I was hearing that the yz 125 and 250 2stroke were the same bike and motor but with different jugs is this true?

No, the motors might be similar in design, but not the same thing. The rest of the bike is pretty similar, though

While many components are the same (bodywork), and many parts are nearly identical (suspension, running gear), the engine and frame are unique to those bikes. They may appear similar to each other, but a closer look will reveal that in no way are the YZ125 & 250 engines the same "except for the jugs", and in no way are the frames the same.


Someone was talking out of their hat. Call him out on it.  :naughty:

Thx I will
