The radiator guard is made of aircraft-grade aluminium sheet. It is critical to prevent long-term fin damage of your radiator, ideally to be used by riders who occasionally ride on dusty or gravel roads. But in the long term, riding on the road prevents damage from stone or pebble debris. This unit efficiently radiates heat away from the radiator, also sidebyside protecting it from minor damages that may be unseen in the long run. Powder coated in black and comes with a lifelong warranty against any rusting whatsoever.
