    Anyone settle an argument? Stuck in my memory is that Triumph's
    Trophy 500 in the sixties weighed a tiny 330lbs ----- my mate does not
    believe a 500 twin could be built that light.

    You may be right, but I'm with your friend.

    IIRC, the Thunderbird was 8 lbs heavier than a Vincent big twin...

  4. ISTR the Guzzi V50, shaft and all, weighed about that.


    Dry weight 160kg - 352lbs. And that with a shaft.

    You don't RC - even the Lightning with its magnesium & aluminium was
    significantly heavier than that.

    Thanks for the quick and helpful reply. Crazy, that with 21st century
    advanced materials / miniaturization, and scientific product
    development, bikes have not become lighter.

  7. Just how ignorant are you?

    Nowadays some 750-1000cc bikes weigh little more than that.

    If you look at power to weight ratio rather than engine size, they have
    effectively become much lighter. A modern 250cc enduro bike will run
    rings round a Trophy, & weigh around 260lbs.

    They have, relatively. My ZX0R weights 386lbs, and yet produces 4 or
    5 times the power, and around twice the top speed. The forces
    generated when using this power and speed (together with the grip
    afforded from modern tyres) are many, many times greater than the
    Triumph had to deal with, and yet the weight is less than 15% higher.

    Okay, okay everyone, I was wrong, and ignored the power-to-weight
    thing. But we DO have some rather porky litre-plus bikes on the road
    ---. Put it another way, how many 1960's bikes weighed 550-600lbs?

    I've got a T90, which weighs 3cwt, three bags of coal.
    The way things are going will soon be worth less than three bags
    of coal.

    My AJS 38/2 *FELT* as heavy as that, but probably wasn't.
