In the simplest terms, choosing the right Frame for a trike can make all the difference. Vehicles that have high torsional rigidity deliver a superior ride, superior handling and better response to driver input. Improving the torsional rigidity of a vehicle allows the suspension to work more efficiently and predictably. Vehicles with high torsional rigidity will see more travel in the suspension, as the chassis isn’t moving. Considering the suspension uses dampers and the chassis doesn’t, it makes sense why you want the suspension to move and not the chassis.
