i guess if u bolt her on properly and on the right motor it will be fine, they wouldnt make em just to explode peoples engines lol.

They've made a typo on the bore size ... it's 60 mm (161 cc) NOT 64 mm (183.37 cc) ... I can't see the kick starter gears lasting very long ... and if you went thrashing it like it's still a 125 and treat the clutch roughly ... then Kabango to the tranny ...
