anyone do the 1/4 mile yet on the 1125R, or have some numbers to go by, like what it should be able to do in the 1/4. mike | ||
| Dalton_gang |
I crunched some numbers about a month ago and figured high 10`s with my fat ass on it. The formula I used is at the office but I will try to remember to post it Mon. or Tues. I`m also curious to know what it will run (actual not on paper) | ||

What does a bike with similar power numbers run? We should have some concrete numbers when the moto mags get their hands on the bikes. | ||

Hey Mike I hope you plan on taking that strap off of the Uly and putting it on the 1125 for some laps down NED in the spring! I would expect mid 10's with a strap and an experienced or natural drag racer and high tens to mid elevens for everyone else. PS you will need leather pants and a lanyard (cutoff) to run that beast!

Hey Scott, yes I am planning on being there this year, and hope to be a good season, my son has the uly now, but he is still learning on the blast I bought him for his 18th birthday, the uly is in the shop for the second time, broke the oil pump in early Oct, did not get it back to Dec, missed allot of good riding days, so Manchester HD Buell is on my shit list, they did not even fix it right, so they lost me as a customer, so when I got the 1125R at Big Moose Buell in Maine, they dropped it off and took the uly, the rear cylinder was leaking oil after a top end job, and had a few other problems. I was looking at those straps today, feels like the bike might do under ten, has allot of weight up front for a good launch, and the straps will improve on that to, hope to catch you up there, let me know when you are going. I am planning on going to penguin racing school in the spring, so I can do track days at loudon. this bike is awesome, and I have not gone over 7000 rpms or full throttle, and it feels very quick, got 300 miles on it, and will not open it up entill 1500 to 2000 miles when I change to syn oil, just did the second oil change last night and got it registerd the day it was under 10 degrees, the blast would not start, so I tried the 1125R and the lock was frozen, so I put my shop light on the blast, and it finally started, I also got the lock unfrozen, and the 1125 started no problem, but I took the blast because it was street legal and insured, I had to make to trips because the insurance agent put 07 instead of 08, I had heated gear but was getting brain freeze around my eyes. mike | ||

and yes I will need full leathers to do track days to. Mike | ||

Speaking of power to weight. From what I have heard from my friend about his new Hayabusa, the 1125R has the same power to weight ratio. I'll bet it will be quick. | ||

BMC says 440 lbs wet plus my 160# = 600 lbs. Buelliedan dyno'd Loretta at 126 HP to the road. 0.21HP/lb =156.6 Watts/pound ≈ 1HP/ 5lbs In contrast, my XB9R was around 420 lbs(580 total), but only 76 HP, as dyno'd at HC-HD when she was a year old. 0.13 HP/lb ≈ 1HP/8 lbs. Z | ||

If the HP numbers are accurate from Buell, then the bike will probably run around 10.3sec / 137mph in the quarter mile. As a reference, the first generation Aprilia Mille turned around 10.6 / 133 with less power and more weight, and with a measured top speed of 170-174 mph. The top speed of the 1125 will depend on aerodynamics and HP, so it's impossible to predict if it's going to be faster than the Apes or not. It's got the power, but maybe not the right shape for wind penetration. | ||

The next time you get bored, try plugging some numbers into this.  | ||
| Baggermike |
what about the force induction that it has, could that add hp at speed and the faster one goes the more hp it makes? I am unsure if this design will work this way, but am curios. Mike | ||

Mike you are correct about the function of the "ram air" effect. but how much can one gain at speed is still an unknown. someone will have to recreate this effect on a dyno to get real numbers. who is up for this project? | ||
| Diablo1 |
Take it to the track and find out. | ||
| Dalton_gang |
I forgot about the boost factor. Does anyone think that the "boost" from the ram air is going to be enough to measure in p.s.i. when the bike is at speed? If so then what do you think it would be at 60 mph, 90 mph, and 120 mph??? I would love to get a turbo and a wheelie bar! | ||

Diablo1 has it right, the Turnpike of Truth! | ||

I will be hitting N. E. D. when it opens up, it is winter were I live and I am not drag racer so do not know what I will be able to do on it, but would like to know how close I can come to a pro on the bike, that is why I posted this here, to see what a pro can do on this bike, then I will have something to go by and see if I can get even close to the same ET. Mike | ||

I think a few years ago a magazine ran a test that measured the air box pressure of ram air equipped sportbikes. If I remember correctly, there was a sportbike twin in there, but I dont remember what. Anyway, the best of the group only made a couple psi in the positive, and that was only at 150 plus mph. Most stayed at or near even air pressure. But, even air pressure is a big improvement over negative air pressure present in non-ram air bikes. The twins showed a lot of fluctuations in pressure, as each cylinder gulped a lungfull. My guess would be if its pressurized, it isnt much. | ||

see if I can get even close to the same ET When reading the magazines watch for "corrected e.t.". This mathematically corrects the e.t. for atmospheric conditions and is great for comparing performance between different bikes that were tested on different days or even different tracks. The problem is is is easier to launch a bike making less hp. So when a run is corrected from a hot humid day with a high density altitude the 60' time (short time) is also corrected - often beyond what the same rider could pull off if the weather was perfect! This makes a corrected e.t. difficult to match in the real world. Also, just going to the track once or twice, every now and again, isn't going to cut it - you need to make passes. Practice does not make perfect, it is almost impossible to lay down a perfect run on a bike (you can always find something on your time slip that could have been done better), but it does make for better e.t.'s.....  | ||

YA, magazines usually publish "corrected" et's and trap speed, and usually have a dedicated drag race guy (who is usually real small, to boot) to drag test the bikes. Like Scott said, makes it real hard if near impossible to duplicate their numbers in the real world. | ||
| Bigblock |
But i'd sure like to know what my bike can do with my fat ass on it, hoping sears point opens early this year. | ||
| Scott_in_nh |
Mike and I race at a sea level track that sometimes has air that is better than standard! Also, while I'm no Rickey Gadson, I'm small enough at 165 lbs. and have decent enough bike control to have come close, matched or bettered what the magazines have run on several bikes ![: ]](http://www.badweatherbikers.com/buell/clipart/proud.gif) but the weather HAS to be right! Regardless of where your track is, I highly recommend taking runs as a safer, fun and inexpensive way to enjoy your bikes performance, improve your riding skills and meet some great people. | ||

Buell 1125R runs quarter mile in 10s, 141 MPH. |
