Abstract:
A saddle-ride vehicle includes a radiator body having a first radiator and a second radiator each including a core composed of radiating fins and tubes, alternately laminated. The radiator body is disposed forward of an engine while sandwiching a down tube between the first and second radiators in a vehicle left-right direction with the down tube extending rearwardly and downwardly of a head pipe. The radiator bodies and an exhaust pipe connected to the engine are disposed in an overlapping manner when the vehicle is viewed in a plan view. The lower tank of the first radiator include an inlet for the coolant from a lower communicating radiator hose that allows coolant to flow from the lower tank of the second radiator and an outlet for the coolant to a lower end radiator hose that is connected from the lower tank of the first radiator to the engine.
Abstract:
An intake system for a vehicle includes a connecting tube disposed to bypass one side of a rear shock absorber. The capacity of the intake chamber is increased to achieve an improvement in intake performance and to reduce the influence of a liquid intake-spitting component on intake air. The connecting tube is formed to include a tubular main tube portion and a funnel portion installed integrally and consecutively with the main tube portion. The funnel portion has a funnel-shape that broadens as it nears the air cleaner with an opening of the main tube portion on the upstream end. An intake chamber serving as part of a purified-air chamber formed between the funnel portion and the cleaner case is formed at least below the main tube portion. A drain member is provided with the lower portion of the funnel portion to communicate with the lowest portion of the intake chamber.
Abstract:
A forged head pipe for a motorcycle frame is integrally formed and includes a main frame attachment portion, a pipe portion, and a lower extension extending downwardly from the pipe portion. A down frame attachment portion is provided on the lower extension, and is spaced away from the main frame attachment portion and the pipe portion. A down frame is welded to the down frame attachment portion by contacting the same without inserting the same. The down frame attachment portion is configured from a connecting portion, extending in parallel to the pipe portion, and an extension extending rearwardly from a lower end portion of the connecting portion. By eliminating an insertion socket, manufacturing cost is reduced, and welding quality is improved by spacing the down frame downwardly below the main frame attachment portion and the pipe portion, to which a high load is applied.
Abstract:
A radiator structure includes a radiator body having a core composed of radiating fins and cooling water passing tubes alternately laminated and a bracket disposed at one end of the core. The bracket includes an extension portion disposed at a vehicle widthwise inner end of the core and extending along a vehicle front-rear direction. The extension portion has a fixing portion on a leading end thereof, the fixing portion being fixed to a mounting portion of a body frame. An indentation is provided in a portion of an opposed sidewall where a front end of the core and the opposed sidewall of the bracket overlap each other when the vehicle is viewed from the side and which overlaps the fixing portion at least in the vehicle front-rear direction. The indentation is formed by bending the opposed sidewall in a direction away from the front end.
