These MOTON 65 Series helper springs are flat wire springs with a 65mm open length, offered in 51mm, 61mm, 64mm and 75mm inside diameters. The flat-section wire lets each spring compress to a very small block height, which frees up more of the damper's usable stroke. MOTON says the helper also keeps the main spring seated in its perch when the suspension is fully extended, at full droop. They suit coilover set-ups that need maximum travel.
