This 6063 term relates to the type of aluminium alloy, and this specification is known for corrosion resistance, and capacity for a high quality surface finish. Indeed the intricate detailing looks sublime and premium, but it has an added purpose.
Aluminium is known for greater thermal transfer properties, i.e the ability to disperse heat. Given that higher power lights produce more heat, and a buildup of that heat can damage the battery, having a greater capacity to disperse that heat is vital. Add to that the machined gills which increase the surface area for greater heat transfer; form and function beautifully blended into one.
Other external features include the protruding lip over the light to reduce glare for both the rider and other…
