An engine clutch device includes first and second alternately stacked frictional power transmitting members and a clutch pressure member for axially bringing the frictional power transmitting members into pressure contact. The clutch device includes an oil supply portion adjacent to a distal end of power transmission shaft. The clutch device has an oil supply structure including a clutch lifter member with a flange portion axially facing the distal end of power transmission shaft, to axially shift the clutch pressure member to release the pressure contact of the frictional power transmitting members. The flange portion has a bowl-shaped portion extending axially to surround the one end portion of the power transmission shaft. The bowl-shaped portion including the flange portion functions to guide oil axially inward along the power transmission shaft and serves to provide an improved oil supply effect to the frictional power transmitting members.

A rear-wheel suspension system for a two-wheeled vehicle includes a pair of right- and left-side center frames; a swing arm; and a shock absorber, wherein the shock absorber includes a tubular buffer and a spring, wherein the intake system part is a curved tubular member, wherein a position of the spring is shifted downwardly so that the intake system part are moved toward an interior of the vehicle body by a dimension corresponding to the spring, wherein a lower end of the intake system part is above the upper end of the spring, wherein a part of the intake system part is closer than an outer end of the spring to the center of the tubular buffer, and wherein the shock absorber and the intake system part are disposed between a pair of right- and left-side center frames.

Rear-wheel suspension system for two-wheeled vehicle

A rear-wheel suspension system for a two-wheeled vehicle capable of further reducing a vehicle width. An upper end of a coil spring of a shock absorber includes a tubular damper case, a rod connected to a piston disposed within the shock absorber and protrusively provided to be capable of making strokes with respect to the tubular damper case and an external hydraulic sub-tank positioned to be lower than an upper end of the shock absorber. Vehicle body component parts include a connecting tube and the sub-tank disposed to be close to the shock absorber above the coil spring.

An exhaust device of an internal combustion engine for reducing exhaust sound and for suppressing the occurrence of a torque valley. A sound-deadening and pressure-dissipating device connected to the downstream end of an exhaust pipe includes a spherical member having an opening portion opening toward a downstream edge of the exhaust pipe. Exhaust gas from the exhaust pipe is reflected by an inner spherical surface of the spherical member to reduce exhaust pressure in the spherical member and then is discharged from the opening portion.

A structure for mounting a rear fork in a vehicle, including a body frame having left and right pivot supporting holes; left and right arm portions of a rear fork having supporting holes which are coaxial with the right and the left pivot supporting holes of the body frame a pivot shaft penetrating the pivot supporting holes of said body frame and the supporting holes of the left and right arm portions of the rear fork, said rear fork being rotatively supported on the pivot shaft and being rotatable with respect to said body frame. A tapered cutout is provided on the end surface portion of the collar to be pressed into the pivot supporting hole of the engine, so as to allow the pivot shaft to deflect.
