Pretty much Tom. Where an NF5 finishes a NX5 starts. Best I think we had out of Tom's NF5 was 73hp, his NX5 made 74hp. Both almost 100% stock.

NX5 has to be one of the best chassis out there, you have to love the NF5 though for its NSR-ness. I'd be torn if I could only have one.

I'd want the NF5 because its rare and looks so classical Honda GP. The NX because of its tuneablity and available parts.
