ABSTRACT:
An improved steering assembly for a tricycle comprises a front fork whose tubular stem is received in a head tube and has a flat area which is engaged by an internal projection extending from the wall of the head tube toward the head tube axis so as to limit the angular excursions of the fork about that axis and thereby prevent the tricycle from tipping over due to oversteering.
