In the item 11204000 is indicated the dimension 39x21x10mm and compatibility with Vespa 50 Special V5B1T. I've disassembled the silentblock from the motor of my V5B1T, and the dimension is: -internal diameter 20mm -external diameter 39mm -thinkness 25mm
Then, this article is not correct?
The alternative is the item 11220400, but is different!
