Abstract: A seat frame for a motorcycle includes a plurality of aluminum parts manufactured with different manufacturing methods. A seat frame includes front members, middle members, and a rear member, the front members, the middle members, and the rear member being formed of aluminum. The rear member is formed by integral molding based on a gravity casting method. The rear member includes a pair of left and right rail portions, a front cross portion, a rear cross portion, and a plurality of attachment bosses for attaching other parts. The left and right rail portions each have an attachment portion to be connected to a rear end portion of corresponding one of the middle members provided on an end portion thereof on the front side in the vehicle longitudinal direction.

Abstract: A handle weight mounting structure of a saddle-ride-type vehicle includes a dynamic damper on the inside of a handle pipe while rigidly mounting a handle weight. A hollow handle pipe is provided with the handle weight arranged in the handle pipe by insertion from an outer end of the handle pipe. The handle weight includes a bolt insertion hole having a tapered portion on an inner portion thereof in the vehicle widthwise direction. A split groove with a nut member is formed into a tapered shape and is engaged with a split-groove side of the handle weight. A weight fixing bolt passes through the bolt insertion hole of the handle weight and fastens the handle weight and the nut member to each other. A mounting member for a dynamic damper is supported on the inside of the handle pipe in a floating state and is mounted on the nut member.
