    I have an old Ariel Red Hunter 500cc single. Being old and pommy why
    is it in cc and not in cubic inches? I think some of the early
    Harleys were quoted in cubic inches but everything else in cc's. eg
    Norton 750 BSA bantam 125 Even the bore and stroke are given in metric
    81.8 x 95 but the threads and all other measurements are all imperial
    any logic to this apart from pommy logic?

    Australia (and Japan) have been metric for decades. How come my bike's got
    18" wheels?

    All English motor vehicles have from time immemorial (i.e. since before I
    was sentient) been measured in metric. Never at any stage have they been
    measured in cubic inches. It's the Yanks who love cubic inches. I think it's
    because (shock, horror) the English didn't invent the motor car and they
    used the European conventions.

    The only exception was where they calculated RAC HP where they have a
    formula that uses the bore in inches. But that has nothing to do with
    capacity, or horsepower.

    The bit I like is where the tyre says something like 120/90 18. Meaning it
    is 120 mm wide, 90% of 120mm high, on an 18 inch rim. A great mix of

    Same kind of [pommy] logic probably responsible for metric size wheels on

    You should worry, the seppos sell peg mounting clamps for the Vulcan (a
    Kwaka metric cruiser) as 1.35" - now that's wierd. Everything else in
    the catalogue is imperial!

    Also, I particularly love "Metric Cruiser" as a description.

    From now on, I shall dismiss the V-rod as "... a bit too metric
    for me ..."

    Bzzzt wrong.

    The only Jags ever to get metric wheels were the 88 and 89 XJ40, on which they
    were fitted because they were the "new standard" (read as they were the latest
    and greatest bells and whistles) - Merc and Bum Dubya got sucked in by it
    briefly too. When everyone figured out it was the auto equivalent of OS/2
    (technically better but insufficient support by the unwashed massess) they
    ditched it

    ok there were no Jags fitted with metric wheels.
    ok there were Jags fitted with metric wheels. make up your mind :p
    And some Australian built Fords too... Fairlanes and LTDs in the late 80s.

    Were they those "reinvent the radial tyre" spoke-pattern mags that Michelin were pushing? (The line was that
    existing rims were designed for crossply tyres).
    Fairlanes from about 1982 (XE equivalent) had them and then they disappeared.

    were pushing? (The line was that
    No these were a new tyre type that were supposed to be among other things, "run
    flat", they had a metric diameter of X00 mm (500 odd I guess?) instead of 16"
    or whatever. I've never owned one so I don't know that much about them, they
    failed to be successful.
