If you have solid engine mounts, there's nowhere for the power to go but through the chain. With rubber mounts some of the engines power is absorbed as the motor twists in the chassis.

Think of walloping your thumb with a steel or copper hammer, and then a rubber one... sure, the rubber one will transfer enough energy to hurt, but not as much as the metal one, as the flex in the rubber will absorb some of the impact!

HRC engine mounts that are made from a stiffer rubber compound can be used on later bikes, or even better results can be had by turning up solid nylon mounts, but that's when the harshness starts to set in. The MC18, '21 and '28 all have a "torque link" between the motor and the swingarm too, to help reduce twist, but the MC16 doesn't need one because of the solid mounts.
