Actually if he has a xb9 he stock top speed would be like what, 135-140? If you look at his other posts he said he was putting on a primary gear from a xb12. 11% is like 15 mph. So thats 155mph and he also did the chain conversion he could theoretically have a top speed of 190+ mph depending on his gearing. My friends F4i top out at 80mph with their gearing, BUT I seriously doubt he has the power to get there though. I'd be interested to see if anyone can come up with an equation of how much horsepower would be needed to get a firebolt to that speed while factoring in drag.

It will be done (the calculations) but I'd like to hear his answers first as to his rear tire and if he has changed his redline via ECMspy, Kimball software, etc. and what configuration of bodywork/windscreen etc he is running. The formulas exist and are used by those who seriously pursue engineering performance. There is no mystery in how to achieve the real world performance being claimed, BUT achieving both high performance drag racing acceleration AND major top end speed is counter-indicated. Either is Do-able with the right engine build, and I mean MUCH more than a big bore top end and gear swap but you need short gears if you want to out pull the gsxr 600/750 on the bottom and tall ones to hit 200. I don't believe he has a bicycle type derailure to change his final drive while he is in motion. Aerodynamic drag is a more and more serious factor as speeds increase trying to hit 200....err 192mph. | ||

" a bicycle type derailure to change his final drive while he is in motion." Cool, now there's a concept waiting to happen. | ||

Perhaps someone would be willing to test the equations for me. It seems a good idea to test the equations on something that is known before getting to the unknown. By playing with primary gearing we think we have already reached to within 4 mph of a speed target that we were told we not get near without an engine rebuild, and we have fitted a new pulley that has the potential to go closer to the target. We don't know if we can rev limit with this one yet. My friend's 2007 XB12R with a Micron, open airbox and an aggressive tune has gone to the rev limiter with a 41 tooth crank pulley (instead of the stock 38). It dyno'd at 106 RWHP (which is probably optimistic). I have a 2007 XB12R with a similar setup fitted with a 42 tooth crank pulley . How fast can I go, please? | ||

I removed the Harley-Davidson tank decals from my X1 this morning and went for a putt this afternoon and gained 10 mph top end ..............no kidding. | ||

Wanted to test my new (to me) bike's highway capabilities this afternoon. Got my x9 firebolt to cruise at 110 - 120 easy, ran for awhile at 130, topped at 140 and relaxed. I don't usually drive my car at 130. At 140, it didn't seem to be straining but over 130 the wind was brutal. Made the mistake of looking back and had to fight to get the helmet forward again. I wouldn't push over 150, if you're caught here you lose bike and license right now. The test went well, gotta love Highway 402. (Message edited by iamarchangel on July 07, 2008) | ||

hahahaha dude this post best ive seen yet...im with lanret....with the right gearing and the primary...it will touch 200...and the right amount of power to get there..unfortunately i blew an oil line riding this weekend..  i was once again riding with my friend on his 750...and hes no bag...get on line next to him...im sure he would take any of u not on a busa...and my goal is to beat a busa one of these fine sweet days!!! going to be really hard i know...im actually on the verge of doing a turbo firebolt since noone has the balls to make a kit for it. i have to do it all my self...once thats done...we will see whos bike does 200!!! thanks for all the posts did not want to start a huge argument but every guy has to carry his own nuts. | ||
| Lanretsr |
You seem to be pretty contradictory. I thought you original post was that your bike can do 190mph? And since it was already stated that a busa only does 192 your pretty much there. I did state that with the right gearing you should be able to do 190 if you had enough power but I'm confused on how you can beat your friend 750 off the line and stay ahead of him all the way up to that speed. What kind of motor work do you have done? You didn't answer anyone questions and jumped on the wagon with me since I was the only one that some what backed you up. Post some videos of the bike or what you have done to it or better yet go on a ride with one of us. Otherwise its just all talk like most things are. | ||

