Method of reinforcing a motorcycle frame during conversion to a motorized tricycle

Abstract

A method of reinforcing an L-shaped motorcycle frame during conversion to a motorized tricycle. The L-shaped motorcycle frame is an inverted L-shape with a horizontal portion and a vertical portion. A tricycle frame is provided having spaced apart side plates with a forwardly and downwardly extending portion which terminates in a mounting attachment. The side plates are fastened to opposed sides of the horizontal portion of the L-shaped motorcycle frame. The mounting attachment is secured to the vertical portion of the L-shaped motorcycle frame. This forms a triangular truss with the forwardly and downwardly extending portion of the side plates of the tricycle frame angled between the horizontal portion and the vertical portion to provide rigid support to the L-shaped motorcycle frame.

1 . A method of reinforcing an L-shaped motorcycle frame during conversion to a motorized tricycle, the L-shaped motorcycle frame being an inverted L-shape with a horizontal portion and a vertical portion, comprising:
 providing a tricycle frame having spaced apart side plates with a forwardly and downwardly extending portion which terminates in a mounting attachment;   fastening the side plates to opposed sides of the horizontal portion of the L-shaped motorcycle frame;   attaching the mounting attachment to the vertical portion of the L-shaped motorcycle frame to form a triangular truss with the forwardly and downwardly extending portion of the side plates of the tricycle frame angled between the horizontal portion and the vertical portion to provide rigid support to the L-shaped motorcycle frame.   
     
     
         2 . The method of  claim 1 , wherein the triangular truss forms a right angle triangle, with the forward struts of the tricycle frame providing a hypotenuse. 
     
     
         3 . The method of  claim 1 , wherein the tricycle frame forms a motorcycle frame support that supports the L-shaped motorcycle frame from below. 
     
     
         4 . The method of  claim 1 , wherein an auxiliary pivot support having an interior surface defining a bushing is secured to the mounting attachment to provided additional support to a pivot pin for a tricycle swing arm. 
     
     
         5 . The method of  claim 1 , wherein an auxiliary shock absorber is secured between an upper shock mount on the tricycle frame and a lower shock mount on a tricycle swing arm, the auxiliary shock absorber being centrally positioned between the side plates of the tricycle frame and centrally positioned between two rearwardly extending portions of the tricycle swing arm.
