I have just installed a ZS172fmm in my Hawk frame; aka Zongshen PR250. I also have a big bore kit installed on it that makes it equivalent to the ZS175fmm (Zongshen PR300). It is indeed a huge step up for these bikes in both power and usability for both road/highway, and off-road use. It will fit the Hawk/TBR7 frame, but you will have to do some frame modifications. See my post about it here: https://www.chinariders.net/showthread.php?t=33557

I hope this helps!
