A riser for mounting to a rider-support surface of a recreational board and having a binder connected thereto comprises a first plate and a second plate selectively connectable to the first plate along a length of the first plate so as to define a connection location. A plurality of separate and interchangeable dampening members is connectable to each of the first plate and second plate. The plurality of dampening members is spaced along a portion of each first and second plate which is opposite the connection location of the first and second plates. The plurality of dampening members includes a first dampening member and a second dampening member, each having a differing hardness.
