RAM MOUNTS Motorcycle Handlebar U-Bolt Mount — B Size 1" Ball, Marine-Grade Aluminium, Fully Adjustable

This U-bolt mount is engineered to fasten to handlebars, roll cages, or any round rail and serve as the foundation for RAM's ball-and-socket mounting system. It pairs a zinc-coated U-bolt base with a powder-coated aluminum cradle and a standard B-size 1" rubber ball, which accepts all B-series RAM components. Built for rugged outdoor use, the assembly comes with protective end caps and is covered by RAM MOUNTS' lifetime warranty.

How does this mount attach to my motorcycle handlebar?

The mount uses a zinc-coated metal U-bolt that wraps around round rails and secures to a powder-coated aluminum base plate. Once tightened, the 1" B-size rubber ball faces outward at a right angle to the rail, ready to accept any B-series socket arm.

• Zinc-coated U-bolt fits a range of rail diameters and resists corrosion.
• Powder-coated aluminum base provides a sturdy mounting surface.
• Includes black cover caps to shield exposed U-bolt ends from weather.

What devices and RAM components are compatible with the B-size 1" ball?

The 1" B ball is a common RAM standard that interfaces with any B-series cradle, arm, or adapter. This lets you mix-and-match phone cradles, GPS holders, camera mounts, and extension arms to build the exact setup you need.

• Works with all RAM B-series sockets and cradles.
• Accepts short or long socket arms for customized reach and angle.
• Supports accessory mounts for phones, GPS units, action cameras, and small tablets (with compatible cradles).

Will this mount hold up in harsh weather and on rough roads?

Yes—materials and finish are selected for outdoor durability. The U-bolt is zinc-coated to resist rust, while the base is powder-coated, marine-grade aluminum built to withstand vibration, moisture, and repeated use.

• Marine-grade aluminum resists corrosion and structural fatigue.
• Rubber ball offers secure clamping with shock-damping properties.
• Lifetime warranty from RAM MOUNTS covers manufacturing defects.

How adjustable is the ball-and-socket joint once installed?

The B ball and socket system provides near-infinite adjustability in pitch, yaw, and rotation when the socket is loosened. Tightening the socket locks the device securely in the chosen orientation, allowing precise positioning and repeatable placement.

• Ball-and-socket design enables fine-angle adjustments for glare-free viewing.
• Locking torque is controlled by the socket component you choose.
• Multiple arm lengths and socket types allow elevation and extension options.

Who this is for: Motorcyclists, off-road riders, and anyone who needs a dependable, adjustable mounting point on a round rail will benefit from this RAM MOUNTS U-bolt mount. It's ideal for riders who want a modular system—attach a phone cradle for navigation, add a camera mount for recording rides, or combine arms and adapters for specialized setups. If you want a corrosion-resistant clamp with a standard 1" B ball that works with RAM's extensive accessory lineup, this mount provides a robust, serviceable solution backed by a lifetime warranty.
