    200X Horse Power?

    Does anyone know how much horsepower an '83 200x produced? I'm restoring one right now and wanted to know.

    Just had a look in my Honda manuals, and the 83-85 has 18ps and the 86-87 has 19ps. Converting this to HP I think this makes the 83-85 17HP and the 86-87 18HP

    Wow...What did the ATC 500R have again? Just kidding...I think it would have been at about 49 to 51...damn!!

    Gotta love the KX 500.....Dirt Bike says it puts out 62 at the rear wheel..stock!! Oh God...I love that

    Late 80's engine is still the fastest ***EDITED** in the world!!

    The KX500's liquid-cooled 499cc two-stroke engine features the Kawasaki Integrated Power Valve System (KIPS), and pumps out nearly 65 horsepower for incredible off-road speed and acceleration. Powerful disc brakes in the front and rear rein in those ponies, and fully adjustable suspension components provide more than 12 inches of wheel travel.

    The ATC110 motor is usually listed at having 1 more pony than the 90, which gives it 8hp. PS is an alternate unit of power measurement (I believe its derived from German). Japanese PS = @ .90 of the SAE net American Horsepower. I suspect that many european destined Japanese motors in ATV's had more horsepower than their American counterparts - this has been true for almost 50 years of Japanese motorcycle exporting. The American market has much tighter restrictions on power output (this is also why you almost never see horsepower quoted in any American manual or advertising.) It may also be part of the reason why our motors respond so well to exhaust "Modifications". Again though, through many years of articles, research and bits of dyno information I've seen, any American ATC200X from 1983 - 1985 is only going to have 12hp at the rear wheel from the factory, '86 - '87's were said to have 2 more at peak output - 14hp. Look at it this way - '87 was the first year for the TRX250X, which was a larger displacement, much better breathing 4-valve motor, that sucked fuel through a much larger 36mm carb motor than the 2-valve, 28mm carb'ed 200X of the same year. The 250X's output was only 15.7hp.

    My father has the bike equivelant to the early 200x engine in his racebike but at 183cc and it makes 22hp. Pump it to 200 and I reckon you could get 25hp.
