The Ohlins FKS508 NIX 30 Street Fork Cartridge Front is a front suspension cartridge kit designed for Harley-Davidson Softail models including the Fat Bob, Low Rider S, and Low Rider ST. It is engineered to improve front-end control, feedback, and braking stability for street riding. The damping performance is intended to remain consistent across a range of riding conditions.
