Designed for bigger insulated cups, plastic water bottles or even your reliable steel coffee cup, the Level Cup XL keeps your drink upright, regardless of the conditions. This kit includes a short arm and a combination base that attaches to rails or brake/clutch reservoirs on motorcycles and ATVs. The mounting base can accommodate rails from .5″ through 1.25″ and most standard handlebar sizes. The oversized opening cradles the biggest of gulps and the adjustable bottom piece moves up and down to accommodate taller cups. The rubber feet flex to fit various sized cups as well. RAM Mounts has refined the self-leveling action to keep your cups full.
