The heat sink effect can be expected to cool the engine. The genuine product's fins are oriented vertically, disregarding the flow of air while riding, but this product is designed to actively utilize the airflow while riding. Higher-end models have additional top heat dissipation fins to further enhance the heat dissipation effect.
You can feel that the engine temperature rise is suppressed more than with the genuine product when cruising under high load. It's excellent not only in terms of fashion but also in terms of function. The main body is made of machined aluminum, giving it a luxurious feel.
