Yeah but.... The Kawa 900RS only just came out. (I can't find one to get a test on!)
If you have a 2013/14 CB1100 that you've already paid off then throwing even $1000 dollars at it is better value than going out and buying a new bike off the showroom floor.
For that $1000 you could add a fair bit of oomph to the engine. Certainly enough to keep you excited about your 5 year old bike.
I also believe there are some people who like to keep their bikes a while, grow with them and build up miles on them. Just chopping in every year for the latest can feel a bit soulless, although there is nothing wrong with doing that if you fancy. It's just not everyones cup of tea.
The Kawa is also a liquid cooled engine, if you want to keep it air cooled then your looking at a CB or ...??? I'm struggling to think of many other big air cooled 4's. You could go twin, but that's different again.
I totally get throwing a bit of money into your bike to keep it feeling peppy and exciting. After you've had your bike a while you can get used to the speed, so it's a good feeling to find a few more horses.
In fact, you could pick up a used 2013/14 CB, throw $6k at it and get the same curb weight and HP, and more torque at the back wheel than the new z900RS - not to mention top shelf fully adjustable suspension, a smoking paint job and some body work bling. It would have plenty of power, great handling and be a totally unique, air cooled machine... you'd still have a bit of change over the new bike. It depends what makes you happy...

The man makes a point.
I have no issues with a person spending their money however they wish. For me personally I don't think spending big money for performance enhancements is a wise investment. I spend my farkling money on gas, tires and motel rooms...and maybe some safety gear when I find it on sale.

theoretically.. 4.8 HP & 3.18 torque more = :rofl: = sorry, but for me not worth digging (compared to baseline). How much did you spend on mods?
I'd like to see results BEFORE mods, for further assessment please.
:beerchug:
pb The benefit is in cleaning up throttle response, reducing driveline lash (fuel cut eliminated) and popping, more efficiency, and generally improving the rideability of the bike. A little bit more power but an improved power band can really help the feel of the bike.
That said, I never did get around to sending my ECU to Don Guhl because the 2013, mine anyway, ran very well.
I would not want to think I'd have to reflash a 2017 to cure any problems. I hope they've gotten that sorted out with the Euro 4 and so on.

Not likely to be any real discussion about power mods for this bike. Not much can be done with it, except possibly cams.
The Triumph Hi-Torque 900 is a good example, though.
A company determined that engine is extremely understressed and have developed a set of cams that will produce nearly the same power as the T120 engine.
Only problem is the chassis cannot handle that power, and the bike only weighs a very few pounds less than the T120/Thruxton.
So just buy the Thruxton and get a bike designed to handle and be safely ridden with that power level, rather than destroy or compromise the handling and reliability of your 900.
Same would go for the CB1100. For SURE hotter cams could crank up the HP, and the engine could probably stand another 15 HP without any problem. But then we still have the issue of the old-school chassis and suspension.
Notice Honda did NOTHING in terms of increasing power on the '17 model. Just refinements to the powerband, suspension, and handling.
The bike just does not need, and cannot benefit from, any more power.

I meant generally, not for CB...necessarily...now days with hi tech, real effect mods are just tooo expen$ive or impossible to do by single bike owner.....
Cams alone will not do too much either...total redesigning, backed by proper engineering is needed = moving into racing field or get factory involved.
And agree with you that if Honda did nothing, nothing we can do either...so aftermarket power increase gizmos are just a big fake but people without automotive knowledge are just hallucinated with their ads/product:-/ and keep buying them.
I wish them good luck and peace of mind after installments:worship:
I am happy with my CB's HP...IF:rofl: Honda gives me more = sure I'll take it ...lol

Also, while someone might not see too much difference on the dyno chart from adding a device like a power commander, I do believe that the changes that they feel when riding the bike are more significant. From that standpoint I can understand this mod in particular.

I spent a lot of $ customizing my '03 Harley, most of for either comfort, versatility or power - very little on just plain cosmetic changes.
It took me 10 years to get it the way I want it buying a few parts every winter and installing before spring. Counting the sidecar I estimate i have put an additional $25,000 into since I bought it new. But it was the only hobby I had outside of the Army so I don't regret a penny of it.
Of course now that it's perfect I can't ride it very long because of my back. Such is life.
War story (for Used2b) - when I was in Somalia in '92-93 we used to bet on scorpion fights. I had a champion I named Festus, he won all fights until someone threw a centipede into the "ring" with him. The centipede's whole head opened up into a giant mouth (think the movie Tremors) and promptly chomped off Festus' head. After that we killed all centipedes we saw. I still can't talk about the camel spiders.

