Honda then dressed it up in fancy clothes, gave it cheap and nasty USD forks and SM wheels and called it the FMX650, still with a lowly 37hp, and that's at the crank - expect a mere 30 at the rear wheel! (That'll be why it felt slow for a 650.)

I had an NX650, and it was a good bike in its day - but that was 1989! The FMX is 80s tech, detuned for the 21st century. They unsurprisingly never sold many of them (you can see why if you've ridden one) and the plug was pulled.
