Sena B20 Clamp Kit

The Sena B20 Clamp Kit is a helmet mounting accessory designed for Sena 20S and 20S EVO Bluetooth communication systems. Unlike adhesive-based mounts, this clamp kit uses a secure mechanical attachment that grips the helmet shell without permanent bonding, making it ideal for riders who frequently switch helmets or prefer non-adhesive mounting solutions.

Technical Specifications

Key Features

Non-Adhesive Installation: Mechanical clamp design eliminates the need for adhesive pads, preserving your helmet’s finish and allowing easy removal without residue.

Multi-Helmet Compatibility: Quickly transfer your Sena 20S unit between multiple helmets by installing clamp kits on each, saving time compared to re-positioning adhesive mounts.

Secure Attachment: Clamp mechanism provides firm grip on helmet shell, maintaining stability even during high-speed riding or off-road vibrations.

OEM Sena Quality: Genuine Sena replacement part engineered to the same specifications as factory-installed clamp mounts.

Use Case Scenarios

• Riders who own multiple helmets and want to share one Sena 20S unit across different lids without buying multiple communicators
• Track day enthusiasts who switch between street and racing helmets and need quick device transfer capability
• Replacement for damaged or lost original clamp components from Sena 20S packaging

Why Choose the B20 Clamp Kit?

• Preserves helmet integrity – no adhesive residue or surface modification required for installation
• Tool-free mounting system allows device attachment and removal in seconds
• Designed specifically for Sena 20S architecture, ensuring perfect fit and alignment
• Cost-effective solution for multi-helmet setups compared to purchasing additional complete Sena units

Pros & Considerations

Pros:

• Completely reversible installation – remove clamp without leaving marks on helmet shell
• Faster helmet switching than re-positioning adhesive mounts
• Genuine Sena component ensures compatibility and durability

Considerations:

• Only compatible with Sena 20S and 20S EVO models – does not fit 30K, 50S, or other Sena series
• Clamp profile may sit slightly higher on helmet surface compared to low-profile adhesive mounts

Frequently Asked Questions

Q: Will this clamp kit work with Sena 30K or 50S models?

A: No, the B20 Clamp Kit is engineered exclusively for Sena 20S and 20S EVO units. The 30K and 50S series use different mounting architectures and require their respective clamp kits.

Q: How do I install the clamp kit on my helmet?

A: Position the clamp bracket on the helmet shell where you want the unit located, typically on the left side. Insert the mounting plate between the helmet shell and EPS liner, then tighten the clamp screw until secure. The Sena 20S unit then slides onto the installed clamp base.

Q: Can I use this on carbon fiber or fiberglass helmets?

A: Yes, the clamp design works on full-face, modular, and open-face helmets with sufficient shell thickness for the clamp to grip. Ensure the clamp does not compress internal EPS foam during installation.

Q: Is the clamp as secure as the adhesive mount during high-speed riding?

A: When properly installed, the clamp provides equivalent security to adhesive mounts. The mechanical grip resists vibration and wind force effectively at highway speeds and beyond.

Q: Does this kit include the Sena 20S main unit or just the mounting hardware?

A: This is a mounting accessory only – it includes the clamp bracket, plate, and hardware but does not include the Sena 20S Bluetooth unit itself. You must already own a Sena 20S or 20S EVO communicator.
