Actually it's aYamaha. I made the mistake of firing it up in the garage while she was there. My fiance was holding her at the time and she was curious about what daddy was doing. But when the bike fired up, the low rumble echoed in the garage and scared her. So I had to explain to her what the noise was. I know it will be awhile before she's ready to be around glow engines. When she gets a little older I'll take her to our field and let her watch the planes fly there and hopefully she'll like that.
