Bell Replacement Adjustable Microphone Kit for HP10 / Mag-10 Rally Helmets

Bell 2081829 Adjustable Single Microphone Kit — HP10 & MAG-10 Rally

Manufacturer part reference: 2081829. Bell identifies this as the adjustable single microphone kit for the half-chin-bar arrangement on relevant HP10 and MAG-10 rally helmets. Match the exact helmet generation, existing microphone assembly and supplied kit components before ordering.

Positioning and Installation

Bell’s instructions describe a telescopic rubber positioning mechanism with three levels: 16 mm, 23 mm and 30 mm. Position the microphone directly in front of your mouth, no more than 5 mm from your lips, following the instructions for the exact installation.

Bell provides different installation sequences for older cone-style assemblies and newer telescopic assemblies. Identify the existing arrangement before removal, use the appropriate Velcro mounting sequence and check the complete intercom after fitting. Do not substitute instructions for the earlier separate-spacer kit.

Why Keep a Spare?

Microphones are consumable items in motorsport — subject to sweat, vibration, and impact. A correctly matched spare can reduce downtime, but test the complete helmet and intercom before the event rather than assuming a spare guarantees uninterrupted communications.

Frequently asked questions

Will this microphone fit every HP10 or MAG-10 helmet?

Confirm the exact rally helmet generation, microphone reference, mounting provision and electronics before ordering. The family name alone does not establish fit.

Will a matching connector guarantee microphone compatibility?

Match the microphone type, connector pinout, amplifier, cable and speaker or earpiece arrangement. A physically matching Nexus connector alone does not establish electrical or audio compatibility.

Why does microphone position matter?

Correct microphone-to-mouth position helps clear speech in a noisy car. Set it according to the manufacturer’s instructions, check the cable routing and test the complete intercom before an event.
