Abstract

A method for manufacturing a motor cycle that adopts a dry sump system as a lubricating system and includes a tank in frame utilizing a portion of a vehicle body frame, the method includes steps of (a) forming an oil tank assembly 100 from a head pipe 10, a down tube 12 and a gusset 14, (b) carrying out a leakage test of a space defined by the head pipe 10, the down tube 12 and the gusset 14, and (c) connecting a main frame to the head pipe of the oil tank assembly after the step (b), the main frame extending rearward from the head pipe. <IMAGE>

Description

technical field [0001] The invention relates to a method for manufacturing an automatic two-wheel vehicle. Specifically, it relates to a method for manufacturing a motorcycle using a dry sump lubrication system including a tank in frame in which a part of the frame is utilized as an oil tank . The present invention also relates to a frame inner box of an automatic two-wheel vehicle and an automatic two-wheel vehicle with the frame inner box. Background technique [0002] As a lubrication method for motorcycles, in addition to the wet oil pan type in which the pump pumps up the oil stored in the oil pan at the bottom of the engine and sends it to the engine lubricating part, there is also a method that separates the oil tank from the engine and utilizes the A dry sump type in which the oil in the oil tank described above lubricates the engine. Adopting the dry oil sump type has the following advantages: the capacity of the oil pan can be reduced, the expansion of the lower...
