Speedos

[diggers]

I live in NZ and have just bought an 81 R65, imported from the US.  The speedo is not going and I could get it fixed, but would like to get a metric one (we do metric in NZ!).
Can I simply take off the imperial one and fit the metric one? Or are there expensive/cheap modifications required as well? Also can I fit a speedo from any R series bike?  Or what about K series?  Or does it have to be specific for the R65?
I'm a mechanical ignoramus and this is my first bike at age 45 so would like to find out a few things!

Can anyone help me out here?

First congratulations on buying a great first bike!
good news - you should be able to change to a metric speedometer without changing anything else.
bad news - only an R65 speedometer will fit. the mounting is unlike other airheads and the ratios are unique.
Otherwise if you fit a MPH speedometer you can change your thinking - 62MPH = 100kph, 31 MPH=50 kph. this worked for me when I rode in Europe with a US market R60/2.

Used R65 speedometers do show up occasionally on ebay - rebuilds are available. You could get it fixed and have a metric faceplate installed but the odometer would still read miles.

Hey thanks drewboid!  That's exactly what I wanted to know, cleared up some of the fog in my brain about the topic!  I now know what I'm supposed to be looking for! Cheers
