I have these currently and can't wait to change them. I ride my bike every day and these tyres don't fill me with confidence. I have had a fair few wriggles in places where I wouldn't expect to and the tyres are on my mind more than they should be.
My previous GS had Roadtec 01's on it and these felt so much better. More sporty I guess and certainly preferable for me as all of my riding is either pottering around town or more pointedly, brisk progress through the Peak District and further afield. Interesting too that I could jump off my old 1250 with the half worn Roadtec's and jump on to the new bike with the A41's and feel immediately uneasy after they were scrubbed in.
My overall view is that tyres are a personal thing and how you ride affects the suitability of some and not others - the Metzelers suited me, the Bridgestones do not. Am doing a Scotland tour this month and once I am back, the A41's will have done over 2500 miles so I think I will change them. I am keen to try Conti Trail Attacks next although can really recommend the Roadtec tyres very highly - excellent performance.
