Hey mate,

Both are great engines, offering both good reliability and power for their price. The lifan 125's are a tough engine and will last a long time if maintained properly. If had many 1254 Lifan engines and they have all served me well and truly.

As for the yx140's, they are a much better engine then the lifan 140's as they offer the all up gear pattern. The 140 does have a lil more grunt and its reliability is still pretty good.

In my opinion go for whichever one you can get a better price on man!
