    So, they copied the Honda 450 bore and stroke, it's down a point in compression...



    They are claiming all of 31hp @ 7500RPM, 31ft/lbs of torque at 6500RPM.



    A CRF450X, stock with good jetting is 45hp @ 8000RPM, 31.5ft/lbs of torque at 7000RPM, rear wheel. ( CRF450X Photo Gallery by James Dean at pbase.com ) People are claiming 47hp to 49hp out of stock EFI 450Rs this year...



    So, wonder if they copied the Honda close enough to swap in a Honda piston, cam and valves? (At $1200 a piece, minimum order of 50, I'm not going to be the first to find out.)

    i would be more concerned with the kickstart gears not crunching like saltines, along with the transmission. The chinese have more of a power transmission issue than the power part its self.



    I have a picture of a chinese frame that would be sick to see this motor in...

    actually it does have a linkage, that swingarm is upside down, the engine is a direct bolt in for a Handa, and pretty much a copy, they have a complete bike almost the exact same, with only minor details changed (10%+ difference).

    Interesting. I guess I should ping the .au forums and see what people are saying about it. For that price, I'd be up for trying to race one to see how it shakes out. Motard or GP-Mono style... :P



    Got any plans to eval one NCC?
