Stilo Helmet Parts, Electronics & Adapter Cables
Harris Race Radios™ stocks genuine Stilo helmet electronics, speaker and microphone kits, wiring harnesses and adapter cables for New Zealand and Australian motorsport. Our communications specialists can help match the exact helmet model, electronics connector and radio or intercom before you order.
Aaron Harris brings racing and professional race-engineering experience to equipment selection; he is a MotorSport NZ Licence Examiner for licences, not a helmet or racewear certifier. Rex Harris's motorsport communications experience dates from 1975. He is an official New Zealand RSM Approved Radio Certifier with AU ACMA radio-certifier experience, a radio qualification distinct from helmet certification.
