M-stream reed valve system. YAMAHA YZ65. Black.
Art.nr.: 120116Z
This diaphragm is made entirely of aluminum. Unlike the original, which is made of synthetic material and prone to leaking due to deformation, this diaphragm ensures a perfect seal—even as the engine heats up. This results in significantly more power in the low and mid-range RPMs.
