I tried to find a Triumph topcase for my Tiger, but since I use my eyes to ride, I was averse to having them torn out. I'm not affiliated with this auction, but I did buy one and just got it today. Took about 15 minutes to mount it to the Tiger. Super deal. Way more than half as nice as a Givi, 46 liters, (put my Quantum II & my Vemar in there together, no sweat) led light, liner and universal mounting kit for $80 delivered. Steal!! These guys were real easy to work with, shipped it the next day & I got it in three business days. I'm super pleased. Thought I'd post it here in Tigerland, but it would work on just about any rack.
