That is an original 1991 Pine Mountain in North American colour scheme.
If it is simply a campus cruiser, then stick some Marin Rockstar forks on it and paint them to match that wicked paint job. The rigid forks are light and responsive, plus much cheaper.
Sympathy is beauty for this old horse!
Use period parts and love it to death. The bars will most likely be fine unless they have a fracture or split in the Titanium. I have crashed Ti bars and carried on using them for years with similar damage. If in doubt, chuck it out (or sell 'em on here for a garage queen).
