Straddle-type vehicle
A straddle-type vehicle has reduced wiring and a mass of the vehicle as measured in top-to-bottom and front-to-rear directions with respect to the vehicle is concentrated while minimizing the effects of heat from the engine on an engine control unit and ignition coil. An air cleaner is located rearward of a head pipe. A fuel tank is located rearward of the air cleaner. A rear portion of the air cleaner is located above the engine. A front portion of the fuel tank is located above the engine. The engine control unit and the ignition coil are located above the engine and located between the air cleaner and the fuel tank. The ignition coil overlaps the engine control unit as viewed in a side view of the vehicle.
1. A straddle-type vehicle comprising:
a head pipe;
a pair of main frames extending rearward from the head pipe;
an engine supported by the pair of main frames;
an air cleaner located rearward of the head pipe;
a fuel tank located rearward of the air cleaner;
an engine control unit configured and programmed to control an operation of the engine; and
an ignition coil configured to supply a voltage to a spark plug included in the engine; wherein
a rear portion of the air cleaner is located above the engine;
a front portion of the fuel tank is located above the engine;
the engine control unit and the ignition coil are located above the engine and located between the air cleaner and the fuel tank; and
the ignition coil overlaps the engine control unit as viewed in a side view of the vehicle.
2. The straddle-type vehicle according to claim 1 , wherein the engine control unit and the ignition coil overlap the pair of main frames as viewed in a side view of the vehicle.
3. The straddle-type vehicle according to claim 1 , wherein
the air cleaner includes a base member attached to the pair of main frames; and
the base member includes:
attachment portions each including an insertion hole through which a bolt to attach the base member to the pair of main frames is to be inserted;
a first support located closer to the engine than the attachment portions are, the engine control unit being attached to the first support; and
a second support located closer to the engine than the attachment portions are, the ignition coil being attached to the second support.
4. The straddle-type vehicle according to claim 1 , further comprising:
a connecting cord configured to connect the ignition coil with the spark plug; and
wiring extending from the engine control unit; wherein
the wiring is arranged to be non-parallel to the connecting cord.
5. The straddle-type vehicle according to claim 4 , wherein
the wiring extends downward from the engine control unit;
the ignition coil includes a cord support located rearward of the engine control unit as viewed in a plan view of the vehicle; and
the connecting cord extends from the cord support toward one side of the vehicle disposed in a vehicle width direction that is adjacent to the engine control unit, and passes behind the wiring.
6. The straddle-type vehicle according to claim 4 , wherein the connecting cord includes:
an extending portion connected with the ignition coil and extending from the ignition coil toward one side of the vehicle disposed in a vehicle width direction that is adjacent to the engine control unit;
a curved portion connected with the extending portion and curves as viewed in a plan view of the vehicle; and
a plug cap connected with the curved portion and attached to the spark plug.
7. The straddle-type vehicle according to claim 1 , wherein a lowermost point of the fuel tank is located lower than a lowermost point of the air cleaner.
8. The straddle-type vehicle according to claim 1 , wherein
the engine includes a cylinder; and
a foremost point of the fuel tank is located forward of a rearmost point of the cylinder.
9. The straddle-type vehicle according to claim 1 , wherein the engine control unit and the ignition coil are located higher than a lowermost point of the fuel tank.
