Fuel Moto reported testing the 2010 Touring bikes and finding a 150 degree increase at the head pipe over 2009 and earlier models! Aren't the head pipes running about 350/400F on 09 and earlier bikes? That would run them up to 500/550F! WOW!

I believe the elevated temp was attributed to the catalyst being in the H pipe and stricter EPA regulations. They reported the extra heat on the driver as quite noticeable over the 2009 Touring bikes!

A motor and exhaust system with that much extra heat to dissipate doesn’t sound like a good thing to me.

I thought I would ask whether you guys with 2010’s agree or disagree with their statement?

Thanks much, Bob

 

I can't say, I put the Crotch Cooler on my 08 Ultra, and heat is no longer an issue. It works great and after I mounted some skulls on it to go along with the theme of the bike it looks good. I'm very satisfied, Thanks, Capt-Itch!

 

I rode a bunch of 09s before I bought my 2010 Road King.

I thought the hottest ride was the 09 Ultra I rode for about a week. Most likely due to the lowers and wind vents that the other bikes didn't have.

My 2010 doesn't feel any different from the other 09s, even the 09 Road King.

Not saying I disagree because I haven't actually measured the temps myself, but seat of the pants feeling is the same.

 

I did multiple demos (at different dealers) on 2009 and 2010 Road Kings and Street Glides before I ended up with a 2010 SG, now I'm no expert but I didn't notice any difference in the seat of the pants feeling.

 

Made no difference for us left-coasters. We've had cats all along....

My right leg will confirm the hot temps, however. I've got two huge oval shaped scars from riding in shorts and hitting up against the pipe. Lesson learned, never ride the '10 in shorts. My '04 RK Custom never was that hot.

 

What is a crotch cooler? I have an 08 EGC wouldn't mind cooling it down a little.

We own both 2009 and 2010 bikes and there is certainly a difference in radiant heat from the exhaust pipe which can be easily measured. I personally log many miles on both bikes and the catalyst equipped 2010 bike generates signifigantly more heat, this is how a catalyst is designed to work. This is not so apparent when moving but more so when stationary, especially in warmer temperatures. This is also influenced by engine load and we have to be very careful when testing on the dyno not to overheat it as we can turn the catalyst red hot in one 15 second dyno run and this is with a 2500 CFM blower on it to keep it cool. I have also seen firsthand as well as seen several threads here and on the CVO forum where the collector was red hot at highway speed. Remember the core of the catalyst in the collector is designed with an operating temp of approx 900-1400F and there is simply no way the pipe can run as cool as on the 09. Regardless of the heat the 2010 is a great bike, with comparable performance to the 09 and the extra heat does not really bother me, especially considering I have been riding it to an from work in 40 degree weather this fall.

 

I don't find the heat objectionable on my '10 Ultra. After coming form a thigh-broiling '07 this thing is downright cool to me! I get a touch of heat on my right lower calf and ankle. Changing foot position alleviates it. I notice nothing objectionable when my feet are on the ground though. Haven't had the EITMS kick in yet so I may change my mind once I see some warmer weather. YMMV.

Yeah. It's really hard to make a determination right now. Come next July we will be seeing lots of posts about it just like we did on the 07 models when the TC96's came out.

It should be interesting to see if anyone can come out with a solution to this other than new pipes without the CAT.
