Two-wheeled vehicle
A two-wheeled vehicle includes a frame assembly having a front end and a rear end extending along a longitudinally-extending centerline, a front ground-engaging member operably coupled to the front end of the frame assembly at a front rotational axis, and a rear ground-engaging member operably coupled to the rear end of the frame assembly at a rear rotational axis. A wheel base is defined between the front and rear rotational axes and a vertically-extending centerline of the vehicle extends vertically at the midpoint of the wheel base and is perpendicular to the longitudinally-extending centerline. The vehicle also includes a fuel tank, an airbox assembly, and a battery all positioned relative to the vertically-extending centerline of the vehicle.
1. A two-wheeled vehicle, comprising:
a frame assembly having a front end and a rear end extending along a longitudinally-extending centerline;
a front ground-engaging member operably coupled to the front end of the frame assembly at a front rotational axis;
a rear ground-engaging member operably coupled to the rear end of the frame assembly at a rear rotational axis;
an engine supported by the frame assembly and operably coupled to at least one of the front ground-engaging member and the rear ground-engaging member, the engine including a front cylinder having a front cylinder head, a rear cylinder having a rear cylinder head, and a crankshaft operably coupled to the front and rear cylinders;
a seat supported on the frame assembly and configured to support at least an operator of the vehicle;
a fuel tank supported by the frame assembly and positioned under the seat, and a forward end of the fuel tank is approximately vertically aligned with the crankshaft,
wherein the fuel tank includes a rearward end longitudinally spaced apart from the forward end, and a vertical height of the rearward end is generally equal to a vertical height of the forward end.
2. The two-wheeled vehicle of claim 1 , wherein the forward end of the fuel tank is positioned rearward of the front cylinder.
3. The two-wheeled vehicle of claim 1 , wherein a lower surface of the fuel tank is supported on the frame at a position lower than the front and rear cylinder heads.
4. The two-wheeled vehicle of claim 1 , further comprising an airbox assembly supported by the frame and operably coupled to the engine, and the fuel tank extends from a rear end of the airbox assembly to a rear portion of the straddle seat.
5. The two-wheeled vehicle of claim 4 , wherein the airbox assembly is positioned above the front cylinder and the fuel tank is positioned rearward of the front cylinder.
6. The two-wheeled vehicle of claim 4 , further comprising a steering assembly operably coupled to the front ground-engaging member, and the airbox assembly is positioned longitudinally intermediate the steering assembly and the fuel tank.
7. The two-wheeled vehicle of claim 1 , wherein the fuel tank includes a fill cap positioned at a forward end of the fuel tank.
8. The two-wheeled vehicle of claim 7 , wherein the fuel tank includes a fuel pump positioned rearward and below the fill cap.
9. The two-wheeled vehicle of claim 1 , further comprising a battery supported by the frame at a position lower than the fuel tank and forward of the fuel tank.
10. The two-wheeled vehicle of claim 1 , further comprising a brake assembly operably coupled to at least one of the front ground-engaging member and the rear ground-engaging member, the brake assembly includes an anti-lock brake module, and the anti-lock brake module is positioned below the fuel tank.
11. The two-wheeled vehicle of claim 10 , wherein the anti-lock brake module is positioned longitudinally intermediate a forward portion and a rearward portion of the fuel tank.
12. The two-wheeled vehicle of claim 1 , wherein the fuel tank includes a rearward end longitudinally spaced apart from the forward end, and a vertical height of the rearward end is generally equal to a vertical height of the forward end.
13. The two-wheeled vehicle of claim 12 , wherein the fuel tank includes a center portion positioned longitudinally intermediate the forward and rearward ends, and a vertical height of the center portion is less than the vertical heights of the forward and rearward ends.
