Have just finished three wonderful days in the Deal's Gap area of NC/TN, and finished up with a Dyno run at Wheeler's Performance. I have had several bikes dyno'd there, so thought it would be interesting to compare them. All of my bikes have turned low compared to magazine ride reports, and my friends have had similar results at Wheeler's. I suggested to Ken that he has a 'slow' dyno - but he prefers the term 'accurate' instead. At any rate, from Wheeler's Performance at Deal's Gap, 2100' altitude, the results: 125.2HP/71.67ft-lbs torque, with the April '08 reflash. Max HP came at 10K rpm, max torque at 8200. To help put this in perspective, a stock '07 1098 put down 128.62HP @9600 rpm, and 72.81ft-lbs @8200 on the same dyno. Top speed at the limiter in 6th for my 1125 was 164.9mph. Ken does a lot of dyno runs, but this was his first 1125. He commented that this was like no Buell that he had ever seen - that it was putting down power like a Ducati. I asked him if he had a 1098 in his database, and if we could pick a stock one to compare to my bike. The results were overlaid on one of the sheets that he gave me. I think that the board will find this interesting. As soon as I get home I will scan them, and email the file to anybody here who can help me get them on the site for others to see. The most striking difference to Ken was the shape of the torque curves, and the advantage this gave to the Buell in the low and mid-range. My bike built smoothly from 3k to 5k, and was relatively flat from there to 10k. The Ducati has a hole from 4k to 6k, and does not catch up to the 1125 until 7500 rpm. From 7500 to redline, the curves are very, very close. I was hoping to see something in the mid 120's on Ken's dyno. I suspect it will be higher when I get around to having it done at my dealer in Pensacola. I was also happy to see that Ken was impressed. It wasn't what he was expecting. Jack | ||

Brad Hardin, from Smoky Mountain HDB in Maryville, TN, came over to me while I was fueling the bike at The Gap to ask about the bike. He struck me as a real Buell pro, and was riding an XB Lightning. He told me that he and the folks at his dealership keep an eye on BadWeb. I don't know his handle, but here's a shout out for Brad - and a Tennessee salute. Jack | ||

Jack- I PM'ed you about the dyno file. | ||

This thread is getting about as much avoidance as a turd in a swimming pool... No two dynos are the same, but searching for a fast one makes no sense to me. After all, we have already seen one result of 140+ on a new bike out of the crate. Any body believe that was accurate? What is important here, is the comparison of several bikes on the same dyno. Spike has offered to help me get the dyno results on the site. I had them scanned to pdf files, which were too large for me to upload. I think that the comparison run with the 1098 will be the most interesting and instructive. Thanks, Spike. Jack | ||

You'll get some comments once the run is posted Jack. I'm watching. Z | ||

Jack emailed the files to me this morning, so here they are: 1125R 6th gear:  1125R 4th and 6th gear runs, graphed over speed in MPH:  1125R compared to an XB12Ss and a VTEC VFR800:  The one everyone should be waiting for, the 1125R compared to the 1098:  | ||
| Zac4mac |
Wow! Very close on the Buell/Duc comparo. Now THAT'S interesting, especially the giant hole in the Duc's. Thanks guys Z | ||

The owner of that 1098 posted an overlay of his 2 dyno runs,which that is one of, at ducatispot.com He say's he took his bike to the dealer for service and they said his tps was not initialized and they got codes saying his cam timing was off. | ||
| Jpfive |
Mingo, I suspect that both of these bikes would have pulled 135HP on Cycle World's dyno. That's pretty strong for a bike with bad cam timing - I'm surprised it ran at all. Once again, my hat is off to Ducati. Wheeler had three 1098's on his dyno. Guess I should have asked to see all three, but only one was stock - so used that one. Ducatispot.com is an interesting site. I'll make a point to join it and run down these dyno charts, assuming it is the same guy. I blanked his name on the original, out of respect for his privacy, but I remember it. Thanks for the heads up. Jack | ||

OK, joined ducatispot, and found his thread. Nice site, BTW, and amazing the similarity of threads on rough running, stalling, lemon law, ECU problems, etc. I guess everybody likes to gripe...  There was a lot of comment in his thread on the Wheeler dyno results, including one owner that confirmed his findings, including the flat spot. He mentioned going back to Wheeler's in June (original run in April), but I can't find the post where he made it, or reference to an overlay. I know that his bike is no longer stock, with a custom map and aftermarket can. Hope this helps... Jack (edit) Wheeler's top dyno speed on the Ducati was 167.3 MPH (Message edited by jpfive on May 24, 2008) | ||

