my ride: DHZ 138cc lifan. 55mm hc piston, inner rotor kit, pro taper bars, pro taper grips, kenda carlsbad front and back, ngk spark plug, dvs sticker kit
The first had a stroke of 54mm and bore of 54mm which makes this motor 124cc. Plenty still in circulation. They are basically very similar spec motors to the Ducar.
The second motor which is the more sought after engine, has a stroke of 55.5mm and bore of 52.4mm and was only a 120cc engine.
Now Lifan has discontinued the first motor but released these new 138's. They are just the second motor above with the 55.5 mm stroke, but fitted with the 54mm piston from the first mentioned engine. They have 138 stamped on the barrel, but are only 127cc!
Now I have heard one person claim that they bought a Lifan with a 56mm bore which would give you 137cc, but this can only have been done by another chinese company either copying the Lifan motor or reboring Lifan cylinders to 56mm ex-factory. I don't know if he really did have a 56mm Lifan motor though.
So, you'll have to email the seller of that kit to find out. I'm sure someone on here has bought one by now so maybe we'll find out that way.

yep mine had a 56mm piston but is was fitted by the seller, but i have since ditched the 56mm low comp piston( steel barrel) and opted for a new barrel (alloy barrel)and a 55.5 high comp piston. You are correct but Lifan now have a 140cc which is 55x59 it will be here very soon. It uses the 120 monster bottom end ( clutch on the main shaft and all up tranny). I will let you know how it goes
What size piston is in this ebay kit from dhz, I have asked but no replies, it uses a 14mm pin, 54x54 use a 13mm I think and 52.4 x 55.5 use a 14mm and 54 x 57.5 use a 13mm, just be sure to check yours.
yep straight from the Lifan factory , i think they have a steel barrel but that will be ok, if you want to run a alloy barrel you will just have to KLX 110 sleeve it, this will not be my race bike motor just weekend worrier bike. I have had reports from a few people who are running them and they say they absolutely kill the 138. It will be interesting to see what they can be taken out to, i have a 57mm piston on its way will be great if it fits that will make it a 150.55cc, inner rotor , big cam, port and this should make a rocket ship. I will keep you posted on it
