Just got through installing a new Pirelli Diablo Supercorsa in 190/55 on my Ss. Nice round profile, higher profile may drop the revs a bit while at highway speeds:  Tons of clearance on the swingarm and belt. Hugger probably won't fit but I haven't had it on since the day I bought her:  Just eyeballing it, the tire doesn't seem to stick out past the rim much.  My CR with stock tire for comparison:  Please spare me the 'incorrect size/handling suffers... blah-blah-blah' ad nauseum. Wheel removal is just like everyone says, only really need to do the pinchbolt and axle. I went ahead and removed the caliper too since it was only 2 bolts and I didn't want the caliper to mar the wheel due to my clumsiness when I jockeyed her out. YMMV, Nels | ||

You might try raising the front (dropping the forks in the triples) to compensate for almost a 3/8 rise in rear ride height. That will definitely tend to make the front a bit squirrely on turn-in and especially in braking. 190-55 is a good choice (it's all I use) - but see IF you can level the bike better by raising the front to match (wish ride height was adjustable on the stock shocks) Oh - and your tires should clear the hugger just fine - even at a "couple MPH" over the speed limit. | ||

Looks nice. I just put a 190/55 Battlax bt016 on the rear of my XB12S. my hugger and belt guards fit fine too, but I have the upper belt guard removed for looks. Handling is great too.  | ||

What made you guys all choose a 190/55 over a 190/50? Did you specifically desire the additional height for some reason? Did you get a good deal on that size? Something else? I'm actually very curious on this! I have often gone to a 190 on my sportbikes...but always a 50 series tire... | ||

Slaughter - Great info, thanks for the heads-up! Will definitely look into ride height. Atomic - Belt guards? What are these belt guards you speak of?  Andymnelson - Pirelli Diablo Supercorsa is only available in 180/55 and 190/55. I wanted to go bigger so choice was easy. YMMV, Nels | ||

Andymnelson: I got a great deal on these tires on Craigslist and couldn't pass them up. Forerunner: Looks like you have a helmet lock installed where your upper belt guard was. (nice) | ||

As Steve said you can raise your forks. But you can also run a 190/50 instead and not have to do that. | ||

Atomic, Damn you've got a good eye! Yes, I bought a Uly helmet lock and with some barstock aluminum I had onhand made a simple mounting bracket. The Uly lock is threaded (M6 or M8 x 1, can't remember) so a couple of allenhead bolts from the hardware store, a few bucks to the local locksmith to have it keyed to my ignition key and good to go. I just found R&R'ing the seat and futzing with the cable every time to be a PITA. One caveat, I always have a bandana with me to put between the helmet and swingarm so they don't scratch each other.

I use the 190/55 on the racebike. Good pricing from Pirelli - but it did require some suspension adjustments. Penske rear shock is ride-height adjustable but I still raised the front too. Just took a little homework to get her dialled in. Like the way it handles better now that it's all set up. As a side note, I don't really think it looks all that much bigger than the 180 | ||

Okay so my question to you guys is what is the approximate difference in rear ride height gained on a 190/55 versus a 190/50? I realize this will vary a bit by tire brand/model, but just curious because I wouldn’t mind a hair more ground clearance for my turbo (yeah I realize I could adjust the rear suspension too). | ||

Using the Pirelli Corsa III data as an example. 180/55 a diameter of 645mm 190/50 a diameter of 640mm 190/55 a diameter of 650mm Your tires may be different, but in the case of the Corsa III the 190/50 is actually a bit shorter than the standard 180/55....but the 190's were measured on a 6" rim, while the 180 was measured on a 5.5" wheel...so the actual difference may be less.....and BTW Pirelli lists a 5.5 wheel as acceptable for the 190 size tire... | ||

Well Based on Fast's numbers The 180/55 is 25.39 in in height The 190/55 is 25.59 in in height so since half that height is above the axle your talking a tenth of a inch in height gain, look at your ruler, hmm eighth of an inch is bigger, but still awfull small. did the mm to inch conversion here http://mdmetric.com/tech/cvtcht.htm not sure if doing it for height really would be worth it ymmv | ||

but still awfull small. Everything to do with suspension is pretty small. Small does not mean "little difference" | ||

Are those diameters on the 5.5 inch rim and inflated? Those diameters look more like on their "proper" rim. Squeeze a 190 down to mount on your 5.5 inch wheel (1125, XB) and it gets "taller" - I'm betting by almost 3/8 inch. If I recall, the "stock" width on typical 190 wheel is 6 or so inches. I could be way off on this, never measured. Just took the Pirelli guys recommendations - http://www.ctracetires.com and tuned suspension to suit my own weird preferences. Works well for me. Your Mileage May Vary. | ||

Atomic...your bike and mine are identical twins...well they will be after this week...I will be getting a new center tail piece and doing the turn signal delete...now all I will need is a tire to match...I'm gonna try a 190/50 Corsa III while I can still get one.. | ||

I know it doesnt take much as far as suspension adjustment, I was just pointing out the minor difference if one was to do it for more ground clearance. On a similar note, a couple of Uly guys have put on the 190/55 Scorpion Trails, and so far havent seen any complaints as to weird handling. Ymmv | ||

Oh yeah contrary to how my previous post sounded I certainly wouldn't be doing it just for a height gain, just more curious what the actual gain in height would be. In reality I don't really want to increase my ride height, but like I said before its a trade off since at the same time additional turbo clearance would also be nice, but overall I'll just stick with being careful around speed bumps. My turbo clearance is about the same as the stock muffler. Otherwise I do like the look of the 190, even if it is just a slight difference. | ||

Show-off. j/k Looks awesome. Is that the Dunlop? Nels | ||
| Im_joedirt |
lol I think so. unfortunately it has Harley Davidson printed on the wall. I think it was off a rocker c. Wasnt showing off just showing that i think thats as big as you can go with out mods. | ||

Slaughter, How do you like the 190 on the track? I've been debating on trying it, but was concerned about squeezing it onto the 5.5 rim. The other aspect is the increased rotating mass, will rob power, and so far the 180's I've been running have been sticking pretty good. Back in my R1 and GSXR days, when we switched to using the Dunlop 195's we lost 5+ hp on the dyno....but the traction was worth it. In this case I don't know. | ||
| Slaughter |
I swear by the 190. I did drop the rear and raise the front slightly after a couple days sorting the handling. It SEEMS to work just a little better for me in the power-on exits. Not really a scientific statement because my "improvements" were also after being off the bike for a year after wadding it up. Now that the handling is sorted out, I'm staying with them. I only run slicks. This is the california desert, the only water we see is in our ice chests. (well, OK.. once every couple years, it'll rain and then lightly enough that we just throw on DOTs and I hand-cut the tread out to the edges) | ||

well I may have to try them, thanks for the info. | ||
