Sold an FZ 1 which made 124 hp, but was rarely able to use all of it, to buy the CB.
In the rev range I ride ( below 6000 rpms) the CB may make more HP and torque than the FZ did and probably more than the FZ 8 does.
Heres an interesting speed question:
Would you rather shift at redline
Where the bike makes peak horsepower
Or where the bike makes peak torque?
Depends on what you want to accomplish. If you're at the dragstrip, you're going to want to be shifting when the the hp has peaked. On most bikes this is pretty close to redline, but according to the dyno charts I've seen, the CB peaks at around 7200.
The CB delivers about 90% of peak torque starting at around 2800 rpm and peaks shortly thereafter. I wouldn't want to be lugging the engine by shifting that low all of the time. Since the the torque curve stays relatvely flat from the 3000 rpm range and up, it really doesn't matter if you shift at the peak or sometime after that. The torque delivered will be about the same.
I think Honda did an excellent job tuning this engine. They knew that the target market was not going to buy based on hp numbers, so they traded off hp for usable power throughout the rpm range. The result is a very well balanced engine with a flat torque curve and the most linear power band I can recall seeing on a dyno chart.

I just wring out every gear and let that nice limiter do the thinking for me!!

Listed at $500. Wonder if it brings anything new to the table.

What is there to be said from an engineering perspective of the CB1100 engine not being designed for top speed? Camshafts. Valves. I blew up a Chevy Chevette once. Snapped a con rod. It could not handle those rpms.

They should enable all bikes to pull to redline in top gear!
The CB11 was robbed!!
But the low end is much more important...

Was a Speed Triple pulling u?

Not necessary. With the proper profile, the CB11 could probably reach that speed if dropped from about 5,000 ft.

Lol! Here in south Louisiana the only way to acheive 5k ft. is by aviation...

Ah, the promise of optimistic speedos - the only way a stock CB1100 will do 130 mph is down a mine shaft with a tail wind!

Vehicle speed and engine speed are two totally different things. Also, though it doesn't look modern, this Honda was built with modern technology. Very modern.
Rev limiter is set by the factory and 8000RPM (or any RPM) in 1st gear is the same as in 5th gear. The transmission and everything else sees the difference. Engine does not. The time you spend at these speed may reduce longevity, but I severely doubt this. Again, modern engine, modern design; high load for 30sec-1min at near rev limiter with ample air flow won't mean a thing.

What do you mean at any or RPM in 1st and 5th????

Rev limiter is not the same as the speed limiter. They may function similarly, but they are not the same.

Sorry, I was trying to make the point that speed doesn't affect engine stress dramatically. If you're doing 8000RPM (or any RPM) the engine has no idea what gear you're in (whether it be 1st, 2nd, 4th, whatever). So it's not like doing 8000RPM under full load in 1st is different than 5th. So if you maintain the factory rev limiter, go as fast as you want. Rev limiter will prevent snapped/broken anything as a result to the engine speed being too high.

Oh that makes sense. Yeah I get freaked out going over 90mph which my bike does easily. Don't ever see myself going over 100moh so the speed cap doesn't bother me. My last bike I was all about modding the top speed, horsepower ect. but this bike is more of "a keeper" I want it to last and not planning on taking it to a track
