question on calibration of R-bike speedometer

Postby jskene » Thu Jun 12, 2003 9:56 pm

Can the speedometer of an R1100 be adjusted? I have doen this on a K-bike, but I'm not sure if the R-bikes have the same speedo.

Thanks;

R-bike speedo

Not sure. I just bought a Sigma-BC 800 bicycle computer. That gives me some additional features and is much more accurate. I have yet to discover the top end of the Sigma's speedo (I have heard it is up in the 120s or 130s).

It is a totally different speedo cluster - cable-driven instead of electronic - but I think the speedometr needle itself can be calibrated by some adept person.

However, if you have a similar discrepancy in the odometer you may be able to correct them together by changing the speedometer drive unit. The R1100GS is WAY off, typically, and becomes very close when the R1100R 2.875:1 drive is used in place of the original 3.0:1 drive. If you're on an RS or RT, then there aren't any options here. :(

All of these are interchangeable and cost about $40:
R1100GS: 3.0:1
R1100R: 2.875:1
R1100RS/RT: 2.6:1

If thee odometer is wrong, you should correct it first and then see what the speedo is doing.
