My panigale cooks my legs

PannyofDoom · Jul 16, 2012

My Tri has gotten barely any use because of this. I bought it mostly to be able to ride with my wife on the street, but it is FIRE and terrible to ride. I'm 6'6" 260, but have large thighs that must block all heat. I put 300 all track miles on it in the 2 months I've had it. Just loaned it to my Ducati mechanic and he got it up to the first service in 3 days, but also probably won't buy one after feeling the heat.

I'm too upside down to trade it in, but I KINDA wish I had just gotten a Multi. Best for the street and still trackable.

AMAZING on the track with no heat problems, but I have a track bike.

I have Termi slip ons and no wrap. I get no burns and it gets over 100F here. How are you guys riding that this happens? I mean I get hot, but damn?!

Damn dude you need to get some sun hahaha! j/K

It's my thought that most of the heat is radiating out from the rear pipe and metal guard under the seat. Some are saying the vertical cylinder but it's not that much closer to my leg than my streetfighter, or any other duc for that matter.

THough I'm fortunate in that whatever reason the heat is not an issue for me. I've ridden for up to three hours at a stretch without any problem.

I'm getting an extra metal cover (thanks Allan "sooner nation") going to have it jet hot coated, then going to line with the alum reflective foil and see if that makes a difference. As the one member here posted the engineer friend did heat tests on before and after pipes and noted a major difference in heat. Won't cost much and thought I'd give it a try.

Also, don't despair guys. Mike at Motowheels.com said they're working on something for this so keep your eyes out for word on it. Dunno what it is.

Yep - I had my Termis pipes Jet-Hot coated and just finally got them mounted.

There is a significant difference in radiated heat with the coated pipes.

I am about to go outside an take some pictures so will post them shortly...

obviously this has more to do with people's sensitivity and tolerance to heat than anything else. clearly there are those that get a lot of heat against their legs and they can stand it and clearly there are those that feel the heat and their skin doesn't react well. everybody is different. me, when i don't wear the right gear, the heat gets so hot that if i force it, i could be ejected from the bike if i'm not careful. so i take the proper precautions. clearly we have members here that can ride the 1199 in shorts....but not me.

6 feet tall and not suffering. Wayyy better/cooler than previous 1198

As a previous 1198s Corse owner I can certainly attest this bike is MUCH better in the heat area! I just don't understand what it is that people are having such issues with, and on this poor guy its on his LEFT leg too which is very odd!

I wish they would come out with something of a good looking for the problem (that I dont have) and I do like the idea of this "Jet Coat" thing with colors, but does that truly reduce the heat? IMHO I just think that "heat wrap" looks like a ghetto machine with all those irregular joints and kinks. It's a 38k bike for heavens sake - but ya gotta do what ya gotta do I guess, if you have an issue.

Err

zvez · Jul 16, 2012

a post on here a fellow had his pipes analyzed by an engineer friend who analyzed heat before and after and it was a significant difference. Don't know where the post is but it's a good read.

No bike I've had as been as bad as my 996, in leathers, I've got scars from teh burns I got from the right side vertical piple that is only a few inches from your right leg.

Here was my post:

And, neither he nor the numbers were wrong - I have noticed a significant difference in radiated heat.

I was traveling so haven't had a chance to see if my friend was able to convert the data into a readable format suitable for posting.

I have to say the one thing that doesn't seem to hold is the cool down rate. Those pipes are still effing hot 10 mins after shutting the bike down.

So, I finally got my headers back from my thermodynamics engineer friend at the Naval Postgraduate School.

If you recall, I let them take some header skin temperature measurements prior to sending them off to Jet-Hot for their polished 1300 coating.

Well, after I received them back from Jet-Hot I sent them back down to my friend for some post coating comparison measurements and I just received them from him today.

While I don't yet have the chart with the actual measured data (waiting for the E-mail) he said the difference varies by EGT (they tested at 400, 500 and 600 degrees F) and header segment. Though he did not fully assemble the header, he tested each segment individually and skin temps for the individual segments varied no more than 13 degrees F at the target temps. The segments cooled at similar rates with the two longest segments cooling faster than the shorter ones.

They used a heated gas source (propane, I believe, but I'm not sure) jetted through the individual header segments to generate the desired EGTs, pressures and velocities. I don't recall the actual internal pressures or flow velocities but they'll be in the chart.

The segments were mounted on a non-conducting (thermal neutral ceramic) mount with unobstructed flow in/out. Ambient temp in the test chamber was controlled to 75 F and external air flow was 15, 25 and 50 MPH.

