Describe mono-shock regular swing arm suspension system with neat sketch.

1 Answer

Answer :

Mono-shock Regular swing arm : Original technology of mono-shock comes from the racing world where motor cycles compete in most extreme conditions. More advanced version of this technology is employed in these bikes. Many models now a days incorporate this type of shock to give statement of style and comfort.

The fundamental idea behind eliminating one of the suspension strut is to reduce overall weight. Furthermore, by placing the rear suspension strut closer to COG of the vehicle, turning characteristics, stability during braking and overall riding performance can dramatically improve. It is easier to adjust the ride height, since there is only one shock to adjust, and there is no worry about matching two shocks.
