The chassis utilizes authentic 5052 grade aluminium with a tasteful mixture of brushed and satin aluminium surfaces. To withstand the test of time, the chassis incorporates a sturdy magnesium structural brace while metal surfaces are treated with a deep anodised coating enhancing abrasion resistance.
