Our swivel hitch gives you the peace of mind needed while carrying a trailer behind your motorcycle. Leaning into a turn is a necessary (and fun) part of riding a motorcycle. Sadly, when towing a trailer, traditional couplers do not allow the appreciable lean needed in a turn, which can cause flipping, binding, or jack-knifing. To help avoid these potentially deadly situations, industry insiders (Read Article Here) strongly advise the use of a swivel coupler, and we agree. Our swivel hitch provides a 360 degree swivel that gives your bike the ability to lean on turns, and provides an element of safety and performance. The swivel hitch coupler is constructed of steel, has a high tensile steel rod and has a black finish. * Includes both swivel and coupler Note: This fits a tongue with an inside measurement of at least 2 1/8" x 1 9/16". Before purchasing, please review the 2nd photo and ensure that this product will mount inside the tongue of your trailer.