HID kit...another 15 horsepower | ||
| Jaimec |
I find that you can go faster if you don't fix your headlight reflectors. You have less light pushing the bike backwards as you're trying to move forwards...  | ||
| Mikexlr650 |
this is easy, he's in new jersey, hammer is here in new york with a basically stock gsxr600. lets set up a ride and we can answer these questions quite easily. | ||
| Hammer71 |
It is stock.... Lets run em. | ||
| Mikexlr650 |
isn't it great when you can voluntier your friend for a stupid and dangerous task and not only does he respond with a "he'll-ya seems like a cool idea" but everyone agrees and wishes they could be a part of it. gotta love this place! back to real life now... | ||
| Ridrnkink18 |
im not contradicting myself at all...my bike may reach 190 but i never said i would take a busa off the line...which is what i want to do..run a busa from the start...and as i stated i need to redo all my oil lines..the fitting from the oil cooler on the end of the steel braided section just blew off the other day got slippery as hell and oil was all over the place it was a nightmare i thought i blew the bike up...you want to know what i put on the bike...go look at this site and you will see the 1200 big bore with the axtell cylinders...i bought a cam for top end rather than all around power because the bike is a monster on bottom end anyways....and because of all your attitudes im not going to give you my secrets on what i did to give it the extra push it needed..if everyone was not such a dick about this you could be almost doing 200 as well!!!!! http://www.revperf.com/XL/xlPerformxb9.html...they also sell basically the similar kit on this site...http://www.nrhsperformance.com/ekitsportster.shtml ...if i were you i would look into these kits...it makes a whole different kind of bike...it is very reliable as long as your not beating the rev limiter...and tuning and tuning and tuning...do whatever you can to make power to weight...you will have a screamin xb...also i did not change my *belt* pulleys...i have a chain conversion with custom sprockets which i actually have my uncle make...he is a machinest btw....go get the chain conversion and put a 37 tooth on the back...make more power...you will see how fast it goes although im guessing what i do...but friends bike tops @ 186 and i was justtttttttt able to pull on him wen he had nothin left...so i did about one ninety...and in mph not kmh...unless his bike lies about how fast he goes which i doubt. and i notice someone made a comment about not liking people who rip the streets...why buy a bike that will go fast if your not going to actually ride it to what it was built for...people who follow the man and listen to his laws are the people i love to smoke by. | ||
| Ridrnkink18 |
and i wouldnt even give a gsxr 600 the chance to try and chase me...it would just be an embarrassing moment for all of you who have to ride a 600 because they cant handle the extra power...any 600 feels like my crf 50 wen i get on it | ||
| Iamarchangel |
Just for the record, neither link works. Any other info? | ||
| Xb9rnutt |
Take out the they and the if at the end of the links. | ||
| Mikexlr650 |
the 600 is what we have access to, it's a good baseline and an opportunity for you to shut people down. setting up a ride is easy as we are quite close by, no animosity, lets just see what they'll do! hammer is a good no bullshit guy, if your bike smokes him he'll be on here stating that your bike is no bs! he's also a skilled rider, many on this board have ridden with him and will respect his opinion. too easy not to do this. | ||
| Hammer71 |
Look I dont care if it goes 300 MPH I'll run it just to see it go like a bat out of hell. It may very well do what you say but without 100% proof no one here will give you credit. Short ride to NY ( Bear Mtn area) nice long strech for a drag race and if ya win.. great, I will however kill ya on the twisties. The only factor I see with your friends MPH deal is speedometer error, is the 6 to 10 percent factored in? | ||
| Mikexlr650 |
600 not enough, ok we have a zx10, and a 14 available as well. you have to pop the 600 first! i would love for you to be able to do this, we all would. this is a buell site! giving you every opportunity here to make yourself look good. | ||

