Motorcycles, my Wife Doesn't Understand It

My wife just does not get it about my motorcycle fetish and how it just won't die. That's okay, at least she does not try to stand in the way of me having one. She says she thinks they're pretty and she knows how fun they can be (She use to ride dirt bikes) but the street bikes leave her a bit unnerving. Although she won't help me with them she doesn't piss and moan about it either. She's just concerned I recon. And even though she has said she won't help me any she has with trouble shooting and asking if I've checked this or that. But she still says she don't get it. We have and she has women friends who ride even.
