    That is just a brilliant photo, a fantastic image. I can testify to the difficulty in getting a shot that good. I'm guessing a (much) bigger lens than I possess and also closer to the actual course than we are allowed (for safety reasons).

    Well done to photographer Dave Kommel. :clap

    The 2 main solutions for cars is either add horsepower (and weight for traction) or use aerodynamics (with light(er) weight).

    Here are 2 of the latter, of interest because they run bike motors.

    The first one ran a 500cc Suzuki square four 2-stroke, tuned for top end, and started life in the USA as a junior dragster for drag racing before being converted for LandSpeed. It is good for 200mph+.

    The next one used a Hayabusa motor and was also good for well over 200mph.

    The lady in the photo came to Bonneville and set motorcycle World Records eh, bumping up the existing one by some 30 or 40 mph. A considerable acheivement.

    Anyway, here's the second one again, this was the last run it ever did, a record attempt.

    That's a 200mph-plus pencil-roll, extremely fatal usually. The driver actually died twice on the salt but was revived both times, air-evacuated, and amazingly lived to tell the tale. When it goes wrong it can be truly frightening and spectacular.

    Sadly, I was fooling around with F-stops when this accident occurred and I just had to shoot at F-22, which is why the image is a bit grainier than it should be.

    This is Stuart Hooper. The bike is a mid-1950's Velocette 650cc single. It has been officially timed at 193 mph. You read that right.

    Unofficially, it did 197mph at the next timing mark, but he hadn't elected to go that far before he ran so it was discounted.

    Here's another 650.

    And this is build is a little 125cc postmans bike, turbo'ed to the max. (There is also a supercharged version too.) It goes hard (until it blows anyway).

    Some of the bike folks use turbos for supercharging. Adapt a toothed wheel to the crankshaft end (usually the alternator end) and belt-drive one side of it to the drive the impeller side with a toothed wheel mounted there too.
    It works rather well, and the turbos are a measly $100 second-hand, a whole lot cheaper than a proper dedicated supercharger and just as effective for the task at hand.

    I'm searching for a photo of @TinyLambert 17,000 rpm CBR250RR with a home-made supercharger adapted from a turbo, but I can't seem to find the photos.

    At Bonneville, you simply turn off the highway at Wendover and drive onto the salt surface - pretty convenient eh.

    Here in Australia, you turn off the sealed road at an abandoned ghost town and drive/ride for a good 3 hours or so into the start of the outback.

    Firstly, is the road actually open and traversable? I rolled up in 2011 at this turnoff and the road was closed due to flooding and the meeting was cancelled - that's a 1700 km drive to be disappointed and have to turn around. P3050058.JPG


    Then the advice for where you are about to go. It's not a joke either.

    P3050059.JPG

    Rain can turn a road in moments into a sucking clinging red muddy clay that will turn your wheels into giant donuts in a couple of rotations. Or beach you.

    Humour helps in the outback.

    A novel bike being carried in a novel way.

    The constructor/rider is Lucky Kaiser, who is famous for building a 5-litre V-twin by slicing the two end cylinders off a Rolls-Royce Spitfire Merlin engine. It went pretty hard as you'd imagine but handling wasn't a strong point, apparently.

    In the late '50s, twin McC engines were a hot setup on karts.

    Land speed racer AB Jenkins in 1935 at Bonneville, setting a record on an Allis-Chalmers for the fastest tractor. He hit 67.7 mph. It stood for 80+ years.
