What are the latest tire options - brands & sizes?

[abhijitz]

The Pirelli Rosso II 140 Rear + 110 SC1 front was a common setup when i raced 2.5 years ago. With many small displacement bikes hitting the market, what are some real world track feedback on new tire manufacturer/size options? [only looking for trackday/raceday tire options/choices]

Bridgestone Slicks? - what size combination is the "GO TO" setup for 250s and 300s. [Now that slicks are legal in production class]
Bridgestone S20 EVO - saw a great video review from Ari & couple of threads below someone is trying, but yet to see any feedback posted.
Dunlops - Do they have race slicks for the small displacement bikes?
Any other choices?

Hoping to come back and race, most likely on a 300.

PS - i am mid-pack paced on a "stock egnine" 250. {1.59 at Sonoma/2:13 at Thill race pace}

Maybe not directly helpful for the 300, but I had the S20 Evo on my ZX6R and I have them on my 796 and I really love these tires.

They grip really well, and they're extremely stable and predictable in cornering. I have had other tires and it's probably just personal preference, but the S20 Evo gives me a great deal of confidence compared with other tires I've ridden on.

I recently swapped my Pirelli Diablo Rosso's out on the 796 for the S20 Evo and it transformed the feeling from flighty and edgy to stable and reassuring.

First upgrade for a 300 I would be getting would be either S20 Evo's or BT-003 RS's.

Been on track with the SC1/DRII the last two events and can't figure out whether I like them better than the 003Pro/003RS combo. I think the Pirelli's have better outright stick but the 'stones felt a bit more stable.

Race tires options are now

'stones: GP slicks, R10/003RS
Pirelli: SC1/SC1 or SC1/DRII
Dunlop: A13/A13 or GP-A/A13 , 125GP slicks
Michelin: nothing?

Motorcycle USA recently had a huge tire roundup, and the Pirelli's and S20's are both in the review. Seems like the standout aspect of the S20's is their stability, and the only thing they're slightly short of the best in is the road feel, slightly less than the Pirelli's and Q3's.

Are the GP slicks is what most CVMA & WERA guys run? What size are they.

I think 125 gp slicks are 95/115 in dunlop and 90/120 in bridgestone - I think its a mixed bag on who runs what

I was told by the Pirelli rep 2 weeks ago they are very close to releasing a 140 super corsa

I'll be racing with the S20 Evos this weekend. I'll update my thread with my review after that.

I had very good success with the BT003RS tires.
They did slide around a little towards their end of life, but were predictable and controllable.

They held lines well at race pace and even were comfortable in the rain.

^ I have the same experience with the dunlop A-13s that he has with the bridgestone's

except the dunlops track the same all the way to the wear bars, I didn't notice any traction differences during the entire life of the tire and am comfortable running another race day on them before I retire the tires

Rain grip is good, I touched knee on a wet day (granted it was drying out at that point) with no issues. Ideally I'd run proper rains in a rain race though
