The voltage regulator of the F650 is known to fail and when it does, the bike runs poorly, sputters and won't get out of its own way. This is a top quality replacement part. It is a direct replacement and installation will take only a few minutes.
Perfect fit, high quality and in form and function identical to the original part.
Equivalent to the BMW part number 61 31 2 346 432
For F650 Funduro and F650 ST
