Original throttle slide diaphragm for the Mikuni BDST 38 carburetors as used on, amongst others, the Ducati 600 SS SuperSport (1994-2000).
Mikuni part number: N213008
Please note that this is the diaphragm only.
We can also supply the complete slide which can be found HERE.
Although these carburetors were originally delivered on the above mentioned models of motorcycles, they are often transplanted onto other bikes and engines so the range that these diaphragms might fit is much broader.
Alternatively, your bike might have been equipped with different carburettors during its life so please verify that the diaphragm shown will fit your bike.
