CB1100 is under powered

[cbdtran_imp]

I have the bike for 10 months, and always feel the bike is under powered. One up is okay, but 2 up I can feel the bike is under powered in city traffic. On long country stretch, to pass a car at 75 MPH it is not always as easy as i think it should be, it have to be quicker in a limited time frame, the bike requires more time and distance and timing to do so at 4th gear.

this bike is a casual ride for its cc volume, well behaved and yet needs some more torque. How about 105+ HP and 80 lbs/ft w/o sacrisfying MPH? Do I wish too much?

The bike wasn't spec'd for that.
My old long gone air-cooled FJ1100 was far more sprightly than the CB1100 and is probably close to or a bit beyond what you're looking for. Meaning that it is possible to get an air cooled 4 cyl 1100 to do what you ask, it's just not what the CB1100 is.
Even so, to make a quick pass at freeway speed on the FJ1100 still required 2 or 3 downshifts to get into the power band.

I've never tried a ZX-14, maybe that was what you're looking for (?)

I can see how you would feel that way riding two up. There are a number of people experimenting with getting more torque and hp out of this bike. Do some searching for the ecu/ecm reflash. If you do a lot of two up riding, you may want to look at another bike.

Try a Suzuki Bandit 1250S...

I only ever ride alone, and with my 195 pound weight, the bike has plenty of performance for me.
But I also can see why you would feel that way with two on board. The added weight would certainly test the CB's modest power and torque and you probably made the wrong choice for two-up riding.

Yep, always wished this bike had 135 HP and weighed 40 lbs less...but does OK for my new slower style and keeps me out of trouble.

I was cruising around at 260# all by myself and I never really thought of it as under powered, but then again I came from a 750 nighthawk soo....

I even did some 2 up riding with a close to 200# passenger and it did feel a bit sluggish at that point, but hauling around 300# shouldn't be an issue I wouldn't think.

Just clutch, click, click and go.

Accelerating in overdrive gears is a bit counterproductive isn't it? I think the CB does a great job pulling in 5th and I'm roughly the size of a polar bear (whiter, though).

I did have my ECM reflashed but even before that my bike still ran great just runs better now. But when it was bone stock mine would run 100 plus in 2nd gear I think! I have another bone stock bike I will try it maybe it's over 100 in 3rd gear even hit the speed limiter. I think some of y'all are scared to rap up the rpms!! It don't start pulling till your over 7k and let they baby hit 9k then shift again. You want need 4th gear

this bike is to pay homage to there cb line of bikes of the 70's not to make huge hp & torque #, you bought the wrong bike.

In a Honda video, the designers said that their goal was to make riding the CB "like taking a walk in the park.". I'm sure they could have gotten more power out of the engine, but they said they traded that for an incredibly flat torque line and smooth throttle response.

Having said that, I'm sure 100 HP is a very attainable number for this engine with the right mods. Intake, exhaust, a fuel controller, and a dyno tune should get it pretty close.
