    Tell us more about what this engine is? Is it the same as what comes in the 125 Raptor?

    As a mod motor, that would not be enough... And unfortunately it's not a production legal engine. It'd have to compete against the 150R Honda...putting out 25 plus HP. Sure would be cool if Yamaha would put it on the Raptor....then they'd have something.

    Possibly a useful 90 mod four stroke option.

    The 150 is only in the super mini. There isn't any option that i know of for the 90 mod four stroke.
