  • Sportster weight.

    Took the Sportster for it's MOT last wednesday (glad to say it passed) and whilst there I asked for the axle weights. As I operate the relevent swiches and controls during the test and the tank was full of fuel at the time, the front was 400kgs and the rear tipped the scales at 510kg. I don't know what a tankful of fuel weighs, but I weigh 77kg approx so my guess, without driver and fuel there is a very nearly 50/50 dry weght.

    A gallon of petrol weighs between 6 and 6½ lbs. Unleaded that is !!

      Goodness me Ben, you should know we use the metric system in this country. You should have said “Four point five five litres of petrol weighs between 6 and 6½ lbs”. (Smiley face!)

        There are quite a few VOSA operateted weigh bridges around, usually combined with commercial vehicle testing centres.

        I had had my car weighed at a site next to the A23. Free if I didn't want paperwork and a small charge if I did.

        If you have a council waste site nearby, they are equipped with weighbridges, it might be worth asking, you never know!

          I'm fairly sure all Mot stations have to be able to weigh the axles to assess brake efficency.

            Yours didn't! But for a commercial vehicle tester it's a requirement.

            I think everything is now recorded by DVLA, almost certainly for modern cars.

              See even you Paul couldnt work out what 6lbs is in kilos(and I cant be bovered)
              The reason we use metric litres for fuel is so you don't realize how much a gallon costs!!

              Count down markers on motorways are still in yards

              Road signs in miles

              and most important beer in pints!!

                Spirit measures went metric in 1985!

                  I think you may find that an Imperial gallon of petrol weighs in at around 7 1/2 lbs or 3.4kg. None of this colonial short measurements for me - you get a fuller measure in the UK.

                    OH the dreaded US Gallon I wondered why my maths didn't work out.

                    1 gal imp water weighs 10lbs and the specific gravity of petrol is around point 7 so there you go !

                        Ben : those "pint" measures - are they the glass things which always seem to empty very rapidly, and more so as the evening wears on ?

                          Re: Sportster weight.

                          SG of petrol is 0.73

                          So every litre weighs .73 of a kilo

                          Metric does make the maths easier

                          I still like pints of beer though

                            Is a half empty glass heavier than one that's half full.

                              Ok so does the Northern beer with its injection of gas to make it frothy weigh less than a pint of traditional non gassy Southern beer like Speckled Hen or Doom-bar( if you like West Country ) or Gales for you Hampshire folks
