I just acquired a 2010 R1200GS 30th Anniversary. It has all the goodies except TPM (tire pressure monitor). From what I can tell, it sounds like bikes with the computer are already wired to accept the TPM signal; minus the wheel transmitters and the actual signal receiver module that plugs into the computer.
Has anyone ever looked into adding the OEM TPM after the fact? Is this feasible/practical/cost effective?
