Abstract

PURPOSE:To aim at reduction in physical fatigue on a rider and improvements in safety, by setting up an air cleaner in front of a front cylinder sideways, while constituting a setting structure so as to keep off any interference between driver's legs and the air cleaner. CONSTITUTION:An almost oval air cleaner extending lengthwise is set up in front of a front cylinder 3 from both sides, right and left, while a suction duct 20 connected to the downstream side of a suction discharge pipe 16 is extendedly installed in the rearward so as to cover an upper part of the front cylinder 3, and two suction interconnecting pipes 21 and 22 are connected to a lower surface at the upper part of a V-bank between two cylinders 3 and 4. With this constitution, driver's legs are in no case touched to the air cleaner 13 and, what is more, capacity in the air cleaner is able to make it yet larger, and improvements in safety and reduction in a noise both are well promotable.

is located. As shown in FIG. 2, the air cleaner 18, which has a substantially oval shape extending back and forth when viewed from the side, is mainly made of a hollow resin section, and is fixed to the vehicle body frame 10 by a bracket 14 or the like shown in the figure. As shown in FIG. is open. As shown in FIG. 2, the downstream end of the intake discharge pipe 16 opens at the front side surface of an intake duct 20 made of resin.

The downstream ends of cylinders 1 and 22 extend substantially downward, and are connected to a capretor 28 for both cylinders 8.4 (only the front cylinder 8 is shown) arranged in the bank. In addition, as shown in FIG. 4, the duct 201 is also made of a relatively flat member in the left and right direction, and by covering the front cylinder 8 from above, the engine 2 is protected against the fuel tank 11 located further above. It is also designed to completely block heat.
