I know the d675 came stock with the pirellis 180s for the rear tire, all of my friends run gixxers and they have changed their rear tires from a 180 to a 190 and they said it works better for them. I was wondering if any of you guys have done this to a daytona because I know the symmetry is different so the it could have a different effect. Did you guys like it? pros vs cons? would you recommend getting a 190? this will be a track only bike. I tried to do a search on this forum but I couldn't find anything.

It generally gives you a little more edge to lean on but it also changes the profile of the tire. I suppose its more personal preferance. I've been running a 180 rear but will try running a 190 rear this year.
thats what im trying to decide if I should stick with the 180 or go to 190, mainly because im trying to get a set of tire warmers and I would like to know what size to get
Im not sure.... I guess it depends on the manufacturer. this is the chart for DMP tire warmers
- Kit A: Front 110/120 Rear 170/180
- Kit B: Front 110/120 Rear 190/195
I run Dunlop gp-a's. They only come in a 190 rear. I like it. I didn't notice any loss in lower from the extra weight.
I think it all depends on the tires your getting. If its a track bike. Try it and see if you like it. If you don't switch back. Sell them on the forum. If you read on dunlops website they recommend their 190 for the size rim we have. Idk about other manufacturers but that most important. Are you cramming a 190 meant for a 6inch rim like a busa... (messes up the profile) Or is it made to fit your 5.5.
and most tire warmers do up to a 190. My moto-d warmers fit great with room for more.

What BMAF said is important. The Dunlops are designed for a 5.5", the others aren't. I hated the 190's (Pirelli and Metzeler) on my bike. The Dunlops were much better due to the extreme profile, but still not as responsive as the 180's.
agree 100%. To build further on that point, our bikes are very reactive. This sort of combats it added some stability. Now change the front end geometry and you have got yourself one hell of a bike.
a motorcycle is nothing but a variable. Nothing is constant. Everything gives and take. Add a 190: its raises the rear thus taking a tiny bit of rake and trail away. Combat that by adjusting the front end. I'm not saying you'll have to do that. I'm just making a point.
I would check with the manufacturers recommended rim size for the particular tire you want. If its larger than 5.5 IMHO its not worth it. You'll lose too much. It adds weight, distorts the profile and costs more. All no no's for a track bike.
However, I do love my gpa's and they love my bike. I rode Bridgestones for a while. The bike hated them. Made suspension felt wooden. I lowered the pressures below recommended values just to get some feeling. Which happen to make the tires act funny mid corner. I got a set of the dunlops cheap. It was like day and night.
plus that big ass tire looks badass.

With the warmers just get the bigger ones, you can always use a step down with them. Who knows later on if you decided to get a bike with a 190 or more.
Ive run a 190 on my street for a while as I was after slightly better tip in, have found tires can differ as well from oval shape to more round . the 190 super corsa I felt an instant change in how the bike handle mainly cause it was a taller tire it just tipped in so nice, im now running dunlop sport smarts which dont have the same tall profile so the initial tip in isnt as much as before.
and as a little side note the bike does look a lot cooler with a bigger tire back when you look at other 675's

When Paul Young tested the 190 rear he said it didn't suit the bike and he was slower with it on. That was a Pirelli 190 rear. I've always stuck with the 180s with me running the Pirellis or Metz but this year I have a set on Dunlop D212 GP Pros to try in a 190. Not tried em yet but the first thing I have noticed is how much taller the front is. The tyre is still a 70 profile but rubs on the mudguard (fender) and thats before its hot and expanded at speed. So I've had to ditch the front mudguard for testing in two weeks time in Spain. I'll report on the tyres when I get back.
Anyone got a quick fix for the mudguard?

Dunlop claims no expansion. I don't have any issues of rubbing when they are up to temp. It IS a squeeze with warmers. lol
Mudguard fix: You can get new bolts with finishing washers. You'll have some play like 3 or 4 mm... not to much but some. You could also try to ream the holes a little on the bottom. my .02
With the taller rear tire raises the tail, reducing your rake and trail. That's why it seemed to "turn in" faster. Not necessarily a good thing.
Less rake and trail = less contract patch = less feeling = crash!

Everywhere I go I read good reviews about Dunlops I should probably give then a try

I have tried lifting the mudguard on different bolts etc and removing the guards. Still no joy. I've made a new mudguard up and drilled the holes as low as possible and it just clears but when you get any rubber or grit on the tyre as you come back into the paddock it rubs like buggery on the mudguard. I'm now making a completly new one which will be flat on the sides, brackets on the fork legs and a couple of Dzus fastners inbetween it all to hold the mudguard on. Wont have time to get it done before testing though :-(
Thank you for your inputs guys.

Well I'm back from 3 days testing in Spain and as mentioned earlier in the thread I did a comparison between the 180 and 190 rear.
I started the sessions with the Dunlop GP212 with a 190 rear. Day one was all about running the bike in and learning the track so I didn't go too fast but I did notice the bike was rock steady but turned way too slow. On turn 3 & 4 a right left flick many a time I thought I was going to run on into the gravel as I was fighting to get the bike over from right to left. We dropped the forks through the yokes by another 10mm and softened the high and low speed comp at the rear. This helped massively and now the bike was heading in the right direction and changing lines quickly. Bike held a good line on the fast sweeper but was now nervous down the back straight and shacking it un-checked head as I changed up into 5th. Didn't need a damper just yet. Grip was fantastic and getting the power down never a problem.
So we then changed to a 180 rear. Bike was slower to turn and now leaving longer black lines out of the corners, but lap times where quicker! I dropped the forks another 4mm and got the steering as quick as I wanted it. The bike was easier to flick left/right and drove better with the smaller tyre. Back to the 190 on the same settings I was nearly on the dirt a few times as I over steered.
Verdict time. The 190 gripped far better than the 180 but speed suffered probably down to the mass of the tyre and the extra grip creating more drag. The 180 felt so much better and the bike was easier to change direction. I preferred to slide the bike out of the corners to help tighten up the exit and i think thats why my times on the 180 where quicker. The Cartegena is all about tight turns and short point and shoot sections. Far better suited to the 180. I will certainly be using a 180 on tight tracks and a 190 on tracks with fast sweepers. But if I had to choose one tyre size it would be 180.

great review
I have an 07 d675 running stock forks plus 08 cbr600rr rearshock with 180 rear supercorsas, and I'm oversteering it.
thinking about tweak my steering by sinking the forks under the triple clamp; right now i'm 2mm above it and feels twitchy.

I run my 2010 with Ohlins internals -4 into the triple. We all have different styles. This works for me.
That's exactly the feedback that I was looking into. I would like to stick with the 180 but since the rest of my team are running Dunlops this year in gonna have to switch to the Dunlop slicks and put a 190 on my bike. But as long as I get the suspension set up I should be alright, correct?

I left the Street Triple in Spain in the hands of Woolsey Coulter. He's swapped from Dunlops to Pirellis. Dropped the forks so there's now 18mm of fork above the yoke and with the 180 rear he's amazed at how well the bike is handling.

Hmm that 600rr spring has me interested. That is rated right for my weight with gear on since I am around 180-185lb. Is the 08 600rr shock adjustable? The ebay pictures are shit.
I'm over a second a lap faster on a 190 Pirelli slick than a 180 Pirelli slick at Phillip Island. Ran them back to back on the same day with the same suspension settings and was consistently faster on the 190.
