Swivel Safe — swivel towing coupler for motorcycle trailer hitch

Description

This is a slightly-used Swivel Coupler manufactured by Swivel Safe. It has under 1500 miles, used to tow a 350 pound trailer. Removed it since I tow with an auto, not a bike.
(From the manufacturer’s website)
“The swivel safe design allows for the ultimate experience on a bike. Worried about towing a trailer ruining your style and experience? The swivel safe allows you to keep the thrill of leaning into turns and in fact, is the only proper way to ride. Leaning into turns is essential to ride a motorcycle safely.
Normal hitches restrict movement to 30°. This restriction does not allow riders to lay their motorcycle down in an emergency. While taking turns with a normal hitch the trailer generates upward forces that can affect the stablitly of the rider. Sometimes these forces lead to flipping the trailer and motorcycle.
A swivel safe coupler will allow trailers to stay upright even on the most exterme turns. Because the coupler allows for complete 360° independent movement. Giving riders the freedom to ride restriction free.”
