ABSTRACT:
To decrease adhesion of dirt to a radiator, miniaturize the radiator in front of an engine and improve engine cooling performance by efficiently applying cooling air to the engine. An oil cooler includes a first oil cooler and a second oil cooler. The first oil cooler is disposed in front of an engine. The second oil cooler is disposed in a front cover at a position higher than an upper edge of a front wheel. The first oil cooler is disposed immediately in front of a cooling fan. The first oil cooler is disposed so as to close an air intake guide of the cooling fan less than 50%. The first oil cooler and the second oil cooler are serially connected along an oil line. A heat radiation area of the second oil cooler is larger than that of the first oil cooler.
