I went from a pretty modified VTR1000, custom penske shock in the back, Revolution fork tune. Motor was putting out a dyno verified 108bhp to a VFR400R and what a difference.
The turn in on the NC30 is awesome, made my storm seem very slow even though the suspension was tweaked. Granted its down by over 50 bhp on the VTR, but still been able to show up the likes of Clio 182 sports from the lights, just keep the revs above 10k rpm and your laughing.
That bit suprised me about the 400, the engine is very tractable, not as good as the VTR, but then i used to able to go to work on the Firestorm and leave it in 4th gear for the whole journey.
Both bikes are good at what they do, NC30 for blasting round back lanes and upsetting bigger bikes with awesome corner speed, VTR good for being "typical honda" and so easy to ride, but with compromised suspension parts
Push the VTR hard and the suspension shows it's short comings, plus you can empty the tank on the VTR in under 90 miles!!
As a first bike, the NC30 is a brilliant idea, teach you a lot about riding and cornering.
Oh, and VTR speedo's are terrible at over-reading they can be over 15% out at the top end, which is good, since you wont be going as fast as it looks. Fit a sigma BC800 to cure this.
