If you want to cross reference parts between the NX5/NXA models have a look at the site below.
Click on the parts list tab and list of bikes will appear! Click on your chosen bike for breakdown of all parts for that bike. Amazing!

On the other hand, are you fitting a Bora radiator to your RS, the one with the cut out for the airbox? If so, two out of the three standard NX5/NXA water hoses will not fit, they are too short!
Ask me how I know... It can be sorted though.
