The GPRV4 stabilizer gives Honda MSX125 Grom riders 20 levels of damping, all selected by a turn of the large, no-slip dial that is easy to use, even with gloves on. The GPRV4 is available in eight color options, and it mounts easily to the top of the triple clamp with no drilling required. The GPRV4’s MSRP is $495.
