Filterskins are an extremely thin but durable air filter cover. While allowing maximum airflow, an oiled Filterskin will catch 90% of the dirt that tries to pass through the air filter. Between races or between rides, simply pulling off a dirty Filterskin and sliding on a clean one can save you time and actually save money on expensive solvents and oils. Filterskins are extremely elastic and each size will expand over a wide range of air filter sizes, this size fits the "late" Beta air filter used on 2013-on RR, 2014-on RS, and X-Trainer.
Note: Because of the shape of the Beta filter (late), these work best when installed around the sealing edge of the filter before installation.
