Motorcycle having body height adjustor

A motorcycle having a body being adjustable in height, comprising:

• a front fork supported axially and rotatably on a body frame, said front fork supporting a front wheel in a shock absorbing manner by a pair of front suspensions;
• a rear cushion unit supported on said body frame, said rear cushion unit supporting a rear wheel in a shock absorbing manner;
• an engine mounted on said body frame to drive and rotate said rear wheel;
• and
• a body height adjustor capable of adjusting the body height of the motorcycle by changing the lengths of said front suspensions and said rear cushion unit, said body height adjustor including:
• a first hydraulic jack provided on said rear cushion unit to enable body height adjustment;
• second hydraulic jacks provided on said front suspensions to enable body height adjustment;
• a body height adjusting unit capable of transmitting a hydraulic pressure of a pressure fluid in said rear cushion unit to said first and second hydraulic jacks through hydraulic hoses;
• and
• a hose connector provided on said hydraulic hoses connecting said body height adjusting unit and said second hydraulic jacks of said front suspensions, said hose connector being disposed at the rear of said front suspensions and in front of said body height adjusting unit.
