If your BMW R45 or R65 is running rough or bogging down, the carb diaphragms might be the culprit.

This is a set of two replacement membranes for BING carburetors, specifically the 26/28/32 models.

They're made by Boxup in Germany, so you're getting quality that matches the originals.

They cross to OEM part numbers 90155 and 13111254774.

If your old diaphragms are cracked or stretched, swapping these in can bring your bike back to life.

Simple fix, big difference.
