I pretty much set up my bike for Pirelli tires now, with the 180/60 rear. My setup seems to work pretty well for me now. Got a good balance of stability and agility in handling.

I haven't noticed what you're talking about with the rear tire. I have seen it in pictures, like the one PSlo posted on a different thread in the past, but my rear end seems pretty stable when coming out of turns so long as there's plenty of rubber left on the tire. If they change that, it'll probably mean it's going to be a stiffer carcass...more Dunlop-like...hopefully not to that extreme though. Means people that mount tires will also bitch a bit more since right now everyone loves Pirellis because they're the easiest tires to mount since they flex so much

I don't feel it either and I've seen some pics of me where the rear looks damn near folded over the rim on corner exits. It's not going to be extreme like the carbon fiber dunlops. Just a bit more than we have now from what my tire guy said today.

BTW, do you mind sharing your geometry setup? I've got 8mm of shims in the rear shock (ttx) and the forks are flush w/ the tubes (ohlins inserts). Heard some others that go stock rear ride height (339mm eye to eye?) and flush at the front. Seems like a Hell of a difference. Any input would be appreciated. I'm getting faster and trying to dial in my bike before it puts me on my ass too hard.

Mine's pretty much the same as what you've heard. I feel like that setup would be twitchy as hell. First off, I should mention, I have a TTX as well and also have Ohlins cartridges in the forks which increase the height (length) by 10 mm from what I've been told. The rear was set as stock length (right around 339 mm), with no shims at all. Not sure why you'd bother with shims anyway since the TTX is height-adjustable. The front height was 5 mm when I got it and my bike always felt too twitchy and was getting lots of little tank slappers coming out of corners. I raised the front up to where the forks are now flush with the triple and that made it work a lot better. So relative to mine, your current setup sounds like the bike sits higher in the rear, meaning lower trail. Of course the way your suspensions are setup matters as well, it's not just the geometry. Your suspensions are what drives the amount of squatting the rear does and diving of the front, so it may not necessarily mean it's very twitchy like mine was.

Nope, didn't notice that at all

I am running max length of the shock (k-tech based off of TTX) and actually running about 3mm above the front forks by using extenders.

Any trouble touching your feet on the ground with the bike so tall? I'm tippy-toeing with my 30" inseam with my stock shock 339 mm eye-to-eye and shimmed 6 mm, and Racetech Goldvalved forks (15 mm longer than stock) run flush with the top of the triples.

The bike handles awesome, but I hate "tippy-toeing!"

I'm on my toes a good bit too but I really don't mind. If Pedrosa can do it, I shouldn't bitch about anything!

Because he's got 2 people to catch his bike. This is what happens when he's on his own

@PainfullySlo w.... what pressures you running in above photo ?!!

I just got 180/60 for my 2014 bike, just getting around to setting it for track but i'm assuming i wont have to put in the 8mm spacer in back shock using this size ?....

Got an SC0 180/60 on the rear right now. Bike seems to fall into the corners nicely. Don't think I'll be keeping it though as (stated above) it's drastically changed the geometry. Going back to the tried and true S21s once I've got another day out of it...

So change the geometry. That is a much better (grippier) tire than the S21. Probably more grip than you need though. I'd love to try out an SC0 just to see if there is noticeable difference between that and the SC1. The SC1 already feels sticky as glue! Supposedly SC0's don't last more than like 2 races at really fast pace. So probably 3-4 races for me

I would but I'd just got the bike setup well for the S21s. The intention was just to see out the remaining track day with the SC0 as my S21 had no tread left. Did the job. You're right, sticky as hell. But I am going back to S21s as I am not at your level, plus I had to ride the thing home.

You ride to the track??

Yeah, what my coach said. But I'm not a racer yet.

So? That has nothing to do with it lol. I was towing since day 1 when my bike was a street bike. I rented a little trailer for like $25. I think in the time I've been doing this, I've seen 1-2 people ride to the track...out of thousands!

Racer or not, you can still crash just as easily...hell most of our crashes are in the novice group where most people are riding street bikes. What do you plan on doing when you crash and the bike is damaged enough that it's not rideable then?

He's right you know...

Then again, I've crashed my race bike and couldn't drive my car home so there's that too.
