## Abstract

The present invention is a heat exchanger for a motorcycle which is adapted to be installed on the motorcycle in a substantially horizontal orientation. Also, the present invention is a heat exchanger for a motorcycle which is adapted to be installed on the motorcycle beneath the engine and/or beneath the crankcase and/or beneath the oil pan and/or beneath the gearbox. Preferably, the heat exchanger is made with finned tubular core elements. At the location under the motorcycle, the thinness of the heat exchanger is important, so preferably it is made with thin hollow plates. Preferably, the heat exchanger is installed in a suspended maimer beneath the motorcycle, so that cooling air may pass effectively over its top and bottom surfaces. Preferably, the heat exchanger is an oil intercooler.

## Claims

### Claim 1

A heat exchanger for the engine a vehicle, said exchanger being adapted to be installed on the vehicle in a substantially horizontal orientation beneath the vehicle.

### Claim 2 (depends on 1)

The heat exchanger of claim 1 which is an engine oil intercooler.

### Claim 3 (depends on 1)

The heat exchanger of claim 1 an engine cooling water radiator.

### Claim 4 (depends on 1)

The heat exchanger of claim 1, which exchanger is suspended beneath the vehicle, so that cooling air may pass over both the top and bottom surfaces.

### Claim 5 (depends on 1)

The heat exchanger of claim 1 wherein the vehicle is a motorcycle.
