc. in for the run. I can also drop in a thin 15" laptop when needed.The attachment is very smart: simple to install, effective and unobtrusive when not needed.I have been looking for just such a bag for a very long time. Backpacks are unpleasant in the summer heat, and other tailbags are a nuisance to mount and dismount. This one is simply well-conceived and nicely executed.That said, I am not overwhelmed by some of the material choices and am a little curious about how long the bottom fabric will last. The securing straps for the seat mount are adequate, but not robust. I've supplemented them with a 3rd high strength anchor strap.All considered, I recommend the Saddleman tunnel bag for you sport bike monkeys. It has not flown off in triple Ds and holds a bunch of kit. I will definitely update this if I find otherwise... Go On!
