Here we have not the heaviest, but the world’s largest proper motorcycle (i.e. one not made out of a Russian tank). The 2 cylinder V-type Gunbus 410 is 11.5 ft long, with a volume of 410 cubic centimeters. That’s huge. Just look at the picture to get a sense of the scale. And unlike the previous ride, the designers of this chopper actually did give some consideration to performance.
