Fictional would have to be either:
Hunter, the biker hero in the film Battletruck!
Self-sufficient man of few words biker.
Run's his bike off methene fuel and even had a solar paneled-up BOL!
No machine gun mounted fancy-machines for him. But enough arms to take on maurading bully's like the boys with the Battletruck.
Or
Max Rockatanski's another cool role model
Real word one's are several, Hugh Glass, Albert Johnson, Bear Grylls etc.
