Nice, are they synthetic?
Im replacing my faux leather bags with hard plastic cases, they got worn and damaged around the suspension spring, coming apart at the seams and one burned a bit on the exhaust when I removed it.
I'm thinking of repairing them and try selling them on.
On a side note, I've been led to believe the chain gets tighter as you put weight on the bike? it looks like your chain is already taut, might be worth loosening that to help reduce wear? (or at least checking it?) just a suggestion.
On another side note the scenery looks nice, nice and dry too? and warm?

I hazarded a guess it might be Arizona, then checked your location, looks like its local to you, nice.
