I have a 1994 Yamaha Seca II that I have been riding for about two months and after about 4500 miles I need a new back tire, possibley a front too. About 80% of the 4000 were spent in the canyons and the previous 500 were done by the previous owner. This is my first bike so tire selection is a mystery. My bike is pretty low powered, about 55 Hp and maybe 40ft. lbs. of torque. What would you guys recommend if mileage isn't too much of a concern. I want to be confident with my grip, I never could with this set of Barracudas.
