K-MAN FM58-A (International Edition)

The latest FM-58 nitrogen Damper (Full-Terrain Multifunctional 58mm Diameter Damper) is the third-generation product of K-MAN Suspension. Very clear target we set for the new shocks based on our rich developing experiences and feedback from the market and customers of previously two generations, which is to give perfect balance between comfort and handling in off-road, to ensure the driving experience in full-terrain condition, we define it as: FM-58 (International Edition). The new force curves of K-MAN FM-58 nitrogen damper has been greatly upgraded. Force was set positively correlated with the piston displacement speed. The damper provides small force to give comfort riding at low piston displacement, while it generated firm force in off-road when piston displacement at high speed to give good handling. The new FM-58 structure realized firm and comfort characteristics at same time.
