Load mechanism for debugging running-in of motorcycle engine

The utility model relates to the field of load mechanisms, in particular to a load mechanism for debugging and running-in of a motorcycle engine, which comprises a base, a speed reducer, a control handle, a friction piece, a rotating shaft A, a rotating gear A, an input interface, an input shaft, a rotating gear B, a rotating gear C, a rotating support, a rotating gear D, a rotating gear E, an unlocking device, an output shaft, a torsion piece and a generator. The base is connected with the generator; the generator is connected with the output shaft; the base is connected with the speed reducer; the side of the speed reducer is rotationally connected with the control handle; the control handle is in control connection with the friction piece; the friction piece contacts with the side surface of the rotating shaft A; a through hole is formed in the speed reducer, and the rotating shaft A penetrates through the through hole; the rotating shaft A is connected with the rotating gear A; and the rotating gear A is
