All maintenance has been done and works great ! One of the best reliable bikes , serious inquiry only cause i just moved to an apartment after i used to live in a house and i had the bike in the garage, now i don't have a parking for it.It's a 2002 with 6 speed and i just got 19k on it, new seat, paint and all the fuids changed, ready to go for many more years ... it's almost maintenance free bike,
