64 mph and the piston is so weak
no.
I seriously doubt it. This is something you need to talk to your local Yamaha shop about rather than take someone's word on it here.
top speed of a yz125 in mph
Obviously yz125 is more faster than yz85.
all yz125's are 2 strokes
a yz 125 goes 80mph
No. If it minor pitting, honing the cylinder may be enough. If it is deep, it will need to be bored and an oversize piston used or the cylinder can be sleeved.
YZ125 is referring to a Yamaha motorcycle with a two stroke engine designed for motorcross riding. The Yamaha YZ125 weights 189 pounds dry and 208 pounds wet.
