It is a science fiction book, that was published probably before 1995.

Two people on the run, in a distant future/society. I don't remember much but I do remember there was an older man, and a younger boy on this "escape". The older man has some sort of abilities to give the kid memories, or special thoughts if I remember correctly.
The older man gets caught by a "biker" like gang, and gets tied up and torn apart by the bikers.


Any ideas on the name?
