S&S Cycle Breather Gears

Overview

S&S Cycle Breather Bears are essential parts that prevent the crankcase pressure from spilling engine oil all over you. These parts have an all steel construction for maximum dimensional stability and abrasion. The strength of these accessories helps them withstand rough handling making them durable and long lasting. They have a flawless finish that gives them a quality look and feel. These motorcycle breather gears are custom made for your bike and therefore fit perfectly without modifications. Just like most other aftermarket parts by S&S Cycle, the breather gears are thoroughly tested to ensure they beat the tough operating environments most performance bikes are ridden in.
