    The 250SX has about 12 so I would say around 8-10 for the 200.
    [20:55] <waterpumper> putting a racing pipe on a Foreman is like putting a high dollar bikini on a 400 pound chick...just because it fits doesn't mean it looks cool

    According to our manual the 1985 125m has 8.5 HP, so hopefully its a bit more than this

    My Honda facorty service manual states 18PS@8000RPM (PS is equal to HP i think) and 13 FT/LB of torque@7000RPM for the 250SX.
