Kev....we went back and forth over the weight of a V7R a while back and I told you I was going to weigh it again to confirm my initial reading. So, the tank is kept full during the winter months right up to the top with ethanol free. It was sunny and in the mid 40's around here and my plan was just to run to the scale and back, but one thing led to another and before I knew it, I had 55 miles of casual around town riding on the trip meter.
When I pushed it on the scale it was down prob exactly one gallon from full (as I average 55+/- mpg) on it with uninspired riding.
On the scale:

Scale reading is 429 (that's with 4.5 gallons on board)......subtract 27.4 pounds 6.1 to 6.3 pounds per gallon depending on who you believe) for gas and total weight is right around 400-403.6 +/-pounds. Tires are the stock Sport Demons...stock innertubes with no slime....bike is basically unmodded except for MG OEM belly pan which weighs ounces at best.

Had plans to haul it over to try out the Kendon UTV trailer I modded for hauling bikes but was too nice not to ride.

Well done.

Now you have made me curious to what mine weighs since I have the Mistral Short Exhaust, billet aluminum rear sets, aluminum handlebar, etc.
The next warm day I will ride the V7III to the scales.

Interesting post. Thanks.
Might you have part number or nomenclature for that belly pan?
I was not smart enough to find that in a web search.
Grazie.

Much lighter than I assumed!
Gosh dang, I didn’t realize weighing your vehicle was so readily available. Penske has two public scales within 10 miles of me. I’ll have to take my modified and farkled V7 down sometime and report back.

Interesting, I think many of us will now be curious to weight our bikes
Only problem is, where can one go locally and who will do it

Penske shows where one can find their public scales. Type in your location for results:

I'll take mine to an Grain Elevator in town.

If you have a grain elevator close by just pull on the scale.

Just search public scales near me. If you allow your phone to know your location all the public scales near you will come up. The one I normally use only weighs one axle at a time, but I could put the bike on there sideways. Called today and the scale is broke permanently.
The next closest is a full big rig scale and I am skeptical about the accuracy at the 400 lb range.
I guess you could roll the bike on two bathroom scales if you put some 2x8 between them and a piece on either side. Then you would even get the front to back weight ratio.

A big rig scale doesn't have enough sensitivity to give you an accurate weight. Due to tolerences it it could off by as much as 20lbs either + or -., unlikely but possible. When I raced outboard kneel down race boats I used bathroom scales to check weight. One under each tire and one under the front support of the boat dolly. You can usually find bathroom scales at thrift stores for next to nothing. Put one under each wheel and the third under the side stand. Don't try to just use one and shift it around, you won't get an accurate weight.

Ok, I finally sat down for a second.
Looking back the Owner's Manual claimed 436# "curb weight" so presumably wet.
You got 429# down a gallon, makes it sound like the OEM number was spot on right?
Don't know why we should be surprised at that.
I'm sure there are mistakes in specs, even some of purpose once in a while, but OEMs probably know the truth will out eventually.
Thanks again for taking the time.

I was a welder-fabricator as a young man building commercial truck scales for Fairbanks-Morse. We tested them by placing 1000# and 500# weights on the 4 corners 1 at a time. They were tuned to be correct within 1 #.

I was a weights and measures inspector and sealer for just short of 20 years. It was rare to find a scale out in the field that had a sensitivity of less than 10 lbs. I had a favorite scale that would register accurately at 5 lbs. I used it to get an accurate weight on my weight truck. I would park the truck on the scale and balance the beam it didn't matter what the beam registered. Drive the truck off and re balance the beam using certified weights. Add up the weights and that would be the true weight of the truck. Then I could use the truck plus all my 1000 lb weights to test other truck scales. It was more complicated than that but that is the synopsis.

Objective data. :copcar: Thanks !
Lighter than I thought. I figured the factory lied by about 20 to 30 pounds but I guess not.
-
Any idea how accurate the scale is, now that we know some are better than others?

A crane scale will give you a pretty accurate reading, digital scales have gotten quite cheap. These can be hung from a suitable overhead mount, a 10 foot length of 3" ~ 4" diameter schedule 40 pipe spanning across at least 4 roof trusse or rafters will easily support a motorcycle

For $50 a decent hanging scale

Scale is calibrated on a reg basis. Don’t know last time but could prob get that info. Company uses it (among other things) to get accurate weight on hazardous waste.
-
The date of it's last test by weights and measures will be on the seal placed by the inspector or a sticker placed by a scale company. This is the way it is done in California. Most weighing and measuring devices are tested annually, some once every two years. I found that propane dispensers were the worst for going out of tolerance followed by fuel dispensers. It was a fun job until I moved into administration then everything went to hell.

The factory only lies on horsepower…

The place I used to sell scrap metal to became too far away when I moved. Looking for another place led me to a scrap yard that weighed you vehicle going in and coming out and paid on the difference. I had about 30 lbs of aluminum and the scale reading didn't change so they got my aluminum for free.
I'll be looking for a different place in the future.

That's a case of using a scale that wasn't suitable for the use, high capacity scale for a light weighment. I don't remember the exact language of the regulation. It is a violation of W&M's laws and regulations. I would be doing an Administrative Penalty or a Request for Complaint to the DA. I didn't have citation authority. Another example would be filling a 5 gal propane cylinder from a propane delivery truck. Those meters are not to be used for under 20 gallons per minnute deliveries. Scales will have similar restrictions.