Thank you Zac for the one positive comment on the lines our bikes write on a dyno sheet. Sheeesh, guys, I was trying to generate a positive thread on a wonderful bike. I don't know what's happening here, but the negativity is getting a little bit oppressive. FWIW, my bike generated a _lot_ of interest during my trip. And, would you believe it, not one person mentioned the pods. But, maybe people were just being polite - there were no negative comments made to me. The handling of the bike was exceptional, and the power delivery was just about perfect for mountain riding. I took a new rear tire up, and got more wear on the shoulders than on the flats - a rare occurrence for this Florida boy. On the Dragon, I was able to run end to end in third gear. Ain't no way an inline four could do that. I did this to demonstrate to myself that it would do it - not to generate the fastest time through corners. Dropping to second in places was more comfortable, due to increased engine braking in downhill sections, and better response in uphill switchbacks. My rule on the Dragon is to wave bikes around that catch me. I made at least a dozen runs, and only had to extend the courtesy once - and that was nursing a low fuel light down to the Crossroads of Time. I am 61 years old, and have never ridden a track day. The bike earns respect in the wild, folks. It is easy to ride fast. What better way to describe a sport bike, eh? Jack | ||

No prob Jack, I continue to be very enthusiastic about my 1125. Rode to work yesterday, about 8 miles of highway and never got above 3rd gear. Hit triple digits a few times. Dusted a brand new Speed Triple a couple of weeks back. That was FUN. Z | ||

Very interesting and thanks for posting that JP. I'm continually surprising other bikers with the 1125R, especially my buddy with the busa who bought one cause he knew I had money down for such a long time. He has to keep the ECM in the "A" mode to keep me from leaving him on the straights. To tell you the truth, this is also surprising me even though I know the power to weight ratios are close. What a fantastic bike. One the street, I really only need first, second and sixth else I'll get into trouble. But I guess as you said JP, third is "comfortable" for some corners if your not racing. The difference in some of these Dyno's is also interesting. I know there are lot of variables but I wonder how much varies from bike to bike? Shouldn't be much should it? | ||

Hm. This bikes power is certainly made for the street. | ||

Bearly, I think the differences between stock bikes should be pretty small. Not so the differences between dynos. What is illustrative to me in the graphs is an absolutely beautiful power delivery for a sport bike. Heck, for any bike - I could not ask for better. I included My Lightning Long, and my VFR, for different purposes. I really like the way the torque curve extends from where the XB's ends. Seems to me this is what a lot of folks have been asking for - and pretty well delivered with this bike. In the case of the VFR, I wanted folks to see the curve of a bike which has received nearly endless accolades from the moto press over the years. Mine was probably the best sorted, and near perfect bike that I have ever owned. Even so, the VTEC notch at 6800 rpm was as abrupt as the graph shows it to be. Also, the 92+ HP is another indication that Wheeler's dyno reads a little bit low - as most magazine tests put the rear wheel output at closer to 100 for this bike. I don't want a perfect bike. I want a fun bike - and different works for me too. The VFR was near perfect in a lot of ways, but it bored me to tears. Imagine, I traded it for an XB....! What can I say about the 11...? Well, it does it all for me - proud to own it and love to be seen on it. Jack | ||

Hey JP looks like you made the Killboy front page: http://bp0.blogger.com/_LxZ4Mi3rR3Q/SDz_B7I314I/AA AAAAAAI7Y/PiyxV8NUQe8/s1600-h/img_7437.jpg | ||

Well, I'll be danged... Helps to ride a bike they don't see much I guess. Thanks for the catch. Jack | ||
| No_rice |
yes it does! he was trying to figure out when they started making them in orange, lol. i said they dont...   i didnt get the chance to stop and sey hi to wheeler while we were there in march. he really helped my friend and i out last time we were at the dragon. if he hadnt we wouldnt have been riding thats for sure. and Zee from Zeephoto was nice enough to turn around after she saw my friend break the chain(yes chain...) on his TL while we were meeting her and give him and the bike a lift to wheelers. | ||

What wire is easiest to use to get a tach signal so you can get the torque? I ran mine on a DynoJet tonight at a bike night. 129.85 hp. Guy didn't know exactly where to dig into it to get a tach wire. Said if I can find it to come back thursday and he'd run it again for free. Everyone was impressed with the numbers. They had been running modded HD's all night, getting 60-100 hp runs depending on bike. They figured mine would be around 110ish. Boy were they wrong! | ||

you tell them jack i have had all kinds of bikes that i thought were sport bikes but my 1125r is the real thing.my duc. cost too much to maintain and was very finicky.i let my son ride my bike ,he has a ninja 600 he twisted up some and almost went over backward .all hail the torque monster | ||
| Cutty72 |
Ok, ran it off the rear plug wires... 129.59 hp 74.35 ft/lb torque Not bad. all stock, solenoid unhooked and inner airbox removed. 2200 miles. |
