What We Do That Others Don’t

Helmet-to-Radio Integration

Every Stilo helmet we supply can be configured to work with your existing radio system — whether that’s Motorola MotoTRBO, Kenwood, Rugged Radios, or any other professional system. We supply and fit the correct adapter cables, wiring harnesses, and electronics to ensure your helmet communicates reliably under race conditions. Not sure which radio suits your application? See our NZ Handheld Radio Buying Guide for an independent overview of handheld radio options.

Microphone Setup & Noise Cancellation

Microphone positioning is one of the most overlooked aspects of helmet setup. Incorrect positioning leads to wind noise, engine noise bleed, and poor transmission quality. Our engineers advise on correct boom mic positioning and noise cancellation settings for your specific helmet model and radio system. Read our full communications setup guide →

Intercom System Matching

Not all intercoms are compatible with all Stilo helmet electronics. We match your Stilo helmet to the correct intercom system and supply the correct interface cables and adapters. Stilo intercom manuals →
