The Lowbrow Customs Solo Seat Pivot is made right here in Cleveland, Ohio. Heavy-duty steel black powder coated for a beautiful finish paired with custom-made, chrome plated mounting hardware and a specially designed aluminum pivot block. This pivot block is designed specifically for 1963 to 1970 Triumph motorcycles. The pivot block bolts to the stock rear gas tank mount on the frame. Simply tap the stock hole to 5/16-24 fine thread and use the supplied allen bolt, or leave the threads as-is (5/16-26 whitworth) and supply your own bolt. The beauty of this design is that you can use it with a custom gas tank, or with a stock Triumph gas tank by putting it in place of the stock, top rubber washer. The design of this solo seat pivot is such that it allows your seat to sit down nice and low to your frame’s backbone, tucking it in nice and tight. Pair this with your choice of solo seat, solo seat weld-on spring mounts and a pair of seat springs and you can have your seat mounted quickly, easily and professionally! Made in the USA.
