Point

More advanced version of very famous HIPERMAX III Sport09 which supported many records in the circuit racing.
We have tested in circuit as well as the street and could have improved stability of rear which HIPERMAX III Sport09 lacked a little. Therefore rear tires have better grounding and roll stiffness which results in improved rear traction and absorption at a high speed driving. Once you experience the new MAX IV SP, we are sure that you can feel the difference from the Sport09.
However we also set for a comfortable ride in the street.
MAX IV SP is the perfect for the circuit and high speed driving.
