There are very subtle differences, but a lot can be interchanged given time and facilities. However, not much is a direct bolt-on replacement, and the later the NF5 the less interchangeable parts are with an NSR.

Front wheel is very easy. Axle size is the same, spacers are similar (will need to mix'n'match NSR and RS spacers depending on the wheel, but all OEM parts can be used), and the disc PCD is the same, however the later NF5s (1989~ I think) uses a larger 296mm disc.

Rear wheel will need fiddling with, but it will go. Axle size, once again, is the same as the RS. You just need to get the chain run and rear disc correct.
