has anyone thought of swapping an 1125r motor into the firebolt? it obviously would be ALOT of work, but how much bigger in size and weight is the 1125r motor, and do the motor mounts happen to be in the same spot? its just a thought with the fact that it is a watercooler motor instead of just a oil cooled motor, and the extra gear seems like it could be in use. and for all of those that think you cannot make a firebolt fast, i have a xb9 with 1200 big bore, includeds axtell cylinders, some head work was done, new cam, xb12 primary drive, and full streetfighter exhaust, and the chain conversion, the bike i believe almost may touch 200 mph, but my speedo does obviously not go that far and i have tapped it plenty of times, and for those that say you cannot build a fire bolt to beat gsxr's, i have proven them wrong, my friend has a 2007 gsxr 750 with power commander, full exhaust, and custom intake and i take him off the line all the way to the top. if anyone has an idea about the 1125r motor. let me know....thanks! | ||

Let us know how you make out. | ||

1.) I think someone is already doing this. Could've sworn i saw pictures.... 2.) It may be water cooled, but if you'll check on the 1125R forums here, they're having some REALLY bad heat issues. Those things are quite literally blistering people's legs. And it seems that the 1125R is suffering from the same fuel injection map issues that the '08 XBs are having. Just FYI. ~SM | ||

You must have a hyperspace button on the XB or your friend with the zuke is just playing with ya. | ||

good to know there goes the idea of swappin the motor. you would think that he is playing with me...but if you know how to build a motor correctly... you can make any xb keep up with most gsxrs, well of course except for the busa and mayb the 1000's but believe me my friend is no inexperiance rider and either am i. its all about knowing how to make things work, im also pretty sure that he would not lie to me when saying dman, you made that bike fast as hell. wen i get the chance to get a few pictures or take a video of me beating on his gsxr. i will post. also i love the fact that the firebolts have so much flick, in and out of every corner and in between cars, this bike is just all around amazing. | ||

There are a few drawbacks for such a project. The XB wheel base is too short and the steering geometry is not stable enough for that much horsepower (racers lengthen it). Also, the frame is designed for a low power engine and I believe is still is heavier than the 1125 frame. XB brakes are way inferior to the 1125, and you'll need the brakes with that much more power. I don't see the benefit, I'd just save up for the 1125. | ||

PS: I am not opposed to the general concept of upgrading to a stronger engine. What is more American than shoving a huge engine into a small chassis? I have a 1998 GSXR 750 that I'm thinking of eventually putting a 20XX 1000cc engine into. That is a case of a frame, geometry and brakes that can handle the upgrade in power, at least to a greater degree than an XB can. | ||

i have a xb9 with 1200 big bore, includeds axtell cylinders, some head work was done, new cam, xb12 primary drive, and full streetfighter exhaust, and the chain conversion How do you get it to fuel properly? | ||

What sprockets are you running. I don't think it would be capable of 200mph and also beat a gsxr600 (much less a 750) off the line. Would have to be some pretty tall gearing to see 200mph. | ||
| Spatten1 |
Sure it's possible. You just need one of those top fuel Buell engines....Made by S&S. | ||

I can probably gar-un-teee that you don't have enough motor to get to 200mph on your XB. Guys spend a LOT of time and money building these Buell motors to do exactly that, and I seriously doubt those bike's abilities in being remotely streetable. Anyways, an 1125R is so similar in general design to a Firebolt (aside from the drivetrain) that you may as well just buy an 1125R. | ||

Anyone heard anything about BMC doing all the work for us and putting the 1125 motor in an XB chassis? PLEASE!!!! When are the new models due? | ||
| New12r |
The 1125 is more work than it would be worth in an XB chassis. Motor mounts are NO WHERE NEAR THE SAME. You will give a welder 1k just to maybe get the motor to bolt in. I spent a bunch of time looking at the two and you might as well buy the 1125R. It handles better, has better fairing/wind protection and feels lighter in the flick than a firebolt(and I LOVED my firebolt). And really, are you claiming 200mph on a bike that gets a little squirelly at 140mph?? Be realistic please. | ||
| Jaimec |
Maybe his friend's GSXR is only running on two or three cylinders... | ||

Huh, my 12R doesn't get "squirrelly" at the top -- but maybe you are thinking of the S.  I'll be sticking with my XB -- just love riding it, and I will be sticking with my XB's engine due to the fact that I know plenty of people who can work on them and do fun/cool stuff once my warranty is out (or maybe before...shhhhhhh, don't tell). I like having an engine and a bike that I can work on and will be continue to be a classic engine design for another 25-50 years. I have a thing for classics. Picking up a tuber is on my list of things to do as well. (Message edited by retrittion on July 02, 2008) | ||

Your love for Buell is surely encouraged, but making claims that far out with no proof is just crazy. First, do you have a dyno sheet to show the power from this 200 mph bike? There is no way you could possibly get fuel in to that engine correctly without putting it on a dyno, so let's see it. You'll need well over 150 hp to achieve that, and some really tall gears. A friend of mine pushed his XB out to the 1370 or 1450 kit, (I can't remember exactly what it was) but you are talking case cover modifications, cams, pistons, cylinders, balancing, polishing and anything else you can think of and it put out about 130 hp. Then of course he had to wrench on it more than ride it because it always broke down. Many have done the 1200 conversion, and you're not going to double your hp with it.... | ||

