Cycle world mentioned the dry weight of the Firebolt is 429 lbs. Is this true? If so this bike is a tank. My M2 must weigh over 500 lbs if that is the case since it looks a bit larger. Also, Cycle world mentioned the Firebolt was heavy steering. Is this true too? I though the Firebolt was flickable like a 250 GP bike. I do not believe everything I read this is why I ask these questions. Thanks Mike | ||

Ya know, when they weigh a bike, I believe it should specify what ISN'T on / in the bike that would be required for operation. Air in the tires, lubricants, coolant, battery, fork oil, whatever. For example, "We drained the fuel and engine & tranny oils from the bike and weighed it at a portly 429 pounds." EVERYTHING required for normal operation NOT INCLUDED in the weight should be explicitly mentioned. Just an opinion... -Saro | ||

Chris Dolan in San Diego weighed his full of fluids and it was a touch under 450 lbs. Vuj | ||

Cycle World generally weighs bikes with all fluids except for gasoline, though that has varied historically. For a while it quoted two weights, tank empty/tank full, which was useful for comparison purposes. Gas is right on 6 pounds a gallon, so figure around 22 pounds of gas (3.7 gallons)in a Firebolt. 450 pounds of Dolan's bike minus 22 pounds = 428 pounds --- about what CW measured. Japanese standards for specifying motorcycle weight, as far as I understand, are for a shipping weight: no engine oil, no water, no fork oil, no battery, certainly no gasoline. They typically understate weight by at least 10 percent, sometimes substantially more. Yamaha has recently been quoting a ready-to-ride curb weight in some of its literature that is more realistic. Generally Harley factory specified weights are pretty close. Buell seems to have adopted the Japanese standard with the Firebolt, perhaps for when people compare weights at the brochure. | ||

Aaah sooo, maybe they should emulate Ducati instead, who shows the "running weight" of their bikes in their brochures, which seems more realistic. | ||

If I didn't have any water or fat I'd weigh about 37 pounds. | ||

BMW always show the "running weight" like this for the R1150 GS Adventure: Wet Weight 549lb. (Dry Weight 503lb). (w/all options)/ 609.6lb. Buell could do the same. Seems logical to me, for thats the way you ride it. Grizzly's Adventure (temp. OBCO) | ||

Okay, motorcycle online has wet weight at 425 lbs. I'm assuming this is pretty close since there were enough people that didn't want to like the bike. My assumption is cycle world stated dry when it was wet weight. | ||

Buell publishes a dry weight of 435 lbs for a late model M2. Does anyone know what an M2 really weighs? I'm guessing this bike weighs closer to 450 with oil but no gas. | ||
| José_Quiñones |
Add the following to 435: 5 gallons gas x 6 - 30 lbs 2 qts oil x 2lb/quart - 4 lbs battery/fork oil, misc. about 12 pounds So about 485 pounds | ||

Mfell212, The Firebolt is not a "tank", but is close in weight to a Japanese 600. Check out the weight of the Honda CBR600F4 in Cycle World...the dry weight advertised for the Honda is 370 lbs. Looks like the reality is about right for difference. BTW, check out the weight of the Ducati S4T in the same article...no lightweight there. Wonder what Ducati advertises for it? Buell's are right in the hunt with the best sportbikes...and I'll bet the XB motor weighs a little more than the Honda!!! Can you say world class chassis? | ||
| José_Quiñones |
According to Cycleworld, the "dry weight" of the CBR600 is 408 pounds. The fuel capacity accoring to Honda is 4.8 gallons So 408 + (4.8 * 6) = 436.8 say 437 Firebolt 429 + (3.7 * 6) = 451.2 pounds, say 451 Difference - XB is 14 pounds heavier "wet" Advertised dry weights XB - 385 lbs CBR - 370 lbs Difference - XB is 15 pounds heavier "dry" | ||
| José_Quiñones |
According to Ducati it weighs as follows: Weight * 212 Kg / 467 lbs * = The weight includes battery, lubricants and, where applicable, cooling liquid. CW measured it at 497 lbs, not including fuel. | ||
| Fullpower  |
the term dry weight is an absurd fiction. a functional motorcycle is NOT dry. the M2 weighs 469 wet, including fuel the XB12S weighs 461 wet, with a full tank. THATS THE FACTS. | ||
| Wyckedflesh  |
To the rest of your question, the Firebolt is flickable, on the stock Dunlops with their relatively flat profile the bike is "heavy to steer" , but put on a pair of performance tires with a triangular profile that "heavy to steer" turns into "DAMN FUN IN THE CORNERS WITH A GRIN FACTOR OF!" | ||