So....the size of the output shaft sprocket, the size/brand of your rear tire, and what bodywork you are running are SECRET (shhhhh don't tell anyone!)AND you happened to blow your oil line this weekend requiring what is obviously a huge, time consuming repair making it impossible for you to back up the claims. Changing any oil line on the XB, or even all of them, takes minutes. It's not rocket science and I'd expect a master engine builder to be able to handle this. Then again, I'd expect a master engine builder to not make excuses for why his bike can't make the numbers that have been claimed. Then again, every master builder I know does actual scientific testing of every motor they build and can produce hard numbers and dyno sheets for every engine they have built in the past 10+ years with dyno time being so widely available and as cheap (relatively speaking) as dyno time has become.} | ||

Just for the record, I've seen this kid's bike in person and it's the read deal. It's wonderous what you can do with a little know-how, a couple muffler clamps and a JATO bottle. | ||
| Spatten1 |
I've ridden an XB9 with the 1200 kit. It has great torque and is really fun to ride, but ain't gonna beat a 750 GSXR to save your life, forget about a literbike. | ||
| Spatten1 |
Oh, by the way, I do own a 1998 GSXR 750 and a 2003 XB9, so I am not speaking theoretically here. | ||
| Vtbueller |
I've owned 3 Suzuki sport bikes and all of their speedometers are very optimistic. They are off by at least 10% as noted before. That means that a nice XB12R with some engine work ( pistons etc...) and possibly a bottle might do 170mph. With a chain kit the wheelbase can be longer and handle it better. I forget the rule of thumb, but each 10mph will cost much more $$$$ and take more work than the previous 10 and take more work. You will also introduce many other issues as you add speed and power. Please do yourself a favor and don't use another bike's speedometer as your gage for progress. It's a very bad way to measure your hard work. | ||

haha ok guys when i honestly have the chance to get out there i will...and hammer...the twisties is where the buell is made to beat on the jap bikes...dont be too sure about that...i have been riding street bikes since i was ten...everyone has their skills im not doubting you at all...and i have the same body work as always..except the little fairing underneath which i think made it not look as good...the day will come i promise...im twenty years old paying for a mortgage...money and time spent out of state is hard plus the hobbies i have like spending every last penny on my buell!! i will be back and forth on the site when i have the time to get up there..because i work 7 days a week...i will get up there...plus i love long rides and where is your place in new york? is it upstate? cause i really enjoy upstate only been there like 2 times wouldnt mind going back to put some kids back in their seats and ya know...teach you some lessons...i did put a picture of the bike when i FIRST had it in the driveway as mine...its a completely different bike now...there is not one thing on the bike that is not black now...like to not be seen at night | ||
| Ridrnkink18 |
and to answer back to vt...did you do a chain conversion on the 12? because when i first had the chain converson i put a 39 rear tooth and at redline in 5th i was well passed the amount the speedo read...which as you all should know on an xb9 is 160...and for the speedo? has anyone thought of puttin on electro speedos? i mean they cant be that unaccurate i found a really good site in uk. for some reason they are crazy for buells... http://www.trojan-horse.co.uk check it out they have the best products for buells i have been able to find including a bearing kit for the front end that gets rid of the hopp wen takin fast corners...i cant wait to get that | ||
| Ridrnkink18 |
and i must say...when the bike was stock and i had the chain conversion it took me a real real long time to get to that speed...thats when i decided to do big motor work...plus when i rode with my buddy on his 750..he could pull on me like i was on a gsxr 600.... | ||
| New12r |
and hammer...the twisties is where the buell is made to beat on the jap bikes...dont be too sure about that. Good luck with beating Hammer....You are only 20 and have a lot to learn. And, Your bike with stock gearing is limited to 140mph. PERIOD. The speedo IS electronic and will read about 154 at the redline(that is 140mph in real life). So even if you changed the gears you still have not shown me ANY real proof that you have gone more than 140mph. Using a factory speedo to gauge speed is the most inaccurate way. You might as well use your foot to measure distance in feet. I appreciate your enthusiasm but your claims are wayy out there and with NO proof no one but fools will believe you. |
