This is hands down the best tire i have ever run i run the road two on the rear and a standard pilot power on the front of my buell and could not be happier. I do alot of commuting and alot of mountain riding so my tires see a lot of abuse and these are great! I use one set a year and put about 8k on them. They are great in the wet and still give great feedback and grip when you want to get a little crazy in the mountains. Havent put a set on my 675 yet but im sure they will be michelins.
