The suspension system of light weight vehicles,heavy vehicles and motorcycles vary a lot. What is the reason for choosing these different suspension systems?
Strut suspensions are common because they are simple and cheap to engineer and take up little volume. Multi-link independent suspenions offer more precise wheel control but are complicated, expensive and consume more volume. Semi-trailing arm rear suspensions are a simpler alternative but don't offer as precise control over wheel movement. Solid axles with leaf springs are the simplest mechanical device known to man. Solid axles with coil springs offer better ride and control at the cost of increased complexity.
The suspension is how much give the car has in different enviroments. It also is better for certain vehicles in different terrien. You would not not want a vehicle with light weight suspension to take 4 wheeling. It would not hold up and you would end up with more damage then car.
