Thanks

So, if you ignore the legality of registration etc there should no issues with popping a 250 in that frame? Trying to find someone who has made the upgrade from the 125 but the frame part no. appear to be identical.

So in theory: same lump on the GZ250 and GN250 + Same frame on the GZ125 and GZ250 = no probs... he says.
