Beta SINCRO after market airbox rubber flap. This is designed to keep mud from entering the SINCRO airbox much better than the standard item. Wider and longer it does a great job of preventing mud and water getting where it shouldn't!! Also thicker making it much longer lasting! A must have for big trials such as SSDT and a very handy addition to any SINCRO! A direct replacement for the std. item and very easy to fit!!

Stops mud getting between the airbox and exhaust silencer helping prevent dirt from entering the air filter and electrics area!
