How do manufacturers determine "dry weight" I think there is some inaccuracy to the term "dry weight". I've done the math a few times, using different assumptions and I still can't figure out how some manufacturers come up with "dry weight" figures. For example, oil is about 2#qt, coolant 2#qt, gas about 6.15# gallon. So 4 quarts of oil + 1 gallon coolant + 5 gallons of gas is less than 50# so a dry weight of 375# should equal a wet weight of about 425# at most, which is not what we are seeing. If you add fork oil that still should not amount to much. Dry weight should mean a road-ready bike less all fluids. Really, bikes should be compared "wet" except for an empty fuel tank. That would be more apples-to-apples. Dry-weight really has no practical meaning. | ||||||||

Sometimes it doesn't even include the battery, so thats 12lbs. | ||||||||

It's pretty much a lie to make the numbers look good. You'd think it should be a road ready bike without the fluids...but it never is. Every manufacturer does it. | ||||||||

They all do it, but it's a weird calculation since I've yet to find one that will run dry ... At least not very damn long  Mike | ||||||||

Might be of some interest- http://www.sportrider.com/weights_measurements/146 _motorcycle_weights_measurements/buell.html Although I seem to recall them saying 455 for the 1125 in an article comparing it to the Ducati Streetfighter. | ||||||||

It's not a lie. It's an old hold-over and industry-wide convention from what used to be the shipping weight of the bike. The battery was not included. | ||||||||

I think 455 wet is more like it. My CR weighs 440 wet with an aftermarket exhaust that probably weighs 15 lbs. less than stock. | ||||||||

Many manufacturers are starting to list wet weight and at least Honda seems to be pretty accurate. I have seen magazines put street ready Hondas on a scale and have it read within a couple pounds of their claimed weight, and the claimed weight tends to be heavier than actual. | ||||||||

If the dry weight doesn't even include the battery, why even bother? The dry weight becomes very meaningless. Erik Buell Racing should provide something similar to what Honda is apparently doing. Road-ready weight either with or without gas. Or at least a weight that specifies what is included in the measurement. Maybe a little blurb about how the other manufacturers calculate dry weight would not put those manufacturers that do it more accurately at a competitive disadvantage. | ||||||||

"If the dry weight doesn't even include the battery, why even bother? The dry weight becomes very meaningless." Not if you are comparing different bikes using the same "dry weight" standard. You can easily discern the wet weight from the specifications that Buell.com provides. For the 1125R:
Full wet weight is simply GVWR minus Load Carrying Capacity, so wet weight (full tank) equals... | ||||||||

The trouble with using full wet weight is that some bikes have significantly different fuel capacities. I think full wet minus fuel would be a good standard for comparisons. | ||||||||

I agree. | ||||||||

"Not if you are comparing different bikes using the same "dry weight" standard." Is there a dry weight standard? It is meaningless because some bikes are air cooled, some have 3 qts of oil while others have 4, some have a 3.5 gallon fuel capacity while others 4, 5, or 6. Some bikes have a separate sump for the primary and another for the transmission, wide tires vs skinny, etc. | ||||||||

anybody got a scale? fuel one up weight it and let us all know | ||||||||

I think the consensus is about 455-460 |
