The RAM Mounts B-309-1U is a brake or clutch reservoir mounting base designed to attach navigation devices, smartphones, or action cameras to motorcycle handlebars via the master cylinder reservoir. Unlike traditional handlebar clamps that require bar space, this mounting solution uses the existing reservoir as an anchor point, featuring a 1″ diameter ball that integrates with RAM’s modular socket arm system for vibration-resistant device positioning.

Key Features
Space-Saving Reservoir Mount: Utilizes the brake or clutch master cylinder reservoir as a mounting point, leaving handlebar space free for controls and grips without requiring clamps that compete for bar real estate.
1″ Ball Integration: Features RAM’s standard 1″ diameter ball that connects to any RAM socket arm, allowing 360-degree rotation and multi-angle adjustment for optimal viewing angles of mounted devices.
U-Bolt Clamp Design: Secure U-bolt attachment system wraps around the reservoir body, distributing clamping force evenly to prevent damage to the reservoir while maintaining a firm hold during vibration and rough road conditions.
High-Strength Composite Construction: Engineered from marine-grade materials that resist UV degradation, temperature extremes, and road chemicals while providing vibration dampening that protects mounted electronics from handlebar buzz.
Use Case Scenarios
- Mounting smartphone navigation on adventure bikes where handlebar space is occupied by hand guards, heated grips, and clutch levers, using the reservoir as an alternative anchor point
- Installing action cameras for first-person riding footage on sport bikes with clip-on handlebars that lack traditional mounting space near the triple clamp
- Positioning GPS units on touring motorcycles with crowded handlebars, placing the device closer to the rider’s line of sight without obstructing instrument clusters or controls
Why Choose the RAM B-309-1U?
- Solves handlebar space limitations on bikes with hand guards, heated grips, or accessory switches by using the reservoir as a mounting point
- Integrates seamlessly with RAM’s modular ecosystem – pair with any RAM 1″ socket arm and device cradle for custom configurations
- High-strength composite material dampens vibration better than metal mounts, reducing camera blur and screen readability issues during riding
- U-bolt design allows installation without removing reservoir from motorcycle, enabling quick setup and removal for multi-bike use
Pros & Considerations
Pros:
- Frees up handlebar space while providing a secure, vibration-resistant mounting location
- Compatible with all RAM 1″ ball accessories, creating a modular system that adapts to different devices without replacing the base
- Composite construction provides superior vibration dampening compared to all-metal mounts, protecting device screens and camera stabilization
Considerations:
- Requires sufficient clearance around the brake or clutch reservoir – not compatible with motorcycles that have shrouded reservoirs or tight fairing gaps
- U-bolt size must match reservoir diameter – verify your reservoir body diameter before purchase as this mount fits standard round reservoirs, not rectangular or integrated types
Frequently Asked Questions
Q: Which reservoir should I mount this to – brake or clutch side?
A: Mount to the side that provides better viewing angle and clearance. Right-side brake reservoir placement is common for navigation as it’s closer to the rider’s natural sight line, while left-side clutch mounting works better if your brake side has fairing interference or if you prefer the device away from the throttle hand.
Q: What devices can I mount with this ball base?
A: Any device that uses RAM 1″ socket arms and cradles – smartphones, GPS units (Garmin, TomTom), action cameras (GoPro with RAM adapter), or smaller tablets. You’ll need to purchase a compatible RAM socket arm and device-specific cradle separately to complete the mounting system.
Q: Will this damage my motorcycle’s brake or clutch reservoir?
A: No, when properly installed with appropriate torque, the U-bolt distributes pressure evenly around the reservoir body. RAM’s composite material is softer than metal reservoirs, preventing scratching. Avoid over-tightening and ensure the U-bolt matches your reservoir diameter for safe installation.
Q: Can I use this mount on motorcycles with aftermarket reservoirs?
A: Yes, as long as the aftermarket reservoir has a round cylindrical body that the U-bolt can wrap around. It will not work with rectangular reservoirs or integrated reservoir designs found on some sport bikes where the reservoir is molded into the master cylinder body.
Q: How do I prevent vibration blur on cameras or navigation screens?
A: RAM’s composite ball base already provides vibration dampening. For additional isolation, use a RAM socket arm with their X-Grip or cradle systems that feature rubber retention grips, and ensure all ball-socket connections are tightened firmly. For cameras, enable electronic image stabilization if available.
