Motorcycle Handlebar Clamp Base with M8 Bolts

RAM® M8 Handlebar Bolt Ball Base — Clean Install, Rock-Solid Mount

The RAM® M8 handlebar bolt base replaces your existing M8 bolt with a 1” B-size rubber ball, giving you a clean, factory-style mounting point right on the bars. No clamps. No clutter. Just a solid foundation for your RAM® setup.

Designed to absorb shock and vibration, the rubber ball protects your electronics while keeping everything locked in place. Pair it with any B-size RAM® double socket arm and device holder to dial in your perfect viewing angle.

Machined from marine-grade aluminum, it’s built to handle vibration, weather, and long miles—on road or off.
