i've had a KURY ultra tour for 5 yrs. w/ no sissybar. awesome bag. tons of room and 4 side pockets are expandable.

 

I have the back rest, pad and luggage rack with a two bag combo. Large overnight and a daytimer bag. All from HD.

 

I had a sissy bar and used a Saddlemen and a round bag from Bikers Friend. The Bikers Freind round bag will not collape and it comes with a backrest pad that attaches with velco. They are little pricey but the best investment in a bag I ever made.

 

Saddleman Sissy bar bags are the way to go with the divider and all the extra pockets. Has saved me numerous times on carrying all kinds of junk like my flak jacket and other gear when going to work or just simple road trips.

 

I have one for sale cheap... speedlimit@rocketmail.com
