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.
180 vs 190 Rear tire size?

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.

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.

Yeah, I have a 550lb spring on the stock gen 1 rear shock and it was an improvement over stock but the 600RR unit can be picked up for like $50 on ebay. Has me interested now...
I see that the 600RR and 675 rear shock length is 293mm eye-to-eye. I also see that the 600RR rear spring is 11kg/mm (615lb) and the 675 rear spring is 12.6kg/mm (705lb) stock.

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.
Yes! I run the dunlop slicks as well as a few other members. Best tire I have been on.. They freakin rock!

Have you tried the UK version in the 195/65/17 & 125/75/17 size? After I burn through this set of Supercorsa SC's I have for my next trackday I am considering the D211GP or NTEC slicks.

mine is 08 and is fully adjustable.
Yes.. I have run the 190 UK ntec Dots, 195 slicks and US 200 slicks.. I have also used moto 2 slicks.
Ask BMO on this board as well. I made him make the switch and he has thanked me numerous times...
I can't tell a difference between the 195 and 200.

The photo was before we dropped the forks. Must have been a day 1 pic.
Okay, I ordered an 08 and it doesn't fit because the bottom monoball mount is too wide by probably half an inch total. How did you get it to fit? I'm hesitant to grind on the shock.
