Got a bridgestone potenza pole position rf(36psi).got it mounted at friends shop.ran home put it on and went for a short test ride.really couldn't tell the difference. On the way home I ran across a customer I did work for that runs a full on goldwing.when I showed him what I did his eyes lit up and he began to tel me how has wondered. So to his suprise I tell him go you got ten minutes. Yes I warned him tire might be greasy cause it was not broken in.he gets back and says I couldn't tell.next week I will be doin his.did a ride the next day with a big group of bikes me and the wife ran with the front of the pack and out ran every vtwin and never leaned bike over this far before.the front tire is now worn all the way to the edge!
