I have a difference experience with Karoo 3s. In my experience best 50/50 tire. Iíve used them on my GSA and Africa Twin. Excellent wet weather grip on the tarmac and excellent off-road grip even in sand. I regularly ride sections of the COBDR and Karoo have always performed very well.
Iíve also used Shinkos, TKCs, and Mitas. While the Mitas lasted a long time. They had a 200 mile break-in and were slippery on road. The TKCs were good in the dirt but so-so on pavement. And they didnít last long.
Karoo said didnít last long on the 1200 GSA either, about 4K and they were done.
Just my .02
