Does anyone know if any other model of vfr400 rear wheel will fit an NC24?
I am looking to take out the 18" and put in a 17" so my Mrs can touch the ground easier.
Any help much appreciated!

The nc24 rear wheel is retained by four nuts while the later nc30 only uses one so I suspect the answer to your question may be a no.The nc24 is a small bike with a low seat height so I am surprised it is still too tall for your mrs.

nothing is going to be straightforward.

Do you have the right size tyre on? 130/70/18?

The NC24 has one of the lowest seat heights of all the 400 sports bikes.. feel likes im climbing a ladder when i get get on the ZXR..

I think you'd be looking at a chopper / cruiser if you wanted anything smaller.

OK thanks for your respective replies
