From outside the hobby, it is easy to see that most modifications we make to our vehicles decrease the usability, not increase it. Most mods made to diesel pickups (bed stacks, lifts, chips) actually make them worse. Most mods made to ricers (lowering, fart cans, body kits, spoilers) actually make them worse. Unfortunately it is probably the same for motorcycles. We just can't see it because we are inside the lifestyle.
