RAM Mounts Torque™ Large Rail Base – B Size

The RAM Mounts Torque™ Large Rail Base – B Size is a heavy-duty mounting base designed to clamp onto large-diameter round rails and tubes between 1.125 inches and 1.5 inches. This size range specifically accommodates oversized crash bars, engine guards, and frame tubes common on adventure motorcycles, touring bikes, and larger displacement cruisers. The Torque system’s non-marring rubber strap grips these larger tubes without scratching powder-coated or painted finishes, while the integrated 1-inch B Size ball socket provides compatibility with RAM’s extensive range of arms and device holders.

Technical Specifications

Key Features

Large Diameter Compatibility: Specifically engineered for oversized rails from 1.125″ to 1.5″ diameter, fitting the heavy-duty crash bars and engine guards on adventure bikes like BMW GS series, Triumph Tigers, and large-displacement cruisers where standard mounts are too small.

Non-Marring Rubber Torque System: Proprietary rubber strap with molded grip teeth creates secure clamping force on large tubes without scratching powder-coated crash bars or painted frame rails, protecting the finish on expensive adventure bike protection systems.

1-Inch B Size Ball Socket: Despite the large base size, uses the standard 1-inch ball size for compatibility with RAM’s widest selection of arms and holders, from smartphone mounts to GPS units and action cameras.

Reinforced Construction: Larger base platform and extended rubber strap provide the increased clamping force needed to secure mounts on oversized tubes while maintaining the tool-free installation convenience of smaller Torque bases.

Use Case Scenarios

• Mounting GPS navigation to oversized crash bars on adventure motorcycles like BMW R1250GS or Triumph Tiger 900 for long-distance touring without scratching expensive protection equipment
• Installing smartphone mounts on large-diameter engine guards on cruisers like Harley-Davidson or Indian motorcycles where standard handlebar mounts won’t fit
• Attaching action cameras to frame tubes on adventure bikes for ride documentation, positioned away from handlebars for wider field of view without vibration

Why Choose the RAM Mounts Torque™ Large Rail Base – B Size?

• Specifically sized for adventure bike crash bars and cruiser engine guards that are too large for standard handlebar mounts, eliminating the need for adapter shims or makeshift solutions
• Rubber strap protects the powder-coated finish on expensive SW-MOTECH, Heed, Touratech, and OEM crash bars that cost thousands of rupees and would show permanent scratches from metal clamps
• Positions mounts on crash bars lower and wider than handlebar mounting, providing better viewing angles for GPS navigation and reducing vibration from handlebar-mounted devices
• Despite large base size, maintains compatibility with standard 1-inch B Size RAM ecosystem, allowing use of the same arms and holders you may already own from previous bikes

Pros & Considerations

Pros:

• Fits oversized 1.125″ to 1.5″ crash bars and engine guards on adventure bikes and cruisers where standard mounts are too small
• Non-marring rubber protects powder-coated crash bar finishes from scratches and corrosion initiation points
• Tool-free installation allows repositioning or removal without disassembling luggage or fairings to access tools

Considerations:

• Only fits large-diameter rails from 1.125″ to 1.5″ – will not fit standard 7/8″ handlebars or smaller crash bars (use Medium or Small Torque base for those applications)
• Larger base footprint may interfere with luggage mounting points or passenger footpegs on some bikes – verify clearance before purchase if mounting near other accessories

Frequently Asked Questions

Q: How do I know if my crash bars need the Large size Torque base?

A: Measure your crash bar or engine guard diameter with calipers or a ruler. If the tube measures between 1.125 inches (28.6mm) and 1.5 inches (38.1mm), you need this Large base. Adventure bike crash bars typically fall in this range, while standard handlebars use the Medium (3/4″-1″) size.

Q: Will this base fit BMW GS crash bars?

A: Yes, most BMW GS series crash bars (including aftermarket options from SW-MOTECH, Touratech, Hepco & Becker) use tube diameters in the 1.125″ to 1.5″ range that this Large Torque base accommodates. Always verify your specific crash bar diameter to confirm.

Q: Can I mount heavy devices like tablets on this base?

A: The Large Torque base provides secure clamping for the base itself, but total weight capacity depends on the RAM arm length and ball size you use. The 1-inch B Size ball is rated for medium-duty applications like smartphones and standard GPS units. For tablets or very heavy devices, consider upgrading to a C Size (1.5″) or D Size (2.25″) ball base for increased strength.

Q: Does the rubber strap degrade in hot weather or monsoon conditions?

A: RAM Torque rubber straps are formulated for UV and weather resistance, maintaining clamping force in temperatures from freezing to extreme heat. Check and retighten the base after the first 100km of riding as the rubber may settle slightly, then inspect periodically for any cracking or stiffness that would indicate replacement is needed (typically after several years of use).

Q: Can I use this base on square or rectangular crash bars?

A: No, the Torque system is designed specifically for round tubes. The rubber strap conforms to circular profiles but cannot grip flat sides of square bars effectively. For square or rectangular posts, use RAM’s Square Post Clamp bases instead.
