Greetings. I have a 2007 R1200RT early model and the final drive has only one drain point at the 9 o'clock position. The later models and onward onward have a bottom 6 o'clock drain point. In this manner there is no need to remove the wheel and drop the FD to drain the fluid.

I've noticed a number of police bikes out there being parted out. Will a 2008 or 2009 FD unit with a bottom port swap out with my 2007 unit without changing anything else or gear ratio worries?

Thanks for the input.
