So what Froggy, you got 53mpg once? I'll chalk that up to a fluke or error. Compared to the xb9, my bike gets bad gas mileage. Why try to make it look like something it's not? I should say the maintenance on the xb is easier, not necessarily less. Next you will tell me that turning the motor to change plugs and adjusting valves is easy. I can honestly say that changing primary oil and adjusting the chain is easy. | ||
| Froggy |
Ain't an error, I got 75+mpg on my XB12 on that same route. I can still pull high 40's easily, even on winter blends of fuel containing Ethanol. I have already figured out how to adjust the valves and change the plugs, it isn't hard, I already have the tools, but too date, nearly 60k miles on XB's, I am yet to get the primary chain adjustment correct. Not to mention how I never personally changed the plugs on a XB because of the risk of buggering up the threads. | ||

I have a XB12s with 23k and a 1125r with 3000.Glad I bought the XB first. Other wise I wouldn't have bought one and that would have been a shame. Glad I have both.Other than speed I do more crazy stuff on the XB than 1125. Slow speed torque wheelies around tight corners, fast thru traffic because I'm setting up and can look around easier.Short wheel base for easy stoppies. But if you got room to zoom the 1125 is the way to go. | ||

yep to clarify my XB12R and the 1125R had the same tyres but the XB had really trick suspension whilst the 1125R has standard suspension at the moment, agreed as well that I am approaching corners faster on the 1125R and also that the power pulses of the XB allow more unrestrained use of the throttle when exiting a corner. All in all the 1125R is a faster bike, no doubt about that but the XB is more relaxing to ride with the low down torque which makes gear changing an option rather than essential | ||

As an all around do everything bike I like my XB12 better . Although my does CR runs great . | ||
| Moosestang |
Froggy is the only person I've ever seen claim 75mpg on a xb12. No offense Froggy, but I think your math sucks. | ||
| Blackflash |
I agree with moosestang on those numbers froggy.I rode all highway to deals gap /smokey mountains from the lake in ohio in spring with the R stock flash and seen 46 mpg and that was at 65mph no major load .I was trying superhard to see what I'd get.And as far as my xb 52 mpg was the most I saw trying my hardest.Rotating the engine takes some time as well.My valves were right in spec and others I know were the same.On honda cars they say check your valves at 20k .My dad did they were fine then at 40 they were fine at 80k he finally had them adjusted.Just a procedure to keep you from breaking a valve tip or rocker arm.One guy stated to me that after 40k hes now just starting to hear his ticking more and will have them checked.No fudged numbers here!!Usually as the valve seats in to the valve seat the tolerance gets tighter .Then you have to take in consideration of the valve shims wearing in as well.If the metals are matched properly wear should wear in evenly and stay within tolerances.Just my 2 cents. | ||

"Has anyone actually weighed their bikes? " Sportrider magazine has.... http://www.sportrider.com/weights_measurements/146 _motorcycle_weights_measurements/buell.html Taking into account the fuel capacity, the XB12 and the 1125R are the same weight. Dirty_John, Have you noticed a difference in the braking performance between the XB and the 1125R? I assume you had both with ZTL2, right ? What tires you had on the bikes ?? | ||
| Blackflash |
If you are truly getting those numbers froggy then you need to take your bike in and see why its so lean.Pull a plug as well.You have to be running dangerously lean.A r on the highway should see better mpg than a cr.The steeper gearing will keep the rpms lower as well.Once i go over 65 on the r the milage drops.So with 8% lower gearing on the cr you should be dropping at 60mph.Your sweet spot is 60 or 58 mph.Mine is 62-65mph indicated on the speedo.Just my 2 Cents | ||

440 wet on a digital scale at track.pretty full on the tank with tools and passenger pegs. | ||

I ride my CR like I stole it and I get about 32mpg. Ya know what...I could care less. With 5.5 gallons of fuel on board, I am filling up at about 140 to 150 miles. Now, on the track....it will suck gas like crazy! I mean it's insane how much fuel the thing will suck down. I'm surprised Eslick didn't have to pit during the DSB races. | ||
| Froggy |
If it was the math, the website is screwing it up, as I am inputing the tripometer reading, and amount of gallons pumped. If it was the math, I wouldn't be able to go 230 miles (240 on XB) and then have the light just come on. That fillup was 232.8 miles on the tripometer, it took 4.41 gallons to fill, and had 4227 miles on the odometer. Do the math, its 52.78 mpg. I keep detailed logs of every fillup, including where I filled up, octane rating, and Ethanol content. http://ecomodder.com/forum/em-fuel-log.php?vehicle id=2963 For the record, my 08 R gets much worse fuel economy, if it doesn't pickup over the next 1k miles or so, I will be bringing it back to the dealer. | ||

75+ mpg on a 1200 cc bike is impossible unless you're going downhill the entire way. They only time in my life I got 75 mpg on a vehicle was on a 150 cc scooter I rented.. | ||

Bottom line is at 65mph, both bikes need to put down the same amount of energy to the rear wheel regardless of how fast the engine is turning. I feel like there were a number of XB guys that were getting better highway mileage by running in 4th instead of 5th gear. | ||
| Homer007 |
It's not linear but it is dependent on engine speed. | ||

