A three-wheeled tilting frame with two front steerable, non-tilting wheels for scooters and motorcycles, having longitudinal center-line of symmetry, and which frame comprising:

• a front cross axle with two steerable, non-tilting wheels;
• a longitudinal, horizontal base beam attached to said axle on said center-line of symmetry, and said base beam having upper surface, on which said surface said base beam has mounted at least two horizontal, longitudinally in-line hinges, on said longitudinal center-line of symmetry of said frame;
• a longitudinal keel beam attached to said hinges on top of said base beam, and said keel beam is tilt-able sideways;
• a front aero shield, a seat, and a rear wheel attached to said keel beam, and tilt-able together with said keel beam;
• a steering mechanism having a handle bar and a vertical steering rod with a universal joint with a pivot pin, said universal joint is attached to said base beam and to said keel beam by slide fit bushings, and said universal joint having its pivot pin's center on said hinges horizontal center-line,
• and having said vertical steering rod connected to said handle bar and to said front wheels via shafts, push-pull rods and levers, thus providing steering during tilting and during straight ride.
