Key Features
Wide Clamp Range for Oversized Bars: Accommodates bars from 1.87″ to 3″ diameter, fitting thick cruiser handlebars, adventure bike crash bars, and custom builds with oversized tubing that smaller clamps cannot grip.
Rubber-Lined Claw Grips: High-density rubber pads line the claw opening to protect painted and chrome finishes while providing superior grip that resists rotation under vibration and road shock.
Marine-Grade Aluminum Construction: Powder-coated aluminum body withstands exposure to rain, salt spray, and temperature extremes without corroding or weakening over thousands of kilometers.
Tool-Adjustable Security: Hex bolt tightening mechanism allows riders to dial in precise clamping force – tight enough for vibration resistance, gentle enough to avoid crushing handlebars or leaving marks.
Use Case Scenarios
- Mounting GPS units or smartphones on adventure bikes with large-diameter crash bars or auxiliary light bars
- Installing action cameras on cruiser highway pegs or forward control bars for unique camera angles
- Attaching device mounts to custom motorcycle builds with oversized 1.5″ to 3″ handlebar tubing
Why Choose the RAM Tough-Claw Large?
- Only RAM clamp that accommodates truly oversized bars beyond 2″ diameter that standard clamps cannot grip
- No-drill installation preserves resale value and allows repositioning as needs change
- Proven in marine and powersports environments where vibration and weather exposure destroy lesser clamps
- Backed by RAM Mounts’ lifetime warranty against manufacturing defects
Pros & Considerations
Pros:
- Fits crash bars and auxiliary bars that are too thick for standard handlebar mounts
- Rubber padding prevents scratching chrome or powder-coated finishes on custom bikes
- Can be installed and removed without tools in minutes once initially adjusted
Considerations:
- Large physical size may interfere with controls or cables on compact bikes – verify clearance before purchase
- Requires bar diameter between 1.87″ and 3″ – too large for standard 7/8″ or 1″ handlebars (use small or medium Tough-Claw instead)
Frequently Asked Questions
Q: What handlebar diameter do I need for the Large Tough-Claw?
A: Your bar must measure between 1.87″ (47.5mm) and 3″ (76mm) in diameter where you plan to mount the clamp. Standard motorcycle handlebars are 7/8″ or 1″ – this large clamp is for oversized bars only. Measure your bar with calipers or a tape measure before ordering.
Q: Will this clamp damage chrome or painted handlebars?
A: No. The claw features non-marring rubber pads that distribute clamping pressure evenly without scratching chrome, powder coat, or anodized finishes. Proper tightening according to RAM specifications will not damage bars.
Q: Can I mount this clamp vertically on round crash bars?
A: Yes. The claw clamps securely to round tubing in any orientation – horizontal, vertical, or angled. The rubber grip pads and hex bolt tightening prevent rotation even when mounted to vertical or diagonal bars.
Q: How much torque should I apply to the clamping bolt?
A: RAM recommends hand-tightening with a hex key until the clamp feels snug and does not rotate when twisted by hand. Over-tightening can deform the rubber pads or, in extreme cases, crush thin-walled tubing. For high-vibration applications, check tightness every few hundred kilometers.
Q: What’s the difference between Tough-Claw Small, Medium, and Large?
A: The difference is clamp diameter range. Small fits 0.625″ to 1.5″ bars, Medium fits 1″ to 2.25″ bars, and Large (this model) fits 1.87″ to 3″ bars. Choose based on your actual bar diameter. There is overlap in the ranges, but using the correct size ensures optimal clamping performance.
