bm r80g/s speedos....not a bullet proof part,
trip usually fails pretty early on,(5 off)
main speedo lasts ok ?
i have fitted a sigma targa M(latest version of targa titan)which has larger main speed figures,
the sigma reading "seem"to lag behind the bmw speedo until a constant speed is reached,
the sigma calibration figures don't "agree" with the bm speedo , but easily altered to suit...but who is right?
best checked with a gps?
overall,a neat bit of kit,clock and km/miles
back up for not big money
