K-Tech Front Fork Linear Performance Springs (435-485-52) (5.2N) (435 x 485) (Pair)

The K-Tech Front Fork Spring 5.2N is engineered for riders who prioritize a plush, responsive front end.

Built to the same exacting standards as K-Tech’s world-championship racing springs, these 5.2N linear springs provide predictable feedback and improved comfort, ensuring your suspension stays active over varied road or trail conditions. 

Manufactured from high-grade Chrome Silicone wire, every spring is cold-coiled, heat-treated, and shot-peened to ensure long-term durability and resistance to "sagging."

The final polished finish significantly reduces internal friction, resulting in a smoother stroke and better sensitivity to small bumps and ripples in the road.
