It's hard to explain to non-moto inclined people what the attraction to motorcycles is. Not entirely sure, but I think moto-mania may be a genetic trait, because it's so hard to make a rational explanation for it. Doesn't really matter anyway - I stopped trying to explain it a long time ago. In my opinion you've either got the motorcycle gene, or you don't - not much you can do about it either way. If you do have the motorcycle gene, then you can probably identify with quote from Jack London below as well.
