gday guys,just curious,might be a stupid question but I"ll ask it anyway,being that the guard on the exhaust is steel i assume,would that in anyway be transfering the heat more?would changing the standard guard to carbon fibre make anydifference,what about some heat tape under the seat?? just spit balling here,havent got my bike yet and sort of worried about roasting my mansticles.
cheers burty.

I can't answer your question about putting tape/carbon shield on your bike, but Im sure it would help. I've had the bike two days and have been riding in city traffic. Oil temp sits around 100C in traffic/lights 80 - 90 cruising and It gets warm between your inner thighs. But nothing uncomfortable, however Im interested to see how it goes in summer.
 
I don't think it's the exhaust that's causing the heat. Most of the heat is around your knees, which is well forward of the rear cylinder exhaust. I think the heat comes form the top radiator and maybe a bit directly from the rear cylinder too. This heats up the area below the tank in proximity to your knees and thighs. Above 40 mph its stays quite cool and it doesn't really heat up for single traffic light stops. It only gets hot if you're in slow moving traffic (<40mph) or stationary for extended periods, i.e. stop-start conditions in town, but even then it's not that bad. It's only marginally hotter than my Daytona, however unlike my Daytona it doesn't blow massive quantities of hot air at you when it gets hot and bothered. The panigale exhausts the hot air from its electic fan out of the bottom of the bike rather than rearward through the farings.

One of the reasons why the undertail exhaust went away is due to the excessive heat. Now that the exhaust is way below the belly pan, there is still some considerable heat?
 
I think the main reason the exhaust moved was mass centralisation, but to answer your question yes there is some heat. This is a 1200cc engine with a small electric fan to keep it cool when it's not moving at speed, heat is an inevitable consequence. The cooling system does a good job of keeping the bike cool and it looks like they've designed it as best they can to keep the heat away from the rider. I've not ridden any other Ducati's for comparison, so I can't comment.
 
thanks for the info paddock,muchly appreciated,im used to the heat of the 996. Anyone ridden the 996 can compare??
cheers burty.
 
I remember when I took my 749 out for the first time I said 2 the dealer that it was very hot down there. It was just about a deal breaker, but now I don't even notice it.
 
Test drove it two separate occasions and , the heat was considerably less noticeable the second go around!! Don't be worried!! Forget about it!!

I own a 916. The heat is probably about equal overall. In some situations it seems warmer (around town), in other situations it seems cooler (while riding). Unlike the 916 which heats your butt and crotch, the 1199 heats your thighs and butt. The heat in my opinion is primarily coming from the rear cylinder header loop. Unlike the 916 which builds heat in the mid and rear section of the bike and retains it, the fact the header loop is sticking out in the air, means the 1199 doesn't build and retain heat to the same degree. Unlike the 916, on the 1199 it is possible to get allot of relief from the heat by splaying your legs.

I don't think its coming from the exhaust. Its not your backside that gets hot, it's you knees and inner thighs, which are either side of the rear cylinder and just behind the top radiator.

I agree. Just took mine home and I did not feel heat on my rear. It was all in the thighs. It actually felt good to stop and put my legs down. This was in 100 degree temps with traffic. The bike got to 220 degrees.

Not to discourage anyone but here is a pic of my leg. This was with jeans on. Both sides look like this.

This looks like the outside of your leg? Is that right?? Good grief?? I never ride in jeans so hopefully that wont be a problem but I'm in the South too and we were at 95F plus today so a little worrying?!?!

Inside thigh area. I'm going back out as the temp is down to 89. We'll see if there is an improvement.
 
I just got my bike today and rode 150 miles home, mostly back road 35-55 posted mph.
Outside temperature was high 80's at the start and low 80's at the end of the ride. Bike was 170-215 F.

I was wearing full leathers and bike put out an incredible amount of heat on the upper rear of my right leg. So much so, I had light burn area after I was finished riding home. Felt like a hair dryer blowing on the back inner thigh. Holding the leg out didn't do much to lower the temperature. Going 80+ mph helped. Under that was just incredibly hot. I can't believe this is normal.

Hmmm, so is this heat coming from the cylinder head?

Collected/radiated heat rising up to escape somewhere around your thighs?

I'm sorry I don't have mine yet but just trying to see if there might be a way to reduce or redirect it to vent/emerge someplace else.

Is it coming through the body plastic? Do you think lining the cowlings with a reflective material would help?

Would a bigger fan or the OEM fan actuating at at a lower temp threshold help dissipate it before it gets too hot?
 
LOL - thanks for sharing but I have to laugh -certainly not at your "wounds" - but rather at the face peering out from between your legs.

:D
