Point

With the newest technology of MAX IV into PV36 can make the drive fast and comfortable. We have set the goal of MAX IV to have both driving performance and comfort. Therefore HKS has analyzed and test the transient characteristic, not the general pin point so we could develop the suspension that has firmness and still comfortable damping feeling. For this result we have redesigned needle and developed variant port system that greatly improved the damping characteristic of driving feeling at a low speed.
For PV36, stiff feeling of stock has improved, and luxurious handling by reducing the big behavior change.
 
・Front fender and tire could interfere with each other in a certain driving condition and the size of the tire or wheel.
・Both front and back's body and upper arm can interfere with each other if you reduce length of the case to the lower limit value of driving.
