If you need a replacement cap for your Acerbis tank, why not go bling? These caps have a carbon fiber pattern molded into them that is extremely realistic. Looks like the real thing. Topping off the cap is a CNC Machined metal vent cap. This eliminates the need for a lengthy vent tube that gets in the way. The vent cap allows air to vent into the tank but does not allow fuel to splash out during normal use or during a tip over.

  These caps fit Acerbis tanks only.
