I have two girls, ages 4 & 7. The four year old doesn't care about the bike, she just likes to look at it and sit on it. But my 7 year old wants me to take her for a ride on it. I keep telling her that I have to get more comfortable on the bike before I can have any passengers on it (only had the bike for a couple of weeks now). Plus I have to get her a helmet too. So my wife (who just doesn't like motorcycles because "their so dangerous") says she's too young to get on a motorcycle. I was just curious about those of you who have kids; do you let them ride on your motorcycle and if so, how old were they when you started?
