    Ajax Oilfield engine. www.youtube.com/watch?v=27sL4PXF0dQ
    :rofl
    440 Cubic inch single cylinder cross head two stroke. 20 horsepower, at 400 RPM. Weighing only 5,200 lbs.
    10,000 hours (That's over 12 months continuous) between oil changes
    200,000 hours between re-ring.
    Typical sevice life - 40+ years
    Most parts still available.
    I'm pretty sure I could get 3 more HP out of it with a tuned pipe, but the pipe would be around 36 FEET long

    Here's a few: airhead BMW boxer twins, Goldwing GL1100 , Honda 750/900/1100 DOHC fours from the 70's/80's, Honda GL1500 six,
    DR650 Suzuki, Kawasaki KZ1000 DOHC fours from the 70's, all these are pretty tough. Anything will hold up a long time these days, just change the oil frequently.

    This whole discussion hinges on your defination of "reliable". Reliable as in "I wouldn't hesitate to ride it across the county"? Or reliable as in "I would not only not hesitate to ride it across the country tomorrow, but I fully expect to do it every year for the next 20 years".
    I had no qualms about riding my massively modified Mach III from SoCal to Ohio and back. I knew, however, that it wouldn't do that indefinately. My /5 will.

    I did say it was subjective :D However, I suppose I intended the question
    as in - a long haul bike, across the country and beyond. a work horse
    suitable for an RTW trip if need be. :thumb

    Okay then, I vote for twin shock airheads - with points. The only time my /5 stopped running was on a trip was when the aftermarket electronic ignition took a dump. I pulled off the highway and put the stock parts back in, and rode on. They don't make enough horsepower to hurt themselves, they're simple, and easy to work on.
