Hello.

Have you had a rear tire sized different than the original (190/50) on your ZX-14R ?

I would like to know if traction control would work the same, despite the rear tire size being 190/55 or even 200/55.

Thank you.

Hi there alfcruz, I don't think a tire size change will have any effect. You're talking about very small differences. I'm sure someone who actually HAS traction control will chime in. ( Mine is my right wrist!)
And, Welcome to the forum!

Oh, thanks Mad! Good to be here.

I have read many topics on wider tires, but nobody mentioned electronic abnormalities (with abs / tc). So I suppose you can, in fact, put a wider tire. Just trying to be shure.

I also have a Gen1 so was not able to comment about how tire size might affect TC. Better findout before you spend the extra on a larger size. "m guessing any size tire that fits the rim will be ok. I have not heard of anyone having problems with TC reacting to a 190/55 or a 200 yet and it probably would have come up if it was an issue. The stock size tire will probably lose about 10mm of diameter by the time it is worn out. A 55 is about 10mm higher than stock. I would bet it doesn't matter.

Hasn't anyone run a 190/55 on a Gen2 yet? I'm sure a lot of people must have.

Those are good words of advice, Rook. Thank you. Have read many of your posts regarding tires. Let's see if someone with a Gen2 bothers to tell his experiences with larger tire sizes. Thanks. Antonio.

Let's walk this thru...
I have a tone wheel and I think my factory set ratio of 50, now rolls a 55; will be intrusive to the k/skid.
I had an epiphany as if to think DTT. My tone windows will recognize a range of movement, intervene within a millisecond, never ending monitoring in DTT, is to trigger that threshold at the 55 ratio, take the averages it runs thru [you hope] and learns holding those rpm to mph to tone wheel sweep numbers, [you wish], because I have no clue.

However, home he here does not need the aspect so as far as to answer the question; will my 50 to 55 change> deactivate in any way; is no. Will this cancel out say if I were to spin the wheel or loft into a wheelie, would the intervention cease to operate is no way could it in the handcuffing [all systems working] off the DTT.

I will huff = Threshold
I will puff = Trigger
An blow your RAM away = Discharge

Every milli cut [slice a second down] to a milli is the monitoring time-span between mills is the discharge think; is that time span before the next mill comes up to grab a capacitor filling is E can be measured. Run any tire [aspect] you want [away] from stock, feel the twitch at the 3 points is ignore it, and/or take it as it's fully functioning you hit that threshold.

Know how your computer bike works so it makes sense you speak tonewheeltabling a tire change.

Make sense yet?

It will not affect your TC. You have a tone ring on both wheels. TC is looking for back wheel going much faster than the front before interviewing. Using a slightly taller profile tire is not going to make that much of a difference.

Wasn't there a momentary hesitation or a ping, when the tone wheels appeared and someone changed aspect ratios? That's what I recall. I can see that wheel spin up to a point and intervene. That was the complaint and all that was changed was the tire to a 55. I could be wrong and it was not it?

I don't recall anyone saying that after changing to a taller tire. Nobody has had a missing problem after raising their final drive ratio which is what's being done with avtaller tire. All sorts of people have missing issues after lowering the gearing slightly.

Sprocket change. Seen your moment and raise you one.

Hello everyone, thanks for the feedback. Do you, in fact, experienced those 55 tire profiles on your bikes, correct? I hate wasting money.

Yesterday, reading the Ninja manual, there is this quote. "The use of non-recommended tires can cause malfunction of KTRC. Therefore, always use the recommended tires for this motorcycle."

Now, just what is a recommended tire? My manual just mentions 120/70 & 190/50. I will try to contact the factory customer service to learn more about it.

Grateful, gentlemen.

And Hub... love your Buckminster-derived-organic-techno-math-writing-style. Thank you.

And alf... That's how to read the owner's manual is page by Page 82 and I'll paraphrase in the 'organic'...

'Change me tires, change a sprocket is not in a learn process, boo-who ever swapshit out against our formula we measured down to the last circle, the parts inside we are handcuffed to, you hit the brakes, T&T will calc out too much "table-phase" [call it] and make you stop on a dime is now the rear bumper.' 'Also, wit the fiddlefucKing, [as in Do Not Mess Withe BossPreSet], where anal logging a long one up in the air is more about to stand the bike up, not hover a few inches and drop the ign curve is you are on your own feeling the twitch to rpm to gear to flip over or flop the bike past the limit line is hello intersection!'

Why, it's write there in [read between the lines] print!

