A cage for a bearing, including: a first annular segment; a second annular segment located radially inwardly of the first annular segment; a vane connected to the first annular segment and to the second annular segment and including a first axial end facing at least partly in a first axial direction parallel to an axis of rotation of the cage and a second axial end facing at least partly in a second axial direction, opposite the first axial direction, the second axial end off-set from the first axial end in a circumferential direction around the axis of rotation; and a curved surface connected to the first annular segment and the second annular segment and arranged to retain a ball of the bearing. The first annular segment, the second annular segment, the vane, and the curved segment define a channel passing through the cage.

The invention provides a motorcycle having a frame, an engine coupled to the frame, and a crankshaft assembly. The crankshaft assembly includes a first flywheel half having an aperture, a crank pin including a first end portion, a second end portion opposite the first end portion, and a bearing surface between the first and second end portions. The first end portion is press-fit into the aperture of the first flywheel half. The first end portion, the second end portion, and the bearing surface are coated with a friction enhancer. A bearing is positioned at least partially onto the bearing surface, and a connecting rod has an aperture that at least partially receives the bearing.
