Well, the tpm and tool arrived. So far, about $22.00. While examining the tpm, I noticed something very odd. The brand name “Schrader” was on it. Schrader is also the brand on the receiver on the bike. The TPM appears to be identical in every way to the $225.00 item in the parts fische. There were complaints from some members of the BMW MOA forum about buying high priced bearings from the dealer with BMW on the box and CHINA on the bearing. I can only assume that our over priced high quality, German made motorcycles are assembled with Chinese parts, as are some of the F series bikes. Rant over.
