The pressure inside the crankcase, which impedes piston movement, is removed through breather pipes in various places in the engine, reducing power loss and temperature rise inside the crankcase.

At the same time, the oil that escapes is securely received by the catch tank, and only the pressure is released into the atmosphere. This is a standard tuning part for 4-stroke engines.

●Uses an aluminum carbon-wrapped catch tank bottle. The bottle cap is machined from aluminum and has an anodized finish.

　Outer diameter x bottle length: φ63 x 115mm Capacity: 220cc