WATT is my mantra? Don't mess with a preset? Know how the strokes work is the same shit in this black box? Formula is King? Bone stock is me? Take your pick.

Wow. Shure I'd like to have in hands a copy of the english version manual, just to check that. Imagination rules, and perhaps even creates the holo-Verse. Thanks.

In the mean time, think I will, as a left-zero-track-day newbie, wait till Pirelli sends some standard measure tires my way.

Page 81 starts explaining how... "The computers integrated in the ABS compare vehicle speed with wheel speed.''Since non-recommended tires can affect wheel speed, they may confuse the computers, which can extend braking distance."

Formula so locked in right down to the aspect ratio, they even knew it would turn the tables to dump a lot of junk ratio-data at a certain speed. Yes, it will still compute. Yes, the result is more feet needing to stop knowing this.

Track junky, you can run 1 of 3 options:
1. Stay stock so no intervention if the systems are your safety net sort of speak.
2. Run the 55, feel the twitch out of the corners, you want it, you got it.
3. Pull the ABS harness off the control unit, pull the tone wheel sensor plugs apart; everything is back to full human control. Blue tape over the dash so the blinking doesn't move your eyes there and that lets you keep an eye on the tach instead.

My option is the first one. I am not skilled enough to run without the aids, or at least the fantasy of being protected by them. But I am inclined to give the 55 a try. Need to be sure that the bike will run with the controls swithed on as opposed to have to turn them both off. Or worse, that the bike will not misbehave grossly under acceleration or under breaking with the 55.

Surely somebody has already run one of them, 200 or 190/55.

You're really over thinking this. TC is looking for the rear speed sensor turning faster than front before intervening. A 1/2"taller tire isn't going to do that. ABS is looking at those sensors to see if they are coming to a stop when they shouldn't be. Again, your 1/2"taller tire isn't going to affect that.

Do a web search, there are threads with 55 series tires on there. Lots of hsppy customers liking the quicker handling. No reports of tc/abs problems I could find.

Much of what goes into owner's manuals is lawyer driven BS.

Put the tires on you want and go drive the thing.

I do, but then I am just a crazy old man, trying to touch the knees on the ground. Tired to see 250 Ninjas walking by.

Thought I'd present my two beautiful daughters to you, as them came to the world.

I think you'll like the Supercorsas for the track and I there nice for the street too. I think they do fine without tire warmers. You might not have a problem with the smaller bikes in the corners but you'll definitely blast by blast them without hardly trying on the straightaway (and they will hate that). You can drop the tire pressure. The tires will heat up fast and the air will expand. You might try as low as 28 psi front and back. That seemed to work well for me even though it feels squishy on the street. I did scrape the exhaust. Never touched a knee. If it's a hot day, you'll probably have no chicken strips after your second run.

"You're really over thinking this."

The factory is, right?

If I wrote machine BASIC? "Programming languages are sets of rules and commands that you, as the programmer, can use to express your program so that the processor can follow and execute it. Like any other language, a programming language has a vocabulary and rules of use."

So if I say in machine speak, the basics are: 'Let A = 50' is BASIC language. I did not program in 55 as a ratio, but had to write 50 so the TC/ABS operates in this parameter vs the next tone wheel and it's processor is going to use another written in aspect ratio is just saying there is a language the processor has to compute to binary code so it can process the chip you used. Then the next chip and that language used for those DTT numbers to dump.

That says also, for each 360 and no matter the speed, there is a math box that says, 'you are here, did you match 50, yes or no? Then this brings in the AND and NOR gates to say yes or no is the path to no if a 55 shows up. So the system is fucked no matter the speed. It just bucks or pings with that sprocket tooth speeding up/slowing down is not pinging in the spec the programmer used for that tone wheel operation he had to program, that sprocket number too.

See it yet? It wasn't a lawyer, it was a processing step and a caution saying... GATES of YES and NO. And they more or less said, use a 55 and the NOR gate will say, nor will I use this number is NO. And then the warning of hey, we programmed the processor to these numbers we measured in a circle is your ass is on your own you don't see the processing trying to find squids changing ratios on the net? No, read it right here, the clue was [for me] so fucking huge.

You still no get?

I'm running 190/55 Pirelli angel GT's and everything works as it did with the factory size.

confirmation!!

Rook? I just explained the why and you are seeing conformation is not in action.... YET!

From the horse is mouth is one up on use is and it's not my bike so book be damned...

Hub there are several members on this site running a 55 profile with no change in TC function. I'm not sure of your angle here. In the real world it works.../end of thread.
