    Hey guys, Ive the following question, Ive read a lot of info in websites where people say the 230f has 16/17HP (stock), but here on Chile, its marketed as a 19,3HP bike @ 8K (honda site)Is it that the newer models 2014> are different or just not reliable figures?? I undertand were alesys talking about Brazilian bikes, here lnly diff is they come with headlight.

    It depends on whether it is stated in imperial brake horsepower or the DIN equivalent.
    One horsepower is the equivalent of 746 Watts while one PS is only 735 Watts. When you compare PS to BHP, you get a coefficient of roughly 0.98.

    I know that doesn't account for the difference here but they way it is measured, with or without accessories, directly on crankshaft or after transmission losses makes a difference.
    Unless you know the test condition it is hard to tell. I believe the 16/17 horsepower stock. If they have changed the head, cam or carburation on your model bike from say my 2004 model that may account for the difference.

    A few hp increase is quite noticeable on small bikes.

    Mike Coe dynoed an uncorked CRF@30F with proper jetting (120 main) and saw 17.8 RWHP.

    In stock trim I doubt they even produce the 14 RWHP of a bone-stock XR200.
