or vice versa. I look forward to reading a side by side test, XB9 vs XB12. Or running into a XB12 on the street. This month several of the british Mags review the 12s. (superbike,performance bike,bike)they all state the 9s rev quicker and have the 12s beat in top speed numbers. of course the 12s crank out more HP and torque. My 9 revs pretty quick, But not super quick. I can't see buying a bike that revs up even slower. Add to that the Gaudy gold wheels and screen, the jumbled mixed metals, alloys and magnesium tones, the higher price, slower reving, slower top speed, I am glad to own the XB9...Am I missing something? I bet 2 egual riders on a race track, one on the 9 one on the 12, it's anyones race..Thoughts ?

I can't imagine what the magazines are talking about. I love my XB9R, but an XB12 will wax it in a race, that's for sure! Have you ridden one?

The XB9R is faster than the XB12. Just ask Brian down at Tilley's HD about it.

Seems strange that with more HP and torque and about the same weight (neglibible difference), that the 12 would be slower than the 9, at least in a straight line.

After test riding a new XB12S, admittedly not broken in yet, I was impressed with the raw acceleration of the beast.

Back on my XB9S I was impressed with the smoothness, with 3,300 miles, of the smaller motor.

But put me on the 12 and Erik Buell on my 9 and put us on a road course and he would win most every time.

Imonabuss..what are you basing your facts on?
"wax it"...no way !!!

Bigger engine, bigger torque and HP, bigger Price tag. It should "Wax it"..But it doesn't.

Eric Buell says the 9R is for the youth and the 12R is for the more mature rider..I'm not sure what he means by that.
He compares the 9R to a chevy small block and the 12R to a chevy big block...there are to many different small and large blocks to pinpoint what he means by this statement also..283,327,350 400 small..396,427,454 big..
He was also ask why the old air-cooled engine is still used..He stated he wanted the bike to be different than the Jap bikes. He pointed out that even if he wanted to compete, buell could not do them as good as the Japs. I love my Buell, but to point out it's done different because it can't be done as well, is an odd statement I think.

Thats sure as hell not what he told us at the dinner we had last week. Where did you supposedly hear that at?

superbike magazine, sept 2003...article called "weather report" ..
chatting to erik buell later in the day,I began to see the logic behind his bikes. There's no point in Buell trying to copy what the japanese firms do-the result wouldn't be as good.

re-reading it, maybe the bike tester/writer had that thought...even though I think it's true.

what did Buell say at your dinner party?

I now own a XB12S and have ridden both 9's and this thing will pull away from the 9's with out a doubt.And as far as competeing with the Jap's they are in Europe.Just ask Matt Purdy owner of Trojan motor product's there about to win the title running against 750 inline's and the like.It's just that the AMA has total different structure here,and it suck's.

The bikes have a different primary ratio and the same tranny ratios and final drive ratios....so it's possible the 9 could out pace the twelve if the twelve revs slower.... I have ridden both but didn't wind the 12 up so I am only guessing. there's a lot more punch in the twelve......

The mags test riders over here ware complaining that the 12 was revy and that the hit the limiter to soon and to often,
So I really don’t think a 9 will beat a 12 because it “will be more revy “

But at the bottom line it al comes down on rider capability

Just my $ 0,02
Gr,m

the 12 does not rev up as quick as the 9...and the 12 hits the rev limiter before the 9 does.

How do you figure the 9 will rev up quicker?

It doesn't seem like it should ... the 12 has a 20% advantage in horsepower and torque over most of the operating range. The 9 is only geared about 12% deeper.

Bubba from Tilley's has it spot on. If you live where all the roads are like Deals Gap, real tight, then yes the 9 is perfect. I have taken the 9 down a real curvey road and was able to keep it between 90 an 110 without blippin the brakes once. NOW I can't say much for the 12 seeing as I didn't take it down the same road yet, but I don't doubt for one second that it can't perform the same without that little bit of extra umph to cause a ass puckering rear tire slide you wont soon forget.
The Real test will be to get a rider out on the track and do laps with the 9 an 12 and see what happens till then keep on bench racein cause these comments are hilarious LOL

the 9s rev quicker due to their shorter stroke.

I think you have that backwards. More stroke = more mechanical advantage on the crank. So for a given combustion pressure, more stroke = more torque. And for a given load, more torque = quicker acceleration (f=ma). In fact, that's how a Dynojet dynamometer works, it derives horsepower and torque from measuring how fast a drum of a known mass spins up. Spinning up faster to a given speed shows up as more torque and horsepower.

The only caveat is that the 9 is geared deeper. This gives the engine more mechanical advantage, effectively reducing the load it sees in any given gear. However, the 12's torque advantage is greater than the 9's gearing advantage, that was my point. It ought to rev up quicker anyway.

>>>>the 9s rev quicker due to their shorter stroke.

It can be allowed to rev higher cause of a shorter stroke IE 7800 red line but that doesn't mean that it will rev faster. Aaron does know a little about this stuff ;)

Reving quicker vs. higher red-line. That's the important destinction that needs to be made.

I'm not a Mechanic, nor pretend to be one. I guess my bottom line is, I can't wait to see the 9 vs 12 on a track, with equal riders. Do I wish I had the 12 engine?, yes most likely. do I like the look of the new 12s?...Not one bit. Am I happy with My bike? yes very Much.

"The XB12's taller primary ratio is effectively offset by the big motor's reduced redline, resulting in a rev-limited top-speed approaching 140 mph on the dial." -Don Canet (Cycle World, Sept. 2003)

I don't know about yours, but my XB9 falls about 15 mph shy of that mark when wound all the way out in 5th gear.

The UK bikes are geared differently to the US bikes, more speed less accelleration, I think my 9 could pull to an indicated 140. Ill find out...

I had Mine up to 130mph, and still pulling. Who know how accurate the gauge is. I'm fairly light and small. 5'8-140...tucking in behind the double bubble puts you in a different world. No wind, hardly any sound, just the exhaust note sounding a long way away.

Misato..I wish I had the cash to do engine upgrades.

anybody know if you can buy a whole XB12 engine from the dealer, and if so how much ?
Just curious...

like to know what the cost differance in engines are also.

Wonder if the XB12 engine could be retrofitted into a tube framer...
