Having trouble finding the perfect mirror for your Triumph Motorcycle? Now you can mount most aftermarket mirrors onto your America, Speedmaster, Rocket III or Bonneville with ease! British Customs has designed an adapter that raises the mirror mounting point above the awkward control hump, seating them properly for a snug fit, to allow most aftermarket mirrors to fit your Triumph Motorcycle. The adapters are machined from stainless steel and include stainless steel mounting hardware for superior weather resistance.
