The RAM motorcycle fork stem base is one of the cleanest and most popular solutions for mounting your favourite device on the center of your bike. Featuring a B size 25.4mm (1″) rubber ball, this part is designed to fit into the cylindrical bore of fork stems and will work with stems that measure 12mm to 38mm (.5” to 1.49”) in diameter. This system utilizes ball and socket connections that can be adjusted to provide a multitude of mounting positions and secured to provide stability during use. It’s made of powder-coated, marine-grade aluminium for durability and reliability in the most demanding environments. Connect the ball to any RAM Holder/Cradle to mount phones, cameras, GPS units and more.
