I am running the stock Pirelli Supercorsas. I'm prone to keep running those as yes, the bike was designed around that specific tire.
YOU really need to try the Q4s, much of what you are complaining about is your set up combined with tires and pressures.
Are other 1199S owners successfully running in dynamic mode so the suspension is actively adjusting to the current road conditions?
Most run F
I'd advise a bit of binge watching of Dave Moss
Sage advise, I see him every track day, and they guy knows this better then most anyone you can find in public
The stiffness of the xx99's is great on track where the harder you push the better you feel but the bike is hard to dial in.
This bike was easy to dial in, you set sag, you set suspension rebound and compression front and rear, set tire pressure 30F 29 R and ride it. Takes very little dialing in after that. less tire pressure for different track temps.
on the track I'd start 30/30
sage advise iim only 1 lb less in rear. But I wanted to add these pressures also work great for the street and canyons
I'd like to hear from other 1199 riders ("S" or otherwise) who are experiencing the same thing--or possibly the opposite?
Just the opposite for me, but I go between a multistrada pikes peak and my 1199S. Ive run both the SC and the Q and the SC's have a sketchy feeling once they get past the 40% worn mark. As to where the Q3 and Q4 give you that mid corner stability you are loooking for.
I'm wondering if the bike is prone to crash, in its stock settings.
YES it is. Its set up for 2 up and there is almost no rear sag. Setting sag is key, 30R and 35F and honestly at your weight the bike is under sprung. You could contact dave moss and he will advise on what you need. You can dial in the DES to compensate for the lack of springs but its not the same as having proper springs.
Well, I don't ride on track with Street tires. Really a bad idea IMHO. Get the proper tires, and a spare pair of rims, if you want to do track days.
I think once you are a fast A rider sure. sage advise. Anything under that and its over kill IMHO. But with that said I would only run the best tires designed for street/track days. Love my Qs and for a slower A rider like myself SC's or Mich, or Q's or Ps have been working well enough. We dont really loose to much grip shoving into the tights stuff while scubbing speed off. The SCs we average 3 track days, my Qs will make it 4 that are on there now. The fast A rider,s we hang with that runs tire warmers and slicks gets 1 to 2 days depeding on temps and choice of which SC slicks their is using. We run mainly Thill, Sonoma, Laguna
