They are the OEM triumph bags. Holding up well so far, as i pretty much have at least the left side bag on all the time too. I'm a little concerned about the quality. No issues yet, but I'm worried the straps and the "twisty buckles" will fail over time. They are the Triumph mounts, that come with the bags. Look like chrome hangers on steroids. I'd suggest getting them powder coated before install. Something i will get done during the off season.
Quite right re the twisty buckles,my son walked past my bike and his shorts snagged the right side one, he didnt try to pull away hard or anything but the buckle pulled off, they're only held in by 2 triangle shaped spikes that are flatened in towards eachother,no strength at all. I plan on geting them modified by a leather worker to have belt type buckles.