From that standpoint I can understand this mod in particular. 89 HP vs. 86 HP (claimed), but with the weight gain, it's negated.
To be clear, the 2014 Deluxe is the heaviest model ever released at 571 lbs. wet. The Standard is 540 lbs., and the 2017 EX is 562 lbs.
The Standard has the best power/weight ratio but it's inconsequential.
When I said Honda did "nothing" I was really thinking figuratively, since a 3 HP gain offset by the weight is not going to add to the thrill of hard acceleration!:biker:

The new bikes actually make less tq, at a higher rpm than the old ones..
Of course this is all from script from publications.
The real way to know would be to have 2 stock bikes, one old, one new, on the same day, same shop- dyno them.
The motor is 100% the same. All that changed is the intake boot on the airbox (part that people remove for the TSR plate) and the ECU tuning.
Cams are where the power is hiding in this engine.
Every other mod is fluff in the real world- meaning yes a muffler, decat, or tune might get you couple more hp but not enough to win the race against a rider who is only slightly better or even slightly lighter - if even just a drag race.
A few hp gain can easily be 'lost' depending on where your shift points are, rider weight, a moments hesitation, etc..and that is not even taking into account the 'launch' if at a dragstrip or red light.
To truly have a bike that can beat the other bikes consistently and somewhat easily- cams are what needs to be done...as well as more aggressive gearing.
All that being said- and I am an engine hot rodder at heart (none of my stuff ever stays stock)... on this bike it is all just for fun.
Could someone be the hottest CB1100 ever? Sure- and then get passed by some kid on a stock (just about anything else)...who isn't even trying.
That being said- I still do enjoy seeing what I can get out of things.

Before Yamaha utilized reed valves on the intake (1972?), a fair amount of HP was easily gained by skirting the intake side of the piston by ~1/4 inch and by replacing a stock exhaust with an expansion chamber.
Thanks for the walk down memory lane.

Even after reed valves, opening the intake ports in the pistons and trimming the piston skirt, stuffing the holes in the crank and milling the cylinder head was still the hot ticket for going fast on a Yamaha mx bike.
Two strokes were so easy and cheap to hop up.

The new bikes actually make less tq, at a higher rpm than the old ones.. I pulled those numbers from a couple of tests; pretty sure that my '13 did say 86 HP somewhere. Those are Euro numbers on that spec page linked above. They can be quite different. Euro ZX-10R makes 15 HP more than the US model! Reflash cures that but I don't miss it, so I never flashed mine.
Difference is very minor but it's all in the cams and ignition timing, compression ratio, etcetera.
A guy COULD make a real screamer out of a CB1100 no problem, especially the RS. 105-110 HP is very possible. The chassis could handle it.
It would sure make it a very lively competitor to the Z900RS although still much, much heavier.
Those centipedes are real dangerous. Almost as dangerous as the amount of dough you can pour into a motorcycle!Banned_imp said:
Calls to mind "House of Pride" by Jack London:
"And I must tell of one other thing. It was down in Kona, -- or up, rather, for the Kona people scorn to live at less than a thousand feet elevation. We were all on the lanai of Doctor Goodhue's bungalow. I was talking with Dottie Fairchild when it happened. A big centipede -- it was seven inches, for we measured it afterward -- fell from the rafters overhead squarely into her coiffure. I confess, the hideousness of it paralyzed me. I couldn't move. My mind refused to work. There, within two feet of me, the ugly venomous devil was writhing in her hair. It threatened at any moment to fall down upon her exposed shoulders -- we had just come out from dinner.
"What is it?" she asked, starting to raise her hand to her head.
"Don't!" I cried. "Don't!"
"But what is it?" she insisted, growing frightened by the fright she read in my eyes and on my stammering lips.
My exclamation attracted Kersdale's attention. He glanced our way carelessly, but in that glance took in everything. He came over to us, but without haste.
"Please don't move, Dottie," he said quietly.
He never hesitated, nor did he hurry and make a bungle of it.
"Allow me," he said.
And with one hand he caught her scarf and drew it tightly around her shoulders so that the centipede could not fall inside her bodice. With the other hand -- the right -- he reached into her hair, caught the repulsive abomination as near as he was able by the nape of the neck, and held it tightly between thumb and forefinger as he withdrew it from her hair. It was as horrible and heroic a sight as man could wish to see. It made my flesh crawl. The centipede, seven inches of squirming legs, writhed and twisted and dashed itself about his hand, the body twining around the fingers and the legs digging into the skin and scratching as the beast endeavored to free itself. It bit him twice -- I saw it -- though he assured the ladies that he was not harmed as he dropped it upon the walk and stamped it into the gravel. But I saw him in the surgery five minutes afterward, with Doctor Goodhue scarifying the wounds and injecting permanganate of potash. The next morning Kersdale's arm was as big as a barrel, and it was three weeks before the swelling went down."
