There are exceptions..Rollie Free's HRD Vincent Black Shadow run at Bonneville Salt Flats Sept 13, 1948 150.313 mph

Oops just looked it up, his HRD was rated at 70 hp so guess you are right lol ..a stock Vincent was rated at 45 horsepower

If I ride a bicycle with high gear, my top speed is 40 MPH on flat road. I change gear to lower, my top speed is 15 MPH but I can climb hill at 6%, A very strong rider use the same bike, his top speed on flat still 40 MPH; on lower gear, his top speed is 25 at 6%.

so horse power is just one element of the real power. 65 horse with 105 lb of torques have much better top speed than 65 horse with 50 lbs torques

any engineer can shred light on this?
Not sure what you mean by "real power". HP is a measurement of power. Torque is a measurement of force. Power is derived by measuring how much force can be delivered over time. In other words, torque is one component of power.

Where top speeds are concerned, you want to know how much power is required to overcome the increasing aerodynamic drag as speeds increase. More power lets you overcome more drag and nets you a higher top speed.

I would suspect that a 65 hp motorcycle engine that produces 105 ft/lbs. of torque would have an unusually low redline. While it would probably give your neck a good snap off the starting line, it would redline long before it set any speed record.

A motorcycle that produced 50 ft./lbs. of torque and the same 65hp would likely spin a lot faster to make its power, be slower off the line, and reach the same top speed as the torquier bike (assuming both hypothetical bikes have the same drag profile).

Note: the above applies to top speed only. The relative importance of hp v. torque in other types of applications (i.e. drag races, road courses) is a lot more complex and application specific.

Top speed is basically power vs. drag. You can increase power or decrease drag to go faster.
Does the search work? I am mobile right now can someone please search Rev limiter and post a link to those results as there is at least one thread that talks about getting past this hangup, rev limiter/speed limiter, that has so many in an outage.

Then those in an outrage can mod their bike and then come back here and post how fast they pushed their cb to on a race track/drag strip.

Many motorcycles have been speed limited in the USA since 2001 and I doubt its printed in any of the sale brochures/promotional material put out by the manufacturers..the Suzuki Hyabusa, ZX 14 kawasaki, some Ducatis, the latest KTM, Aprilia V4, BMW 1000, MV Augusta, even the lowly Honda Fury if memory serves me, and there will be more to come.

The CB 1100 is speed limited because we were never supposed to get it, therefore is was limited to domestic regulations of 112 mph ( domestic being Japan). Americans begged for this bike..maybe we should have begged, but added the caveat " but only if it isn't speed limited", in which case we would have never seen it. Point is, we got the bike, the speed limiter in on there, so the solution as I see it is simple, either accept that fact and move on, or sell the dang thing and get something faster.

And do the homework ahead of time to ensure that the new faster bike does not have a limiter or any other forms of "big brother" on it. Better yet, build your own bike then you would know for sure it was free of limiters or restrictions...

You left out one solution. Figure out how to get around the speed limiter and make a small pile selling your solution to those who don't want it on their bike.

The 'busas and ZX-14s that have been limited to 186 mph since 2000 have workarounds available. It's been awhile since I looked into it, but as I recall, one of the parameters for the limiter was being in the top two gears. The solution was a gadget that fooled the ecu into thinking that the bike was in a lower gear. Bike thinks it's in 4th, so the limiter doesn't activate.

I have no idea if our CB1100 limiters are similar, but the bottom line is that the limiter is based on a computer running a program. If you learn enough about the programming, you can likely hack your way around it.
Yea...i'm not near smart enough, but if one person is smart enough to make something, someone else is smart enough to work around it.

Thing is, lets say you found a way to bypass it, chances are you'd gain between 13 to 23 mph on top end ( can't imagine this bike being good for more than 125-135 unrestricted) and relative to other offerings, you'd still have a very slow dog in a very fast pack.

BTW I went over to the UK CB 11 site which I am also a member of which is older ( but not as active) as this site, and typed "speed limiter" into the search engine, and either they are not aware, or they don't care, as there were no responses to the search.

Maybe because overseas has been living under big brother and have accepted it... Here we are just a rebellious bunch and it is just a preposterous thing to have a limiter on our bikes!

As far as tricking the computer, lets get some of those hackers in the third world countries that are trying to hack everything to develop a hack for this limiter issue! Maybe they could even program in a popup or something to trick the limiter...???

+1 on all of the above.

Gentlemen,

I started riding on the street when I was 14 years old. Over the last 43 years I have never been without a street legal motorcycle and I have spent countless thousands of hours riding both on road and off-road. During those thousands of hours I am equally certain that less than five minutes have been spent at speeds above 112 mph and I was as nervous as a cat on a hot tin roof during those brief periods of time. A trip to the drag strip would be about the only time that the speed limiter would be a hindrance as the top speed of this bike can be achieved in less than 1/4 of a mile.

As a drag strip weapon the CB1100 would be a dull blade with or without a speed limiter. In it's element however, the big CB is brilliant. Last night in the cool desert air north of Scottsdale, Arizona my CB1100 shot me from corner to corner in a most satisfying display of power and poise. It's Staintune exhaust note provided a fine soundtrack as well. Any enthusiast who can appreciate an air cooled Porsche 911 with all of its quirks and idiosyncrasies would have to love this bike as well.

When it comes to the type of performance that I find exciting and that always leaves me looking forward to the next ride, the CB1100 is peerless.

I think everyone in this thread agrees that this is a good bike, not a single person here is saying the bike isn't good, else they wouldn't be here.

What we are saying is the limiter is unnecessary and actually an EXTRA item they added on in order to LIMIT the bike's capabilities.

Now that I understand we were never 'supposed' to get this bike it makes it being imported into the US all okay. Because clearly we got the EXACT same bike as the japan market. I mean after all, that's why we're stuck with having to convert those pesky KM/H gauges to MPH in our heads on a daily basis Rolleyes

Full disclosure: I have not been to a track day, nor have I raced. I've thought about a track day to learn more about the handling limits of my bikes, but not really interested in all out speed. Seems like it would be a good experience and nice knowledge to have.
I have Guth, about 50 track sessions 40 at the intermediate level. What you learn on a track will make you a much better rider on the street. So, put on a full set of leathers or 1 piece and go for it Thumbs Up
