Abstract

A fuel tank for a two-wheeled vehicle mounted between two spaced side frames within a chamber defined under the seat, in back of an engine and in front of a rear fender. The fuel tank corresponds in shape substantially to the shape of the chamber. The fuel tank is laterally encompassed between the side frames and is suspended from above by brackets fixed to the side frames.

Claims

1. In a motorized two-wheeled vehicle having a vehicle body composed of a pipe frame, a front wheel, a rear wheel, driver'"'"''"'"'s seat in the frame, an internal combustion engine mounted at the front lower portion of the frame, and a fender for the rear wheel at the rear portion of the frame, an improvement wherein a fuel tank is mounted on said body, said pipe frame, seat, engine and fender defining a substantially enclosed chamber in which said fuel tank is fixedly secured, said fuel tank having a shape substantially conforming to the shape of said chamber;

said pipe frame comprising a pair of left and right side frames having a space therebetween, said chamber being defined within said space, support means mounting said fuel tank from said side frames, said support means comprising a pair of spaced brackets secured to said side frames, and means suspending said fuel tank from said brackets, said fuel tank having a concavity therein at the front thereof, and resilient means supported from said side frames and engaged in said concavity.

2. An apparatus as claimed in claim 1 wherein said means suspending the fuel tank from the brackets comprises further brackets secured to the fuel tank and attaching means connecting the respective brackets and further brackets.

3. An apparatus as claimed in claim 1 wherein said resilient means comprises a transverse member extending between said side frames and an elastic member with a projection engaged in said concavity.

4. An apparatus as claimed in claim 1, comprising a housing secured to said body and disposed in front of said seat, said fuel tank having an inlet accessible through said housing.

5. An apparatus as claimed in claim 4, comprising an air cleaner for said engine within said housing.

6. An apparatus as claimed in claim 6, wherein said side frames laterally encompass said fuel tank.
