The new SP V3 is even better but will require a big change in setup. If you need help, lmk...
Can you tell me more about the pressures you're running? I usually run 30.5R/31F but you're running much different ones. I run Michelin 2CT on just about everything other than the SL so this is definitely going to be a bit different.

I weigh 170 lbs without gear and I couldn't get comfortable on this bike at all until late last year I took out basically all of the preload to get the sag right. However, that was basically at the start of the season and I haven't had much of a chance to ride it this year.

I go pretty well on the track with all of my other bikes but the SL is the one bike that I need to learn a bit and that's why I think I need to do a few track days on it.

I Ride: 16R; 18 R1M
These were Pirelliís latest recommended cold and hot pressures last season.
Unlike their recommendations of 31 hot for the front, my Pirelli guy had me running 33-34 hot up front and the tire worked better.

Hope this helps some.

Thanks from able duc and Sherpa23

@Sherpa, with the SP V2/V3 oem tires you can set the front at 33 (cold) and the rear at 26 (cold), no warmers. If the temp is 75F OR ABOVE and the sun is out then all you need is 1-2 laps and the tire will be ready to go!

When you come off track check the rear and if it has gone above 29 PSI then bring it back to 29 and check the rear one more time after your next session; if it has risen bring it back to 29. Repeat this process until it does not rise above 29 PSI and then you should be set for the day.

IF the sun isn't out or it is colder then you should run the cold pressures +2 PSI in the rear until it gets warmer and then repeat the process above.

The front will rise about 1 PSI but if you start with 33 then you really don't need to worry about it; few people brake hard enough to generate a rise of more then 1-2 PSI (if already inflated properly).

If you use warmers then 34 front (hot) and 28 rear (hot) off the warmers should be good. Once again, check the rear immediately when you come off track to stabilize the pressure.

WHEN the rear tire pressure rises above 29 PSI hot they tend to get "greasy" which means the tire will move around a bit more on throttle. Not a bit deal but you don't want to create a tire tear.

This advise works, if you follow it you won't have any issues IF your bike and rider sag are set properly.

I recommend 25-30 bike, 38-40 mm rider on the fork and 10-15 bike, 28-30 mm rider on the shock. Sag is VERY important and having the right spring on the bike makes all the difference. 170 lbs w/o gear should be fine for the shock but I would recommend .95 N/m springs in the fork. These are about $150 plus install and any shop should be able to install them easily.

Keep in mind the SL, like all single-sided swingarm bikes has an ideal ride height/swingarm angle that can only be properly measured with the Ducati ride height tool. Unfortunately, most dealers don't have it...and ride height can be affected by chain tension, chain length, shock length, gearing, overall preload and tire size.

The 1299 SL has an issue with tire warmer to header clearance that apparently no one else noticed. I did point this out to the lead engineer when I was at Mugello to ride the 1299 SL but they didn't seem to care.

I do have a solution if anyone runs into this problem....

This is super great info. I actually don't plan on using warmers on this bike so this is perfect, including ambient temp info and such. Thank you!

A cheaper alternative - i just picked up the Supercorsa TD - the tires are amazing - they are less money than the SP and offer more all out grip. You can buy them here - I got mine from a Pirelli dealer for $359 mounted and balanced.

@1299rFE, you are totally right! The new TD is quite good and meant for this exact application and it comes in 200/55! I actually have a couple sets. One for my KTM 690 SMCR seen below



and another set for my SL or RSV4. Not sure why I forgot about these, lol...go get em!

Nice 690!
How is the warm up on the TDs? As fast as the SPs? Mainly to be used for canyon carving.
