Just purchased a 2013 f800gs which came with the Metzeler Karoo 2 T tires mounted on it. Looking for a recent review on them. Haven't ridden them yet and was curious what to expect. Performance on/off road. Longevity and ect. So far some of the reviews online haven't been good, but most reviews seem to be out dated and don't distinguish between T and non T tire. On another note of a 50/50 tire, looks like the Heidenau K60 Scout gets great reviews.
