An engine suspension structure for a two-wheeled vehicle, comprising a vehicle body frame (11); an engine (12) suspended from the vehicle body frame (11); down frames (18L, 18R) forming a portion of the vehicle body frame (11) and extending vertically at the front of the vehicle body frame (11); and mounting plates (44) for connecting the down frames (18L, 18R); and hangers (55) arranged on the engine (12) for thus mounting the engine (12) to the vehicle body frame (11), wherein the down frames (18L, 18R) comprise left and right down frames split in the vehicle width direction and extending vertically downwards; mounting plates (44) formed into a U-shaped cross-section that is exposed towards the hanger (55) and having left and right walls; mounting plates (44) fixed in such a way that they are sandwiched between the down frames. The left and right undercarriage frames (18L, 18R), the left and right walls of the mounting plate (44) are welded by cross member (88). The left and right undercarriage frames (18L, 18R) are provided by ring members (121L, 121R) with holes (131, 131) extending horizontally through them. The mounting plate mounting parts (76) are provided, extending through holes (131, 131) of the ring member (121L, 121R) and the cross member (88) to be bonded together with the left and right undercarriage frames (18L, 18R), and the cross member (88) is made to extend outward in the vehicle width direction from the left and right face of the mounting plate (44) positioned between the left and right undercarriage frames (18L, 18R) and to come into contact with the front end of the inner part of the ring member (121L, 121R). 2. The engine hanger structure of claim 1, wherein the mounting plate (44) and the hanger (55) are attached together by the engine hanger mounting member (75), with the hanger (55) being held in place by the mounting plate (44), the engine hanger mounting member (75) being designed to attach the hanger (55) from the outside of the mounting plate (44). 3. The engine suspension structure of claim 1 or 2, wherein the transverse member (88) has a recess (133) formed in its front portion to avoid interference with the exhaust pipe (65) extending from the engine (12). 4. The engine suspension structure of any one of claims 1 to 3, wherein the mounting plate (44) has a front wall (86) positioned towards the front of the vehicle, and at least one opening (111) is created in the front wall (86). 5. An engine suspension structure for a two-wheeled vehicle, comprising a vehicle body frame (11); an engine (12) suspended from the vehicle body frame (11); down frames (18L, 18R) forming a portion of the vehicle body frame (11) and extending vertically at the front of the vehicle body frame (11); and mounting plates (44) for joining the down frames (18L, 18R); and hangers (55) arranged on the engine (12) for thus mounting the engine (12) to the vehicle body frame (11), wherein the down frames (18L, 18R) comprise left and right down frames split in the vehicle width direction and extending vertically downwards; mounting plates (44) formed into a U-shaped cross-section open towards the hanger (55) and having left and right walls; mounting plates (44) fixed in such a way as to be sandwiched between the down frames. On the left and right side undersides (18L, 18R), the left and right side walls of the mounting plate (44) are welded by the cross member (88), and the cross member (88) has a recess (133) created in its front part to avoid interference with the exhaust pipe (65) extending from the engine (12). 6. An engine suspension structure for a two-wheeled vehicle, comprising a vehicle body frame (11); an engine (12) suspended from the vehicle body frame (11); down frames (18L, 18R) forming a portion of the vehicle body frame (11) and extending vertically at the front of the vehicle body frame (11); and mounting plates (44) for joining the down frames (18L, 18R); and hangers (55) arranged on the engine (12) for thus mounting the engine (12) to the vehicle body frame (11), wherein the down frames (18L, 18R) comprise left and right down frames split in the vehicle width direction and extending vertically downwards; mounting plates (44) formed into a U-shaped cross-section open towards the hanger (55) and having left and right walls; mounting plates (44) fixed in such a way as to be sandwiched between the down frames. The left and right side lower panels (18L, 18R), the left and right side walls of the mounting plate (44) are welded by the cross members (88) and the mounting plate (44), there is a front wall (86) positioned towards the front of the vehicle, and at least one opening (111) is created in the front wall (86). ---------------------------------------------------------------------------------
