The S660 has already set a low height on STD, so if you lower it down more than necessary, it will sacrifice the stroke.

Therefore, SPOON has developed a low -down spring that does not sacrifice the stroke and further improves the S660’s high -turn ability within the security standards.

Although the cornering performance and straight stability have improved, you can enjoy a wide range of riding a sense of push -ups from town riding to winding and sports driving.