-----
External skin temps averaged about 57% cooler post coating and were (measured) at: 168 F at 400 F; 218 F at 500 F and 259 F at 600 F. He tested each segment for one complete cool-heat-cool cycle with 10 mins at each target temperature.

Cool down was 78 % faster at 75 F ambient chamber temperature, 0.0 mph external air flow, no heat source, ambient internal pressure and 0.0 internal flow velocity.
-----

I'll post the chart as soon as he converts it to something I can use and post and I'll correct anything I've posted here should I have missed anything or screwed up the values I wrote down during our conversation.

I'm pleased with these numbers. I spent $195.00 for the coating. It took 9 days total including shipping time and they look great! There is no discernible dulling post test. I'll get them installed on the bike hopefully later this week and post pics soon thereafter.

I'm going to upload pics of the header as it is today in my pictures folder. COATED TERMI HEADER - Ducati 1199

Gunny Fitz · Jul 16, 2012

There was the one using infra red camera too which was cool and showed exactly where most heat came from!

iiiofiv · Jul 16, 2012

I posted another item related to heat and cooking but haven't seen it and can't now find it.

It is related to melting of the cooling fan housing.

I'll keep digging and post those pics too.

iiiofiv · Jul 16, 2012

Here it is -

WARNING:

Check the housing for the cooling fan for melting. It's located at the bottom of the bike forward of the oil sump and just aft of the lower radiator in a black housing.

When pulling parts off to fit the full Termis pipes the tech and I noticed a good bit of melting had taken place on the top right portion of the cooling fan housing. We inspected two other Panigales there for their first service and both of them also had signs of melting.

The shop took photos and are going to contact DNA about it. Here are the photos:

Since I was pulling the stock exhaust off and no longer had a need for the exhaust valve or its actuator which has a pretty decent reflective heat barrier glued to it; I pulled that barrier of the actuator motor housing and attached it to the cooling fan housing right over the melted area.

I can imaging over time this housing melting completely through and possible damaging the fan itself since the plastic would have dripped directly onto the fan blades. Worse yet, it could get sufficiently hot to actually ignite - and we don't need any more Flamigales on the roads.

Just a word of caution - will let you know what DNA has to say. The dealer ordered a warranty replacement of the fan and housing for me. Though mine was not melted entirely through - it was not far from it.

I had a day where I got caught in some traffic in a small town I had to go through. I was on my 996 and it was 40c-104f and humidity was 100%.
It wasnt so much the heat from the bike that got me, but the heat I was suffering from inside my leathers. So if the heat from the 1199 is no worse than this then it is no worries.

Thanks zvez that helped me to understand a bit more on this subject.

A classic case of heat rash. Everyone has a different tolerance level which is why some get this and some do not.

iiiofiv · Jul 16, 2012

Here is the link to my photos on the forum.

COATED TERMI HEADER - Ducati 1199

This folder contains images of the coated pipes uninstalled and then installed.

You might note a brown sort of speckled look at the front of the horizontal pipe - this was over spray of Honda cleaner/polisher that got on the hot pipe.

I just went back out and with a little bit of Dawn dish detergent in warm water and a clean cotton cloth washed it right off with no dulling or scratching at all.

I'm sending my stock pipes off to Jet Hot to have them cleaned and coated as well and put them into standby in the garage. Might experiment with some color on these.

One very important thing to note if you decide to go with coating your pipes: have them tape off or otherwise protect the areas where the pipe sections join. Fine to coat them but be prepared for a bit of extra work sanding these joints down a bit to get them to fit. Lesson learned the long way. AND - test assemble them PRIOR to beginning installation - it is a PITA to take them apart (if you can get them together) once they're on the bike.

Actually, it was HOT!!

flobrandx · Jul 16, 2012

I ride in jeans and the heat comes and goes for me but it's not unbarable by any means. I feel most of the heat on the right side, not much on the left. I'm sure each persons riding style, climate, physical size, and tolerance all play factors to the heat issues.

2012DUCATI1199 · Jul 17, 2012

The bike DOES ride hot. But , up till the other day , I thought everyone that was complaining was just being ........ Well , I went for a ride and was cruising around 85mph , and my inner right leg felt like it was burning. Turning my knee out didn't help. Got home and looked , and had a deep red mark on my leg. I was ready for this in stop n go traffic. But at 85mph ! ? Crazy ! Guess I'm a ..... to. LOL !
