would appreciate some advice. Perhaps i am as dumb as dirt or some such but i have a new HD overnight bag. Packed it nice and full for a 450 mile trip. All within the weight limits though. Slipped the sleeve over the sissy bar and attached the two clips firmly around the sissy bar. the bag sits on the pinion seat. Cool and groovy. Except that the bag slips from side to side. It won't fall off but it does move the backrest very annoying. Any advice? Doing something wrong?

 

This is how I rode. Return trip in 10 days time and would love to resolve the issue before than. Ta

 

Perhaps a bungee net over the bag and connect to the rear turn signal stem to secure it from going side to side. Is it a HD bag?

 

 

I have one of those bags. Kind of hard to describe, but I route the straps under the rack and wrap the straps around the flat plate, vertical part of the rack on the opposite side and cinch them down snug. In other words, I attach the strap from the left side of the bag to the right side of the rack and vice versa. This way the strap pulls the sides of the bag in toward the center. You can still push the bag side to side some, but it's secure enough that it stays where it belongs when I ride. You can figure out how to route the straps and exactly where to attach them how you think is best, but I think the key is going to the opposite side.

The stiffener insert at the bottom is kind of flimsy, which contributes to the problem. I've read of people taking a plastic cutting board or something similar and replacing the original piece. I'm probably going to do that myself before the next road trip.

Probably not telling you anything you didn't already know, but put the heaviest things in the bottom.

 

Rok straps work great. Put one over the top.

 

I had a RGC with a Corbin Rumble seat--looked like a solo seat till I flipped up the passenger backrest to expose a flat spot for the passenger to sit and the passenger backrest was like a sissy bar as far as hanging a piece of luggage on it. The loaded piece of luggage could slip on the sissy bar forward of the passenger backrest and take up the passenger seating area and I could lean back against it while riding. Or, if I had a passenger I could hang the luggage on the passenger backrest with the luggage hanging off the back. But usually I had the luggage sitting on the passenger flat seating area to lean back against and it would move/slide sideways like yours is doing. My luggage piece had lots of tie down loops/hangers/etc. so I just secured a strap, one on each side, to a loop on the luggage about halfway up the side of the luggage. Routed the strap on each side down around the shock mounting bolt and snugged up both. Very solid. No more side slipping at all.

 

Yep. Buy some Rok Straps. Problem solved.
