F1 Haro? The picture of yours isn't one. F1s all had an aggro geometry. Someone had the bright idea of building a more conventional "small" bike for asphalt parking lot races. It went nowhere.
I think, you're thinking of the Dart F1, which was Haro's tiny track bike. They've since reused the F1 name on freestyle bikes.
