...for the back on my '97? I just got the bike and it has a brand new 021 Bridgestone on the front BUT it has what I'm sure is the original Bridgestone 054 on the rear. It's in great shape (bike has 4000 miles on it) but am thinking if the front's new, so should the back. Bike is used for city riding/commuting and weekend rides-not a lot of twisties in NM. So should I just get a 021 for the rear or does Bridgestone make something that would work better for me? Thanks for all your help.
