Its getting close to getting new tires for my '09 CR and I was thinking of a 190/55ZR17 rear tire, inspired to do it because it is the size on the 1190RS. My main questions are these. Are there any fitment issues due to it being a taller tire? And For those who have the 190/55ZR17 how is the handling compared to the stock 180/55ZR17? I am sticking with the same brand and make of tire (Michelin Power Pure) and the stock 120/70ZR17 front tire. Thank you in advance! | ||

I run the OEM Pirellis. Corsa III since 2007. I have read here that Eslick ran 190s when he won it all. IIRC fitment depended on maker. Jdugger is the best brain here on this question. Z | ||

the ama runs 190's but then again the ama bikes run chain drive which has more clearance for the taller tire. there have been guys here that have run with the 190's on the street. completely different tires than what is used by the ama is what you'll get online or at your local bike shop. dunlops website has some of the N-tech tires for sale but i couldn't say for sure if they are the same tire or not and honestly either way they aren't street tires. rim width is a concern by the numbers but seems to work ok. basically i guess what i am saying is change the tire size at your own risk. there are many variables that no one has control over that could give you different results than me and so on. | ||

Wanting to do something to your bike because the racers do it to theirs doesn't make a whole lot of sense unless you're an aspiring racer too. For street riding, I am more than happy with a 180--I honestly couldn't expect a 190 to be an improvement in any way, and I'd be a lot more worried about it compromising my contact patch, and therefore grip, due to a 190 generally being designed to run on a 6" wheel instead of a 5.5". | ||

The 1190RS uses a different swingarm, chain, and wider wheel than the 1125, it was designed for the 190/55. | ||

different tire manufacturer's measurement for a 190 width tire varies between each company. usually pirelli and michelin's 190's are wider than dunlops but that can still differ based on model. if youre just changing the tire size for the looks, just remember that a 190/55 that will fit w/o rubbing is not really going to look much wider than a 180/55 that you there now. a 190/50 is going to look nice and wide but your handling is going to suffer, although that wont matter much if youre slow anyway. | ||

yes froggy it is. however i was ref to the 1125R dsb spec bike as that would be most applicable here. | ||

Lots of good observations and advice here. 190/55 is taller, and will put an already nervous bike on it's nose even more. If you go that route, you should experiment with raising the front, probably as much as the tubes flush with the triple as a starting point. It *will* fit, but just barely. Handling isn't ideal, IMHO, and certainly not without geometry changes. For street, the 180 is the way to go, IMHO. | ||

> I have read here that Eslick ran 190s when he won it all. Correct. The Dunlop 190 is also designed for a 5.5" wheel. Most other manufacturers intend the 190, especially a street tire, for a 6" wheel. In a Dunlop race tire, they sell a 200 for the 6" wheels. That's what EBR is running on their superbike, for example. | ||

I tried a 190 one on my 96 S1 (PM wheels) years ago. The turn in wasn't as good, it felt like a mostly worn 180. My GP Suspension'ed CR is fine the way it is on 120/180 Michelin power pure 2CT's. | ||

Are you using all the 180 on the street? Is it a Jersey thing? | ||
| Boogiman1981 |
Dugger they are running the spec 190 same as everyone else in AMA Superbike | ||
| Dannybuell |
pretty much most of both tires. Typically the fronts become pointier, all sidewall wear, the rear scuffed to about 1/2 inch from the edge. | ||

> Dugger they are running the spec 190 same as everyone else in AMA Superbike I'm almost 100% sure it's a 200, and I believe the teams have a choice of UK made or American made. I'd be happy to be proven wrong on that, though. Dunlop only recently released a 190 rear slick in the American made tires, to my knowledge. The UK tires are significantly better, IMHO. http://dunlopracing.com/tires-products/ | ||

Lol yeah I think I'll keep with a 180/55ZR17. But the 180 doesn't have that much more to give abd I figured that doing a 190/55 would give me that little bit more to even out the tread usage between the front and rear. I run the power pures now and love them but just wanted to see if there was anything else I could do to get a bit more out of Lizzy. | ||

When Higbee was running his STOCK 1125R at Willow a few years ago, depending on the construction SOME 190 Dunlops really rubbed the swingarm HARD at speed. TRASHED a tire in a 20 minute session. | ||

sorry it's a 195 or a 200 i could've sworn when i was getting the tires mounted for shawn in atl and sonoma they were 190's ah well memory isn't all it's cracked up to be... http://www.amaproracing.com/assets/2012-AMA-Pro-Du nlop-FAQ.pdf | ||

The 195s are UK made. Also have the GP moniker instead of the GPA. The GP tires are UK made and far superior to the US made GPA, IMHO. Supposedly the new GPA slicks are close to UK quality, but at the much cheaper GPA price. Testing here in Texas by some of our club's faster riders suggests the GPAs still have a ways to go. The GPA DOTs continue to just suck. They tear and collapse on our bumpy tracks here in Texas. But, man, that UK tire is really something... | ||

I tried a Pirelli diablo corsa whatever (their DOT 'race' tire) in 190/55 on the rear of my CR (and standard 120/70 in the front) last year. I put these on at a track day and thought they were great. The bike did seem to want to "hunt" a bit more in transition, but once set in a corner I felt like I had less side slip plus more drive at the exit. Bigger contact patch there, but the center tallness did make it waver a tad. I wouldn't wanna run these at speed on any fast track where there are rough transition without a damper. On the street, normal riding they're fine... but in canyons for "spirited" weekend rides they seemed to take longer to warm up if they ever got to full temp at all. So there I am with supposedly VERY sticky "racey" rubber on my bike and going slower than I did with sport-touring tires because the back end was fidgeting too much to inspire confidence. When I wore em out, I replaced em with michelin pilot pures and a 180 in the back. Very happy with this for my street riding. Got a second set of rims for track days. Separation of church and state seems like the best way to go... |
