I removed the rear heat shield today to wrap the rear pipe with glass fibre exhaust wrap, hoping to gain a slightly cooler rear end….fukkk what a job to remove that cover has anyone got info On if it’s worth the effort?

Hoping you can give some positive feedback. I’m going to do the same but I want to ceramic coat the inside and out before I wrap it.

Are you asking how to get the cover off? I recall there are a few bolts but it's going to be really tight to do remove the cover and wrap the exhaust with the rear subframe still on. I removed the seat, fairings, rear subframe and then the heat shield. Also when wrapping it I would recommend doing it in sections.
 
I removed the shield ( big job ) then wraped the pipe then installed the shield again …have not ridden it yet to see if it’s any better I somehow doubt it …it was just a long job getting the cover off to do it and wondering if it will be worth the effort

i've done it wayyyy back. did almost nothing IMHO. was a major PITA to do it, also ended up breaking a spring hanger off after a couple of months due to increased heat stress on the steel under the wrap. not worth the effort
 
I think the heat is in a tunnel of hot air that passes over the rear cylinder and gets trapped. 1st it super heats the tank, and then it squeezes past the seat to heat the family jewels. The rest of the hot air gets forced out through the openings in the rear subframe. I put tape over the holes to try and reduce the hot air from heating the seat. It does not work well. What you see is what I did at the end of last seasons. It wasn’t above 70 degrees anymore so I don’t yet know how well it works.


Ideally it should escape through these opening at the rear of the subframe. As you can see I had an NRC tail tidy blocking the rear exit. Once I realized where the heat was going, I ditched the NRC. Now they are open. The airflow out the very rear is still very poor. I think most of the hot air not heating your balls is coming out of the side of the rear subframe, and THIS is the hot air that burns your legs.

You can’t stop to be hot air, you can only try to redirect it. Ultimately hot air management was not a priority to Ducati, and the design is so poor, it’s almost impossible to redirect. It think this is why so many people say nothing works. A) they are not attacking the main source, B) even if you could attack the source, it can’t be stopped.

The last resort is to cut exhaust holes in the bottom of the lower rear cowl. I’ll take the tape off as I need the heat to flow through the subframe, and hopefully the holes in the bottom cowl will pull the heat away. You know the heat is trapped in this area because the seat gets so hot. Also, I gather the ports on the side of the subframe is the vent spot, but your leg is right there so that’s why the leg gets so hot. Move your leg away from the tank an inch and guess what, the heat stops, it’s getting vented away. Probably need to block the holes on the side of the subframe as well.

Clearly the 1299 wasn’t designed for you to have your legs grip the tank for long periods of time. When racing, you have a knee out all the time, hence, not an issue at the track, in leathers.

If this doesn’t cut the heat off the legs, this is truly a lost cause. It’s pretty much lost anyway. Good thing I actually like my 1299. Lol

Would adding heat shields material, or the high heat reflected exhaust tape help on either the underside of the fairing or seat? Curious if anyone had tried that also?
 
Maybe, just know airflow from 1 heats your legs. (I think). this is not proven. Airflow out of 2 heats the seat. I’m almost certain this is true.

Also true, hot air squeezes past where the front of your seat meets the tank. That air heats your balls. So it’s really three problems to solve.

tbh, heat has never bothered me for a few reasons, its comes with the territory for compact engine that makes a lot of HP so I accept it as a business cost. I ride mostly in leathers and I dont commute or rarely. As soon as you are moving it ceases to be an issue. The bike is reminding you what it was built for, sure you can reduce it but 80/20 rule applies. These are warm rides

Glad to hear it doesn’t bother you. It’s just not the same for everybody.
 
I guess what I am saying is that there is no easy way to reduce heat on this motorcycle, its in the DNA, and a constant complaint for 10 years or more, if you read the heat threads the solution is new cans or new headers or both, ceramic coat or wrap or both, heat reflective tape, gel seats, remove engine covers or add them, add vents, different tune etc- the list goes on then it gets into clothing and so on. The bikes are just hot, some reduction is possible but overall this leopard is not changing more than a few spots. I wear leathers and keep moving, never had blisters or been too worried by heat. If I was Id get something else.
 
The single best thing about forums is people get to discuss ideas to common problems. Forums connect people from all over the world to share ideas. There are likely experts from Ducati and technicians here sharing ideas. That’s the cool thing about coming here.

And yes, it’s a hot bike by design. But telling people to deal with it isn’t sharing a new idea. There are multiple things that can be done, and each might be a small percentage of improvement. Okay. Everyone is different with different motivations. I don’t ride in the winter cause it’s cold, and during this time I do maintenance and figure out ways to make my riding experience better.
 
Yeah I don't know why people think wrapping the headers is going to much plus where is the heat going to go?

Fully agree, the purpose is to share good ideas and discussions. Not everyone will agree and thats cool just be respectful to others.

I've seen some put heat padding or exhaust shield reflective tape just not sure if it helps much. DEI makes several kit popular on other bikes to keep the gas tank cooler and divert or reflect heat away. certainly insulated items help (try grabbing a pan handle without) it's the same principles but heat will rise regardless so have to divert the path away from the rider.

Not an issue when moving however stop lights happen so the search continues...
 
I had it out in traffic in temps of 34c …I have no data or way to read before and after installation temperature
in traffic at stop lights it did seem better, I ride in T shirt and jeans …IMO the tape must allow less heat flow out the pipe, my concern is I may be trying to justify the hellish job it was to put it in, as for it cracking the pipe only time will tell, I do however doubt that as we have been wrapping aircraft exhaust systems for years with improved results in the engine bay.
The titanium and glass tapes would not exist if they did nothing ? I have the OEM shield back on after wrapping the pipe one thing I did notice is the weight of this OEM shield with its stainless liner, I note on other threads that guys have wrapped their pipe and then failed to re fit the heat shield, again IMO that was not clever and then removes a layer of heat protection….think a hot cuppa and a cold hand ..now the same cuppa with a glove
 
The below is from DEI's website on their exhaust wraps "Wrapping any type of exhaust piping is a crucial and important step when controlling exhaust temperatures and reducing radiant under-hood heat by up to 50%. Keeping exhaust gases hotter within the exhaust system helps in decreasing density and increasing the flow of exhaust gases. This improves exhaust scavenging which, in turn, reduces intake temperatures for increased horsepower gains. Also, limiting the radiant heat trapped inside the engine bay decreases heat absorption through the fire wall which keeps dash components and cabin temperatures to an absolute minimum"

I've used this stuff very successfully on cars many times and it helps with radiant heat in the nearby areas for sure but our application for the Ducati is different for sure.

I removed my shield for a year or two because weight, put it back on recently because the bare pipe look was growing old, that's how much the heat bothered me. However riding in 34c is pretty hot, Ive lived in places where its hits the magical 100 (37?) regularly and anything that cools the bike is desirable. As for cracking, mine did so without any wrap at the rear manifold and a very experienced Ducati mechanic told me that it's normal after a few years of vibration and heat cycling.