I would never question Froggy's math. I've met him...I'm sure it's accurate. His fuel mileage is akin to those who say they are getting 10,000 miles out of a tire. Both are mysteries to me. I get 32mpg and 2000 miles out of a rear tire. One thing for sure...I'm not going to buy a high performance motorcycle and see how long I can make a tire last or how much fuel economy I can get out of it. I'm going to thrash it to within an inch of it's life and ride it like a hooligan on crack while I grin maniacally. I have a 125cc scooter with tires as hard as bricks and it gets 85mpg at WOT. It's like sleeping with an ugly woman. It's a hell of a lot of fun, you just don't want anyone to see you doing it. (Message edited by chadhargis on December 10, 2009) | ||

At this point, I never it put it past anyone to get "unheard of" mileage numbers. It's happened too often around here. Take a bike that gets 21 MPG at the track in Texas. Now, move it to the high mountains, where power goes down, but MPG goes up! Fill the tires up to 42PSI cold. Ride with economy in mind. Mostly do slab. Do it in cold air, with nice cold gas, on cold roads. That and a few other things and before you know it, you are averaging in the mid 40s! Same rider might get 6k out of a rear tire, too! Lord knows we have seen it happen around here a few times. | ||
| Xl1200r |
You'd want hot air, not cold. I used to get 65-66 mpg on my XB12 regularly. 2,000 miles out of a street tire that doesn't spend it's life on a track is a mystery to me. | ||
| Milleniumx1 |
I'm all about the 1125 bikes, but I do really love the looks of the XB's. Having come off of two decades of Harleys, plus owning my '00 X1, I still have a soft spot for the original twin. But owning the '25 is making that a nice, but yet distant memory. These bikes are just insane ... At least to me. Mike | ||
| Chadhargis |
2000 miles on the track would be insane. I have a rear Pilot Race that has MAYBE 180 track miles on it and it's pretty well shagged. In the immortal words of Ed Bargy...."If you ain't slidin' you ain't ridin'". | ||
| Blackflash |
You'd want hot air, not cold. maybe, Depends on how the Ecu is setup.Some programmers use more fuel to cool the bike down some use ignition retard?It might be worse? | ||
| Xl1200r |
And some programmers figure the radiators will cool the bike just fine and lessen the fuel going in since air is thinner when it's hot. | ||

I aint about the mpg +1 to Chad but I have ridden with Froggy he rides em as well so I aint beatin a fella up for seeing what ya can get out of it when its your commuter I think its good to worry a little about that stuff. I however can not use a bike as a commuter so I just gotta opt for the Thrash option and exit stage right | ||

About wet weight, I wonder what bike Sportrider Magazine weighed to get 474 pounds? Blackflash has an actual measurement of 440 wet, and in their review Motorcycle USA weighed their 2009 1125R at 434 wet. If you haven't seen that review from earlier this year, check it out, it totally spanks the ZX-6R that convincingly won their 2009 600 Supersport shootout: http://www.motorcycle-usa.com/9/3317/Motorcycle-Article/2009-Daytona-SportBike-Comparison.aspx My 2005 XB9SX easily gets 48 MPG cruising in the soggy air of Florida and 58 MPG in the Smoky Mountains while blitzing the twisties. My 1125R only has 1500 miles on it but has yet to beat 32 MPG which is appalling for a motorcycle IMHO. I'll concur with most of the above reviews that the XB is more "unique" than the 1125 based on its more "characterful" dinosaur-tech motor. In terms of absolute capability, the 1125 is on another planet, but my XB is like the American version of a Ducati Monster - full of character and a ton of fun when ridden in isolation.    Another thing I almost prefer about my XB9SX is that the 85 or so RWHP allow you to give it fistfuls of throttle in the twisties and really USE the motorcycle to more of its limits, giving great satisfaction when doing so. Riding similarly on the 1125, especially higher in the rev range causes more brow sweat and may end up with you in the weeds...

Nice ride jeff. | ||
| Brumbear |
I agree but I still can't stop riding the CR just because | ||
| Vagelis46 |
Jng1226, nice style man. These guys weighted the 1125CR at 458lbs... http://www.motorcycle-usa.com/78/4510/Motorcycle-A rticle/2009-Buell-1125CR-Comparison.aspx The "fistfuls of throttle in the twisties" is more down to the "big bang" characteristic of the XB engine, not the less power compared to the 1125. IL4s that make 100RWHP, slide more than a 100RWHP XB12. | ||
| Moosestang |
These guys weighted the 1125CR at 458lbs... I didn't see where they said they weighed it? They could just be repeating specs. Did you notice they only got 119hp? Didn't sport rider just dyno one at 132 and 135 for the ducati? | ||
| Jng1226 |
Motorcycle USA got 122 RWHP out of their 2009 1125R in the same review I linked to above. Most likely a difference in dynos. Jeff | ||
| Moosestang |
My point Jeff, was that 119 vs. 132 is not just a difference in dynos. Possibly a different tune. Both articles dynoed the ducati the same 135 vs. 136. |
