Yamaha Brake Reservoir Diaphragm 360-25854-01-00

Perfect fit and quality materials in the product!!

Looks xnd fits like OEM.

This product is good and it works but...being that you are fitting it too your old brake reservoir I learned to get the fluid cap to not leaking it really has to sit perfectly square on center to the surface of the master cylinder as you screw on the cap. I believe there is a trick to doing this by feel to get a nice air tight leak free seal of the cap to master cylinder. Took me three tries to get it right. I think maybe if this was just a bit bigger in diameter where it sits on the master cylinder it may have worked on the first try. However it does work and just like the old part in fitment/appearance.

Nice original part ,fits and seals nice.