Jose, how are you figuring 5 gallons of gas into a XB? '03-'04 CBR600RR is more like 445, the F4i was 435lbs but the 1st generation 600RR is heavier...the '05 model has lost somewhere between 17-20 lbs for it's weight wet (according to several different articles.)....they're all saying Honda was VERY optimistic about the dry weight for the 600RR when it came out. http://www.sportrider.com/bikes/146_Weights_Measurements/ http://www.motorcycledaily.com/04january05_cbr600rrfirstride.htm So a XB12 is 461lbs, how much is usually saved with a slip-on? The Honda 1000RR weighs 460lbs wet, it's not really a heavy bike...the R1 weighs 450, again, no ones calling it heavy. Honda RC51s weigh 485lbs, you can feel the extra weight compared to the R1 but I certainly didn't care when riding both a R1 & RC51 back to back several times on the same day. | ||

485 for a tuber is pretty accurate. My S3T(no bags on it) weighed in, fully fueled up at 702 with me on it at the last Hal's HD Dyno drag. And I weigh about 220. | ||
| Wheelsleaning  |
XB12S = 462lbs wet. My XB12S = 448lbs (Jardine).  | ||
| Nedwreck  |
Still 200 pounds lighter than the Street Rod. Bob | ||
| Brucelee |
Regarding the flickable issue, I have an XB9S and it will run circles around my former ride, an 02 Ninja 600, no comparison. Interestingly, the XB feels much lighter than the Ninja, even though they likely weight about the same thing. Go figure. | ||

Lower center of gravity  | ||

Enp83... José_Quiñones' 5 gallon comment was referring to the M2 not an XB. | ||
| Kowpow225 |
So does anyone know the spec for engine weight on an XB? | ||
| Raraf |
Dudes, in the latest Cycle World, an insider tells how the manufacturers come up with the weight. In a nutshell...They estimate the weight in design and then publish it so it will be ready to release to the Press during pre hype stage. I don't have the article in front of me but I think that is what it said. | ||

The stock exhaust is HEAVY. I've heard 27 pounds. The header/exhaust I just put on my bike took of about 18 or so. The force pipe is a LOT lighter. | ||
| Wheelsleaning |
Basically, whatever the manufacturer says is bull.  | ||
| Wyckedflesh |
My XB12 canister just weighed in at 17lbs using the weight comparison method (weigh one item, then weigh both items and subtract the difference of the two weights to get the weight of the second item) The BOX for my Vance and Hines exhaust is listed at 9lbs total for all of the contents(UPS Digital Scale), that includes 2lbs of packaging (weighed using the above method as well) so I would say that my Vance and Hines put my XB on a 10lb diet  | ||
| Mikep  |
The muffler from my XB9R weighs 14.2 lbs. | ||
| Mikep |
The license plate frame and the steel brackets that hold the rear side reflectors, together weigh one pound. | ||
| Wheelsleaning |
unnecessary weight  removed. What about the passenger pegs and brackets? Change the mirrors, thats weight thats about the farthest from the bikes center of gravity | ||
| Starter  |
You guys might remember the old cbr954 being advertised as weighing only 168kg then the new cbr1000R weighing much heavier at 180kg. Until there is an enforced standard all manufacturers will continue t oGuild the lily. | ||
| Mikep |
The rear footpegs and struts maybe weigh 3 lbs total. | ||
| Mikep |
Some of my calculations tell me that removing 10 lbs is equivalent to ~1.5 h.p. on our 430 lb bikes. | ||

Diet, diet, diet . . . | ||
| Imonabuss |
XB engine weight is around 175 lbs. 600 supersport motors are around 115 nowadays. | ||

Thanks Imonabuss!  | ||
| Ronlv |
so how much horsepower could you gain if the rider lost weight? :-) |
