Is a zongshen a good 125cc ?

There are many different Zongshen engines. from simple 50cc engines to the top of the line HO engines.
The worlds largest pitbike company ,Pitster Pro, is using them as their primary engine line on their pitbikes and their crate engines.
There is also a reason other manufacturers have Zongshen build their top line engines , like Daytona.

I would say yes they are good.

I have a 125 with clutch on the crank. Its been beat to crap by kids and probably never had an oil change before I bought it. It starts first or second kick and doesn't smoke. Only problem so far is when the engine is warm, the shifter is sometimes slow to spring back. Otherwise I'm happy and I ride the crap out of it.

Actually you would be partially right, I took the YX engine and added parts from the rest of the industry, BBR Taky, Lifan, and YX, also some of my own parts, IE 6 disc clutch etc. I then built two engines and personally took them to the Zongshen factory to develop a new performance engine. The YX engines , the bigger ones were a nightmare and reliability was not one of thhe strong points of those engine. The standard z 155 can first as it was easlier, then the HO engine came about 6 months later. This was early 2008, the general public got the z engine in June 2009 and the HO Jan of 2010.
Zonshen is the second largest manufacturer of small engine like these in China, YX is about 20th in size. Zongshen has a much better manufacturing process. YX has improved quite a bit over the last few years.

Good choice. I'd argue that Lifan and Zongshen are exactly the same, and I beat my Lifan to absolute sh*t and she still runs strong. It's a 2004 Lifan 125 with the hideous 1 dwn 3 up tranny and I used to hard shift it and ride it like I stole it. Hell, I flipped it once back three years ago and the peg failed to bend and it took a quarter size chunk out of the case along with a peg mount bolt. We sealed it up with what I believe was coolant line sealant puddy or something to that effect and fired it up and ran it with three peg bolts, jumped it, thrashed it, didn't change the oil for probably over a year after and it still has that oil in it today. It's pulled out of the 50 for a Honda engine, but I'll tell you what, I wouldn't hesitate to ride that power plant in MoM tomorrow if I had to.

Here are some pics of the "repair."

No remorse for that China engine and I argue its held up just as good if not better than a Honda.
