Put EXPs on my BMW R1200GS replacing standard Tourance. Only done 1000 miles on them, and they feel like excellent road tyres. Good grip wet and dry. They feel very stable when braking hard and in bends. Doubt that they would fare well off-road, but I wouldn't be happy taking the GS off-road on anything rough without proper knobbly tyres like Conti TKC 80s.
More expensive than standard Tourance at �200 fitted. (Standard Tourance cost around �160 fitted to a GS.)
No idea if they were worth the extra money until they have shown how they wear. People on GS sites say they are wearing well.
Going on a tour of Ireland next week, so they will be in use on rough tarmac, probably in very wet conditions. I'll let you know if they misbehave.
