Hello friends. I need some help with the suspension. I am riding a 2012 Panigale S with electronic Ohlins. I use stock settings on race mode. I am 85kg / 190lbs with gear.
My problem is that when I stop at start/finish on Serres racetrack/Greece my forks hit the bottom and for a second I feel that my front wheel is sliding. Should I increase compression ?
My second problem is the rear shock. When I lean I feel like my rear is jumping. The wear on the tyre comfirms it. I reduced the rebound by 1 (8 to 7 if I am not wrong) and its a little bit better. Also I fixed my tyre pressure and now there is no wear that can confirm the jumps on the rear wheel. Some ppl in the next box told me that my shock is very hard and I should make it softer. The only thing I could do is to reduce the rebound. Should I change the compresion or adjust the shock with the wrench ?
P.S. My rear sprocket is +2 (41 teeths) and my rear tyre is 200/70 dunlop.

then take the electronics of top of forks and set your sag properly
I dont know what this means. If im coming in hot off a long straight, and im on the front brakes my ABS will kick in but the rear of the bike does bounce a little with a good set up.
Going in not as hot, and I get no hop.
Why? raising the rear that much may be the cause of your problems. stick with the 200/55 and enjoy it

@SuperDomestique each spring rate is good for 20 lbs. You are two spring rates away from ideal weight; what the bike's delivered spring rates are. 8.5 N/m in the fork is pretty light. I would recommend starting with a 9.0 in one fork leg and 8.5 in the other in the pressurized fork. That is the 2019+ V4R or 2022+ V4R fork. Let me know which model you have.

@Power4Gear you have a lot of issues going on. Please list ALL changes to your bike here and where your bike's current settings are for bike and rider sag as well as rebound and compression settings.

Was this after spring changes or with stock rates?

This is with stock springs both front and rear. Front preload is 0 mm of 15 (3 mm stock) so no preload at the moment. Rear preload was adjusted to show 10 mm thread (18 mm stock). Stock preload per manual were different from what was on the bike from the dealer (9 mm front, 11 mm rear).
Suspension settings for last weekend's trackday at Thunderhill West was Sport Dynamic (default). Bike felt great in the corner. Very predictable and confidence inspiring. Thunderhill West is also not the best track for this bike. Basically was in 1-2nd gear the whole time.

@SuperDomestique and you weigh 147 lbs WITH gear? Your sag numbers seem quite impossible with stock springs. I would recheck bike and rider sag accounting for stiction. Also, if I set up the bike I would be using lighter springs front and rear. Where are you located?

@roadracerx Outside of setting the sag, what do you recommend for a base suspension setup? I'm on a 2021 Panigale V4S. Rider sag is set at 40mm front and 30mm rear with 11.0 Nm fork springs and a 105 Nm shock spring.
I've done two track days and am starting to get more confident.
Do you prefer DES set to dynamic or fixed?

I'm also at the standard OEM shock length with factory gearing.

Wrong direction on the shock. Also, why would you make a bike this powerful more peaky with the increased gearing ratio?

@roadracerx personal preference not to use 1st gear, but rather gears 2-6. It also depends on the track specificity - doesn't mean bike is more peaky. Regarding shock - wrong direction for you, right direction for me. Bike is hard to ride with 312mm+ rear (corner exits, braking - terrible).
