Abstract: In a saddle-ride type vehicle in which a cylinder includes a cylinder head and a cylinder head cover that covers an upper portion of the cylinder head, a vehicle body frame includes a head cover adjoining portion that adjoins the cylinder head cover. At least a part of the cylinder head cover overlaps the head cover adjoining portion as viewed from a direction along a cylinder axis that is a center axis of the cylinder. The head cover adjoining portion extends rearward such that the cylinder head cover is exposed outside in a side view. The foregoing configuration seeks to affect the ease of mounting and dismounting a saddle-ride vehicle having a power unit with a cylinder arranged upward and the vehicle body frame for supporting the power unit by reducing the left-right width of a vehicle body frame while allowing a cylinder head cover to be attachable and detachable.
