Just looked and sat on a new 1125R this morning at our local dealer and was a little surprised to see an oil cooler in the front of the bike right behind the front wheel and kinda low because no one that I remember has spoken about one being on the bike. I did a search here and did not find anything also. I was pleased to see it as just yet another example of a truly "form FOLLOWS function" expression from Mr.Buell. Maybe I just missed it on the 1125 minisite at Buell.com. I'm wondering how many liquid cooled sport bikes have an oil cooler? Anybody? As most have said it looks much better in person, and I for one, really loved it. It seemed to fit me very well and I'm only 5'6" but also seemed to have plenty enough room for a much taller rider. Waiting to demo ride but the weather here is real cold and streets are not very good. My dealer will do this, weather permitting, and has said they usually accompany you. If this does not happen I'll just wait until I get MINE in March. Anxiously awaiting spring. Bob | ||

Most water cooled bikes also have a oil cooler. My Ducati s4rs has one as well as the 1098. Congrats on your new bike!  | ||

Bob, I actually asked a question about the oil cooler awhile back. Is it constant flow or is flow controlled with a thermostat? Never got an answer. | ||

I did not notice an oil cooler on the test bike I rode at Pocono, but I was not looking for one. I am not surprised that one has been fitted, as the bike I rode ran very hot. I was told by a Buell staff member that three fixes had been implemented on production units to solve the problem. I have two questions: 1. What were the three fixes? 2. Were they successful? Anony? | ||

Looking at the bike we have in stock, there are heat shield panels on the muffler, especially in the right foot area. There is a body / cosmetic / heat panel on the right side of the bike, above and in front of the peg, above and behind the clutch bleeder. If you look at the brochure, you can see an engine mount on the bottom of the frame in this area; that is now filled with a cosmetic piece. And the rear header heat shield is different (I'm partial to the "I blend in" black in the brochure as opposed to the silver on the production bike...but that's just me). I can see the oil cooler in the brochure pics, I'm guessing that's not one of the "three". I don't know if the items I listed above are part of "the three" either, they're just what I've noticed on our bike  | ||

I would say most water cooled also use oil coolers as well, fairly common in the later 1900's. | ||

The black heat shield may have retained more heat. Polished stainless would seem more effective at shielding the heat. I do agree that the aesthetics are better on the black shields though. | ||

as I recall from Anony postings...one of the fixes was to go from a 4 row oil cooler to a 6 row....this was to help reduce the heat felt at the right foot I believe | ||

i would also like to know if it has a thermostat. i ended up having a cover stitched up for my firebolts so it would not keep cooling the oil in the cold winter months. | ||

From what I remember that one looks larger than the cooler on the pre-production units...kinda hard to tell on Court's close up picture though. | ||
| Bob_thompson |
Good picture Court, I should have brought my camera with me also. That cooler, which is like the one I saw, sure looks like it has 12 rows, tubes, and I'll bet it does in fact have a thermostat. Looks very much like a Lockhart. Ratbuell, you are correct, my friend, from what I saw with a good detailed look. Getting excited, damn weather! | ||

Yep, looked up some pics of the pre-production bikes and this oil cooler is about double the size of the test mules. They also changed the oil lines - looks like there's a section in them made of rubber for vibration/flex. (Message edited by xb9 on December 11, 2007) | ||

Production:  Thanks to Bueller_bjorn for pic! Nice to see enhancements like this on the first production bikes! All that Inside Pass track time payed off! (Message edited by xb9 on December 11, 2007) | ||

i remember seeing that one of the reasons for the delay was something to do with the oil cooler. | ||
| Ustorque |
not to get too far off subject, but i just noticed in the pics above that thing has one hell of a hunky sidestand. and was curious how it feels compared to the XB's? | ||
| Xb9 |
Looks beefy but it's light weight and made of aluminum I believe; worked great on the pre-production bikes. | ||

Heck, my 1974 Ford Gran Torino had an engine oil cooler, tranny fluid cooler, and even a power steering fluid cooler. I recall it too had a radiator. tee he he If you look at the 1125r on the brochure, (surely printed months ago) its pretty dark and in the shaddows, but an oil cooler is there and I recall it on the bikes Labor Day week in Salt Lake. Whether it grew in size or not, I can't say. My photos lack sufficient detail there. I also doubt an oil cooler, on a water cooled bike, will lower exhaust manifold temps significantly - especially only going from 4 to 6 rows. Now, the manifold right side air scoop, it routes air from around the pipe in front of the riders leg inside the chassis. Also added is a piece that fills in below the pipe next to the riders foot and ankle, conforming in all sorts of odd fitment, probably preventing heated air from escaping on to the riders boot. On to other things, this bike is so smart, it has a code you have to enter in order to start the bike, (if enabled) and too many attempts to guess and the whole thing shuts down. PIN is entered using display Toggle and Mode buttons. MPH & deg F, MPH deg C and KMH deg C units can be used. Regular service maintenance requirements come up on the ODIS, on-board diagnostics information system. Among expected display info, coolant and ambient temperatures are displayed, average & instantaneous fuel consumption, current lap time, difference of current to best, and 99 lap times are available for display too. Now the hard part, first 300 miles keep engine under 6,000rpm, up to 600 miles keep the engine under 7,500rpm. Also under 600 miles, don't lug the engine, brake easy and don't maintain a steady engine rpm. | ||

Why would you need a thermostat for the oil cooler on a liquid cooled engine? Isn't the thermostat for the coolant supposed to keep the engine at a somewhat constant temp anyway? (dodging sticks and stones) | ||
| Jajarm |
Did anybody else notice that the oil cooler lines are reversed between to the preproduction bike and the production bike? Top line to the rear port vs the front port. Just pointing it out. | ||
| No_rice |
why should it be cooling the oil when the engine is trying to warm up? it doesnt cool the coolant when its trying to reach operating temp. (Message edited by no_rice on December 11, 2007) | ||

Muffler welds sure look worse on the production bike, I'm guessing photoshop. |
