Michelin Tires
I have read many times that a 190-55-17 turns better than 190-50-17. Never realized
the Big difference. Mike just installed a set of Pilot Power 2CT the 190-55-17 rear
and I have a pair of Pilot Road 2CT 190-50-17. We traded 14's........... the 190-55 turns Much Quicker.
Old news to some of you that ride in the curves, cool really feeling the difference. Just ordered a pair. sportbiketrackgear.com $247.00 TMD. for the pair. Scuff them in and go to
Arkansas in 2 weeks. Ozark Mountains for 3 days if any of the DFW members want to go.

So why is that ? I have had two 14's so far but i don't know the answer to that. I have put new
springs on both, which makes a big differance as well, but don't know jack about the tires...
Also, will that throw the odometer off at all????

That is very cool Louis!
I've been using the 190-55 profile for years now and I will not go back to the stock size ever again.
The handling improvements are well worth it

It is a road race profile tire and the extra height helps the bike turn.
It won't throw the odo off but the speedo will read a bit slower .

I was Shocked at the Difference, only had this 14 for 18 months, went from the stock
tires to new PR 2CT and that was a stepup. Don't do burn out's......yet.
So for now the 190-55 . Down side is my PR2CT last 7,000 miles.

Thanks for the heads-up, LAB3 
In looking at Michelin's site it recommends the Power Pure tires, for the ZX-14. Listed at 85/15 street/track use, they say "Superb wet and dry grip, handling, cornering stability and feedback". And they are also available in a 190/55ZR17 .
Does anyone have experience with these? I assume the only downside (but hopefully not 'lowside', or 'highside' -grin-) is that they'll wear more quickly?

I was told better grip, softer compound. Less milage. I am sure someone will chime in with personal experience. Do check out where I purchased the Pilot Power 2CT. No spam
here just a Great price.not old stock either.

I was trying to wrap my head around this back in the early 2000s when I had the 180/50 on my Yamaha and had some rear slide in the deep corners -- was told by another racer at the track to keep the same front but use the 180/55 rear to eliminate the problem, and it works. He said then that the 55 is a bit rounder profile and helps keep the rear off the bead when you're leaning hard for a little more stability. I never questioned otherwise and have ran the 55's ever since -- no matter 180 or 190, Yamaha or ZX14........and I was told the very same thing from the guy I bought my 14 from, which he had already fitted with the 55's and taken it out for some track days. Seems to be a hot tip with weekend twisty track lovers -- I'm a believer!

Wouldn't the odo be affected if the speedo is affected? They don't run from seperate sensors do they? I don't understand how this could be........I thought they shared a sensor and the ecu is programmed to calculate mileage faster or slower pending what speed?

Yes.... odometer and speedometer will be off..a little..... I will adjust the speedo-healer for taller tire. Think about a really larger rear sprocket .the speedo will be reading Much faster than you are really going and the odomter will show more miles than you Really traveled.

Isn't that the exact opposite?
The smaller tire will spin faster and the bigger tire turns slower?

Yes sir, that's physics at work -- smaller gyros spin faster than bigger gyros

simple geometry is all this is....you'll get the same effect if you pull the forks up in the triples 5-10mm. Only downside is that you are losing a bit of ground clearance. Not a big deal if are a flyweight.

Actually the taller 190-55 tire actually puts the factory speedometer closer to actual speeds then the stock tire, there is no speedo healer needed. My only gripe with Michelin's ive used is they don't give a early warning on adhesion limits, they just let go without much warning. It startled me a few times, i prefer Brigestone as you can predict when they are on its limits better through feedback and controllable slides.

Heal Tech has a calculator and it has a different set of #s for a 55 tire from a 50 tire???
I was told the the 55 taller tire would slow the speedo a little. Just the opposite of a larger rear sprocket.
I got the speedo healer when I changed to a 43 rear sprocket. Speedo was reading fast.

Yes but the factory speedo is off by 5-8% faster then its really going, so when you slap on a 190 55 tire it brings it closer to actual speeds since its bringing it back a little.

Did not realize my speedo was off when it was stock gearing and tires.
But I have gone up 2 teeth on rear sprocket and needed it then. For Sure :-)

Yes from the factory reads optimistic.
Installing a 190/55-17 will make it read closer to the actual speeds.
The ODO is still just about right give or take ... Probably take cause you don't get more miles on the ODO.

its no secret 55 tires turn in quicker. if your suspension is set, you'll need to adjust it for this tire.
also less contact patch in the straights, this tire will wear out quicker in the center if you're all about the freeways
bottom line is the 55 is a better performing tire profile.

Yes they go quick in the straights!
You gotta learn how to save the tire if you're gonna use it for a daily rider .
The most I've gone was 10,000 miles on a supercorsas. I broke it up between twisties and coast hwy runs from LA to Frisco . The whole rear tire from edge to edge was bald lol! 
The front was almost bald .
The fastest to being bald was 1500 miles.
5000 is about normal for me give or take.
They are expensive tires so I pick my times that I'll pull the trigger.
Unless I get a stock of take-offs then I'll let her loose at will

Louis have you done any roll-ons since going to the 55 series? How much did it hurt you in that way? Do you now need a 44 tooth to make up the difference?
