K-Tech Front Fork Linear Performance Springs (36-260-85) (8.5N) (36 x 260) (Pair)

The K-Tech Front Fork Spring 8.5N (36-260-85) is designed to replace restrictive or undersprung OEM components with race-grade precision.

At 8.5N, this spring rate is ideal for lighter riders or those who prioritize a front end that "tracks" the ground perfectly, providing maximum mechanical grip and confidence through the bars.

Manufactured to DIN 2095 Grade 1 standards, these springs are cold-coiled from premium Chrome Silicone wire. K-Tech’s signature manufacturing process—including heat treating, tempering, and shot peening—ensures that the spring maintains its rate and ride height over years of hard use.

The final polished finish significantly reduces internal friction, delivering a smoother, more responsive fork action.
