HEAT!!!!!!

These things with and without the cats isn't the same beast as heat is concerned.

So are you saying the cats in the exhaust are partially responsible for Panigale heat? Or not?

I’m currently trying to sort my heat issues on my 2012 1199S; I installed the Ducati Spacers heat shield kit just today— will test-ride tomorrow and hope for improvement. I’m still running the OE exhaust and wanting to upgrade to full, but the cost is holding me back. If the consensus is that OE cats in the exhaust aren’t the main cause, then that saves me $2500+.

Bikes with the cats will run hotter.

That’s always been my experience as well. Anybody have a full exhaust system for an 1199S they want to sell?? Lol!

Yes the bike without CAT won’t generate as much heat in the leg area. First time I test rode a stock v4 I rode for 10 minutes and couldn’t get off quick enough it was so hot.

The v4 I bought had akra already installed by dealer and it so much more bearable with no CATs.

Consider having your stock exhaust "de-catted" .Less heat,more noise and much much less $$$

I saw some YouTube videos of Panigale exhaust being de-catted and I wasn't too impressed. The cat is removed but in the example I saw there was no connection made internally between where the cat was to the next section leading to the exit.

The exhaust gas goes from the header through the cat then to the small diameter tube where it loops then exits.

I don't see how this could be good for having proper flow.

Agreed---I'd rather save and pony up for a correct cat-less system--I've seen those cored OEM jobs--they look half-done to me---plus--I'd like to go 70mm!

I watched that Youtube video recently. Really shows how restrictive the stock exhaust is. I agree, just save the money and get a slip on. It looks like Campisi got really nice results with the Termi, sprint & tune.

I just bought a Termi slip-on from Vcyclenut's site. The price is extremely good at $2,025 for the standard slip-on, P08 filter and T-800 so you can apply the Termi mapping.

The Arrow slip-on on its own is cheaper, but add in a high flow filter and a T-800 and you're over that Termi price. I really didn't want to spend $2k but I got tired of wondering if I was on fire when I rode. The heat has been pretty brutal here this year and I actually want to ride the thing.

I watched Campisi's dyno video this morning. Not bad for a slip-on comparing the before and after numbers. I'm not a fan of the blue bands with the Ti system though.

1199 is hot regardless. Full system or stock, won't matter. It might make a very small difference but not noticeable. Anyone who tells you otherwise is full of ..... I've mentioned this in another thread but I'll say it here again.

Engine ice or whatever else will make zero difference in radiating heat
Changing the stock exhaust to anything else will make zero difference in radiating heat
Installing a manual switch for the fan to come on earlier than stock will obviously help keep the bike a little cooler
Heatshields will help very little in radiating heat but it will help
The oem frame heatsoaks like crazy and this is where majority of the heat is felt, inner thigh area
Solution? Change the frame to a carbon one. If this costs too much as a mod, then get the carbon frame covers which will also help.
Do all of the things mentioned collectively, well.... then you'll notice a big difference.

Have you ridden a stock V4?

If you're asking me, yes. A buddy of mines corse. Not long enough to know anything about heat but then again, i replied to a member about his 1199.

I would say that sounds pretty accurate from all accounts. I have never ridden a stock 99 so I can’t speak personally. With the carbon subframe, traditional Akra pipe, programming the fan to come on at 185 and the H2O radiator, I can ride the bike all day (just did close to 400 miles Thursday) and have zero heat issues and that is without any special clothing. I have over 24k miles on the bike and heat was never an issue. The radiator works so well if it is under 80 out, I run an upper radiator block off plate (plastic). I can remove the plate in 10 seconds and store it in the back of the jacket if I need to. It’s a bit expensive to really fix the issues. I have maybe 200 miles on a stock V4. Wouldn’t own one personally.

I thought this was the V4 forum?

Who cares what subforum it is. I only click on new posts and go from there. It's all relative. V4 gets hot as hell too. ALL Ducati superbikes get hot.

My bike is noticeably cooler with the CF subframe…I think the new gearing is making mine run a bit cooler too…it seems to have to pull less hard to get up to the speed I want to be at faster on street riding, I can hold a higher gear and still accelerate hard all the way through the RPM range…so average sustained revs are less and that seems to be helping with heat a bit…it’s also a hoot.

mom gunna put engine ice in it and a line cooler pipe and see if that helps a bit too.

in any case, I road for about 4 hours today and didn’t get hot once…though I suspect that’s due to the CF subframe

makes a lot of sense that the metal subframe thats bolted directly to the engine near the cylinder heads would transfer a .... ton of heat up into our ..... lol

that metal subframe is almost like an an engine radiator soaking heat away from the engine into your crotch haha

Because someone seeking information into heat problems with the V4 could read your post and take it as fact. I respectfully disagree with your stance that exhaust doesn't matter, as applied to the V4. That's not to say heat soak into the subframe doesn't account for misery, I'm sure it does.

I have owned a 1199, a Streetfighter V4 and now a Panigale V4S and the Pani V4S is order of magnitude hotter. I felt the xx99 was hot, but prior to the V4 I never checked to see if I was smoldering. No joke. The Streetfighter V4 was bad and closer to the xx99, probably based on the tuning. But, the Panigale V4 is so much worse.

The exhaust definitely makes a difference. I wrote off buying a V4 after riding a stock one the experience was so bad.
Then I gave the V4 without cats a spin and it was better. It’s still hot especially in traffic, but I don’t feel like it’s actually going to burn me.

I had issues in my V2. I ended up buying Sparco fire proof bottoms which slip under my leathers. At least it doesn’t burn my thigh anymore. Just a thought for you.

The more I read this thread, and from personal experience, the more it becomes clear that the bulk of the Ducati heat issue comes from the metal rear subframe being integrated into the engine at one of the hottest places in the engine.

Ducati’s ingenuous use of the engine as the frame of the bike has a draw back…that metal rear subframe acts like the fins on a radiator, they soak up heat from the engine and transfer that heat directly to you…you are essentially sitting on a big heat soaking radiator blade.

The solution is costly but simple, spring the $2500 for a Carbon Fiber rear subframe…you kill two birds with one stone, you lose 10 pounds or so off the bike, and solve 90% of the heat issue.

SoCal has been in a heat wave and the bike was becoming unbearable to ride, but yesterday after 4 hours of hard riding (went through two tanks of gas) I had no heat uncomfortability after putting the CF subframe on.

I suspect that in terms of overall enjoyment of these bikes, the reduction in heat transfer from those CF Subframes might be a bigger reason to buy one than even the weight savings. Especially if you live in a warmer climate.

A dry clutch, in-line cooler pipes, using engine ice, turning the fan on earlier etc all probably make marginal improvements too, but replacing that heat soaking rear subframe is probably the thing that will make the most difference…I’m going to do all that stuff too just because a cooler engine is a happier more powerful engine and marginal improvements count when added together, but the subframe replacement is the dealio. All those other things may help the engine run a bit cooler, while the subframe replacement will not make the engine run cooler, but it does make it so less heat is transferred from engine to rider.

Anyone know if H20 makes a radiator for the V4S or V4R?
