I have been running the Bestem 929 top box both as a top box and side cases for a while now and have been very happy with them.
One common issue with just about any top-box is how slipper the inside is which contributes to having the top box content flying in
every possible direction as one gets on the road.
I had tried to alleviate the issue with some anti-slipping material which worked OK, until I found the perfect solution in the 929 liner
that Bestem is offering for just $19.95
It's a great add-on for stabilizing the content inside the top box, protecting the paint of one's helmet and for easy clean-up.
The seems to be injection molded and fits the 929 like a glove. I am very impressed with the craftsmanship and the quality of the liner.
Put together a quick farkle review which you can check out here: Farkle - Bestem 929 Liner Insert

I also use their bag liners for the side cases which makes packing for long trips a snap: Farkle - Bestem 929 Bag Liners
