This RSI Racing tether mount is a powder-coated aluminum plate made specifically for the Polaris RMK steering stem, giving the updated large factory Polaris tether a secure, seamless home on your sled. It fits Polaris 650, 850, 900R, and Boost models, so riders running those engines can mount the tether cleanly instead of improvising.

The aluminum build and powder-coated finish are there to hold up to season after season of snow and vibration, and the RMK-specific shape means the plate sits snug against the stem rather than floating or flexing. If you ride a Matryx or AXYS RMK and want the factory tether mounted the way it was meant to be, this is the piece that does it.
