Hi, /wsr/

I'm looking for an old movie. My guess is an 80's movie. It is one of those "kids on an adventure" movie.

The thing I remember the most is that one of the kids had one of those motorcycles with a passenger pit and a think it was his little brother the one that rides it.

Sorry if I can't be of more help, but I was very little when I saw it. I remember it was fun I wanna watch it again with my little sister.

Thanks, everyone.