Huh, my 12R doesn't get "squirrelly" at the top -- but maybe you are thinking of the S I have had an R to the redline in 5th and it was not as stable as I would have liked. I was not uncomfortable,but the rice bikes I have rode and especially the 1125 were less effected by the wind and drag. | ||

WTF is the point? Why not put an 1125R engine in a fricking 1125R chassis? I mean really... What would be the benefit to putting one in a Firebolt chassis? I wouldn't mind building an 1125 Chopper though  . Totally old school with white walls . No... I have no idea where to put the radiators. | ||

Hals built the 1st 1200 conversion ever in an XB. It's built professionally by some of, if not the best Buell race mechanics in the biz. That kicks out 100HP at the wheel. Which is admirable. Will it beat a Gixxer 750 off the line, yup. Will it do 200 MPH, not even close. Will it do 170MPH? Nope. Sorry... You don't even have enough gear to go 200MPH, much less motor. Sorry. An 1125R, kicking out 140 HP at the wheel(The race bikes), wont do 200 MPH. They aren't even hitting 200MPH at Daytona. This is a bike with MORE horsepower, far better aerodynamics, and more gear than an XB. Speculation is fun. But you really need to back a claim like that with solid data. | ||

Wow this thread is great! Based in hearsay and extremely deep bullshit. The ZX-14 and Busa both have tons of horsepower and barely surpass the double TON. (in stock form w/ restrictors removed) First off, brand new 1125r with a factory warranty - $12,000. Building a XBR to mate with a Rotax, air-cooled motor - $10,000 (if you don't have to buy the XB) I put in time at a shop that specializes in basket-case builds. I can tell you stories of large amounts of money and bikes that are never ridden to their built potential. If you have the means and drive . . build it. But I find it to be a waste of your money and the destruction of a good bike. (if you did it right) Why would you build a bike that Buell already made and just started selling? Kind of pointless. Ridrnkink18 - You want a real build? I can currently get my hands on a '04 RC211V 'Biaggi' motor. Why put a motor that has already been put into an XB. You want extreme, here ya go! If you know what it is and understand what it will cost . . . we can talk. | ||
| Gschuette |
So you want a heavier chassis that holds less fuel? And forgo the perfect engine mounting points for what? A two inch smaller wheelbase? Hell the two frames almost look identical from the outside. Why? Really please tell us why? | ||
| Ridrnkink18 |
to answer all your questions i did not say I DID 200mph with the chain conversion i can't remember off top of my head the amount of teeth on front sprocket, but i run a 38 tooth rear sprocket, i also had my ecm tuned to deliver the fuel to its proper amount. and for all who say it will not beat a gsxr 600, i smoked my friend on his 600 last night down route 22 all the way to top end left him atleast a 1/4 if not a half mile behind. unless you were there with me you dont know how the bike runs, mayb i just happen to know how to build a bike that runs fast, the speedo goes up to 160 on my bike, and i have tapped the speedo more than once and still have plenty of 5th to go. so the thought of it going 200 is not out of the question. and yes i beat my friend on his gsxr 750 for the last time, its an 07 which is no dog whatsoever, your trying to say you can't build an xb to go that fast, mayb you are doing something wrong. mayb i got lucky, or mayb im just good at what i do. btw i had my sprockets custom made, and the xb12 primary adds about 10 mph off the start, wen i was at stock xb9 motor, my one buddy(who is a cop) clocked me doing 153 with a 43 tooth sprcket and no xb12 primary. and olinx i never said double horsepower, and its all about taking care of the bike and building everything to work together. anyone, come bring your gsxr 600 to 750 and come play with some american muscle, show you all who runs the streets around here | ||
| Steve_mackay |
mayb i just happen to know how to build a bike that runs fast And many of us have been around Buell race teams that have raced the 600s long enough to know how they do. Without some major massaging on the internals(headwork, cams, *PROFESSIONAL* dyno-tuning). You're not going to beat 600s off the line *AND* at top speed. modern 600s are pushing 110-115 to the rear wheel. Many of the ASRA thunderbike motors push out that HP. Those are 1450CC, 13:1 compression, total loss ignition system, no starter, no stator to reduce internal friction losses. Etc... These are $8K worth of upgrades. If you think you can seriously produce that type of HP to beat 600s, I suggest you try and market yourself, since you're doing what all the professional engine builders can't do. | ||

BTW when you change your final gearing ratio your speedo readout means less than nothing. Even from the factory 10% error is acceptable above 100mph Also, what is your rev limiter set at? the stock speedo sensor "should" be showing you around 145 at red line no matter what else you have done. Unless your bike revs to over 10k it just isn't happening. This is because ***warning scientific content*** the stock final drive at approximately 3:1 gear ratio will put you at 145 at redline on a 9. Even with different gear ratios the sensor on the output shaft can only spin so fast. Also, what compression ratio are you running? my XB (the one Steve mentioned earlier) which was built by Terry G. of Hal's is running 11.43:1 compression is barely streetable on pump gas. IF you want to see my dyno sheet just check the show us your power thread in the Knowledge Vault. It's time to put up some real world number from a reliable source to back up your claims. No one is that good or that lucky. You should talk to some of the land speed record guys like firemanjim about just how hard it is to hit that magical 200mph on a Buell | ||

I will only except a 1/4 mile time slip or a rear wheel Dyno Sheet, other then that its just bench racing. | ||
