Product Information

Overview

Your motorcycle rides on rubber tires for grip and to soften the ride. Why should it be any different for your mounted electronics? With RAM's patented rubber ball and socket technology, the turn of a single knob grips the adjustment arm to a rubber ball designed to dampen shock and vibration. With RAM products, it's all grip and no slip plus protection for your valuable electronics. Simply place our easy to install ball base onto the motorcycle handlebar top clamp and you're done. After that, a world of mounting possibilities just opened up. The round base contains a 1" diameter rubber ball connected to a flat 2.5" diameter base. This mount has pre-drilled holes, including the universal AMPS hole pattern.

RAM® Handlebar Clamp Mount with M8 Bolts and Round Plate - Medium

Every RAM® mount is built around a rubber ball and socket system. The ball size sets how much weight the mount can carry. Match it to your device for smooth adjustment with a rock-solid hold.

RAM Mounts ball size specifications and typical uses
Size	Ball Diameter	Max Load*	Best For
A	0.56" (14.3 mm)	0.5 lb	Action cameras and other ultra-light devices
B — this product	1" (25.4 mm)	2 lbs	Phones, GPS units, and small tablets — the most common size
C	1.5" (38.1 mm)	4 lbs	Large tablets, fish finders, and rougher rides
D	2.25" (57.2 mm)	6 lbs	Rugged tablets, laptops, and heavy equipment
E	3.38" (85.9 mm)	15 lbs	Large displays and demanding aviation or industrial use

*Approximate capacity for a standard ball with a mid-length arm. Shorter arms and steel-reinforced posts increase real-world capacity.

Reading part numbers

The letter after RAM tells you the ball size: RAM-B-166 uses a 1" B ball, while RAM-D-201 uses a 2.25" D ball. C size parts are the exception and carry no letter, so RAM-201U is a C size arm.

Short, medium, and long double socket arms compared side by side. This product uses a Medium arm — Arm lengths

The double socket arm clamps over two balls — one on the base and one on your device holder. Arm length sets your reach: short arms are the most stable, while longer arms give you more freedom to position the device.
