Hi. I have finally saved enough allowance to be able to retire my '85 K100 bike. I am looking at a comparison of these two tires on ebay: Continental Go set for $234.16, and Michelin Pilot Activ set for $294.96. the Contis were recommended by my local tire shop, and the Michelins were recommended by my local BMW shop. My question is: is it worth $60 more to get the Michelins?
