Enough vs. Adequate?
In my experience, the N1K has plenty. My FJR had plenty. My VFR had plenty. My Magna had plenty. My SV650 has plenty. Even my on Seca 600 had plenty.
The only bike that I found myself occasionally wanting more was the SV650. Having upgraded the suspension, I'd find myself bouncing off the RPM limiter in the fast (100+ mph) sweepers. Track days I have to use the gearbox for all it's worth.
What seems more important is how these bikes make power, not how much, and how well it is mated to the gearbox.
The FJR had a mountain of midrange torque I could usually leave in 2nd or 3rd through the twisties. Like the N1K, passing cars doesn't really need a downshift either. So in this case, more power simply means less footwork. And a more relaxed touring RPM.
The N1K has a nice big pile of torque in the middle RPM's and less weight to haul around, but gears 3,4,5 are too close together to really be usefull and again the power is mainly used to avoid shifting and riding in higher gears.
Both the N1K and FJR had decent power above 7k but both engines vibrate enough there to feel unsettled. Not the VFR800 (gen 5 .. no vtec). The VFR's engine is the best engine I have ever ridden. It is down on power compared to the N1K, but it has smooth, linear and useable power at every single RPM. It never complains or feels like it is at an awkward RPM. In my opinion, it is also one of the best sounding (and feeling) motors made. I just can't do the riding position anymore, and I would so love to buy it back from my brother and fix the ergo's.
Power is an insidious thing. Each of my bikes had more power than the last, none were inadequate, but eventually I got used to it, and then appreciated more.
