This is the standard size for Piaggio scooter rear bearings and fits my Scarabeo and Vespa models as expected. The lager seems to be of decent quality - while I'm no lager expert, I've seen some really crappy lagers and this one isn't one of them - but its provenance is hard to pinpoint. It was packaged in a Timken box and had a holographic Timken logo sticker on the inner plastic bag. The stock seal says "Japan" as shown here, but another sticker on the box says "Made in China" and in Chinese letters. It's not clear from my online research if Timken makes bearings in China, if they outsource some of the bearing production to China under the Timken brand, or if it's just a fake. The embossing of "Japan" on the seal makes this situation even more confusing. So I have no idea what quality to expect from this product. I invite the seller "bearings1988" to China to clarify what's going on.
