Before ordering I probably should have found a box with similar measurements to get a true idea of size, instead of just eyeing with a measuring tape. I've attached pics just for size & fit on my Heritage, it's not strapped down- no trips planned just yet. I am able to open my saddlebags without interferance and that was important to me. Aside from that, it seems to be a pretty great bag. Very well made and has enough space for everything I might need. Not too many pockets which is perfect for me. I saw the NR-220 at a rally in '23. It was a nice size but it's now discontinued. There is a NR-225 in the works but it won't be any bigger than the HD duffel I had been using. After comparing all major brands, types & sizes I chose this one. Can't wait to load it up & hit the road. Oh, the last pic is a comparison to my husband's Viking bag on the left. His is supposed to be 4 liters bigger than mine. Seems like my NR will end up larger if I let out the expansion zipper. Another bonus is that my bag is 3 lbs lighter. The only thing I like better about his bag is the side handles so it can be carried to our destination like a regular suitcase. The NR only has a handle on the back at the top, kind of awkward. No shoulder strap either. Very happy with purchase though. Seller had it very well boxed & it arrived a week earlier than arrival date.
