Ducati Panigale S model

Ducati Panigale 2012 S Model test at Thunderhill Race way Park, CA 5/22/12

Ambient temp 85F, track temps 115F

Bike owner: Alfonso Loera at 170lbs

300 miles on the odometer, OEM tires, no gearing changes. Bike set in SPORT mode for the day.

 

Chassis:

Forks set at stock height, no geometry change (+8mm)

Fork preload left – sag in the ball park at 40mm

Fork rebound set to 23

Fork compression set to 25

 

Rear shock preload not changed, rider sag 20mm plus 15mm free sag for 35mm total sag

Shock rebound set to  14

Shock compression set to 17

Rod position not changed to the rear shock.

 

Cold tire pressure on the Pirelli’s set to 25psi rear and 27psi front

 

 

Session 1:

–       scrub in new tires to the track, check hot pressure, get the suspension hot and reassess sag and damping. Alfonso indicated the bike was very bouncy.

  • pressure gain of 5psi rear and 4psi front
  • sag remained unchanged
  • fork rebound changed to 15
  • shock rebound changed to 12

 

Session 2:

–       assess changes to rebound and see if the chassis settled down in the long turns

  • fork rebound 15-17
  • shock rebound reasonable based on rear tire wear
  • rear tire showing compression too stiff, changed to 15

 

Session 3:

–       assess acceleration on the rear tire wear to see if the compression change helped the tire and to make sure that the front end pogo was gone (use tire wear to assess)

  • fork rebound better, but possible improvement at 18 or 19?
  • Shock rebound to 10 due to topping out movement on deceleration

Final settings:

–       stock fork height

–       fork rebound at 17-19 best range

–       fork compression at 25

–       fork preload unchanged

–       shock preload unchanged

–       shock rebound at 9 -11 best range

–       shock compression at 15

 

PIRELLI TIRE PICS:

 

Front left:

Note: the fine lines on the tire where braking is heavily applied as the bike is tipped in to the corner. Those lines running perpendicular to the tire show solid braking technique and underscore the need to experiment with fork geometry.

Front right:

NOTE: braking wear marks are not as well defined on this side of the tire due to track design at Thunderhill. Rights are survival/throttle management corners.

Rear left:

NOTE: The sipes are not deformed where the rider picks up the throttle in the middle 1/3rd of the tire. On the outer edges, you can see very small rubber balls on the upper edge of the sipe where there is no throttle control on the tire due to braking into the corner.

Wouldn’t you be careful with a brand new bike?

Rear right:

NOTE: how smooth the surface of the tire is. A combination of good rider with a smooth throttle control and suspension optimized to the individuals riding style.

Thank you for the opportunity to work with you Alfonso on your bike – we achieved a lot in a short time thanks to the open day format with Erich Frech’s ride when you like track day
