I had the Rally STR on my Scrambler 1200 XE and wasn't impressed. Even new they looked like they had 3-4000km on them. Didn't last, wasn't that impressive offroad and overall I didn't find them better in any way over the Shinkos. The TKC80 rear tire wears so fast and square, I've also eliminated those from my options, and you tend to feel the vibrations much more. They look good and do well offroad, but again overall, I still prefer the Shinkos.
