Duckster is correct on condition versus age. A bike stored on jackstands/elevated off the ground in an enclosed garage for five or ten years will have much better tires than a bike that is parked out in the sun for the same period.
Also noteworthy, most of the "five year" tire research is regarding radial tires, something we don't have to worry about with our bikes. For whatever reason (I postulate that it has something to do with the facebook analogy of lowest common denominator and the widespread displays of such on the internet in general), that somehow got ported over to non-radial motorcycle tires.
"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.
