In this study, we define the X-torque curves, $$X-$$
X
-
equilibrium curves, X-moment conservative curves, $$X-$$
X
-
gyroscopic curves as new curves derived from a regular space curve by using the Frenet vectors of a space curve and its position vector, where $$X\in \left\{ T\left( s\right) , N\left( s\right) , B\left( s\right) \right\} $$
X

N

B

and we examine these curves and we give their properties.
