I would be interested in comments and recommendations. I too have been thinking on a more aggressive set of tires for my R850R. I ride it mostly on loose gravel and dirt fireroads, but I get there on pavement. There have been some comments recently on Continentals 2s and 3s and what appears to be a very aggressive model ( I think it was called a TCK or TKC ) that did not get good reviews as to life expectancy.............the tires not yours! Good luck. Regards, Dan
