This is a Haro Function F4 (4130) trick bike. 20 " frame, 1-1/8 ORYGwith TekTro Brake system & 2K knee saver. Color is Gun metal, needs a cleaning. Been in storage over the past years. It`s a stout Frame & is built tuff & strong for hard riding. This ride was never used to its potential, so outside of needing tubes (maybe tires, not too sure about that) Its good to go! Brakes show no ware.
