I have yet to see a motorcycle being offered that has Loncin water cooled 250 that mirrors the specs of the Honda NX25O I have only seen motorcycles that have a SOHC water cooled 250 that are made by Loncin and also the same scenario for Lifan and Zongshen for that mater. It is not that they cannot or do not offer a copy they just do not have any in a production bikes to the best of my knowledge. Unless Shineray is not making its own engines, I believe that they do, but I could be wrong.

A company called Dongben is offering a 300cc water cooled DOHC, maybe that is not an NX250 bored out now that we have discovered that there are copies of the KLX300 engine.

For air cooled I like the 223cc OHC there are also 200cc versions as well, the Honda copies.

The copy of the NX250 is all there really is that offers performance in the realm of china.

There is also the Suzuki 250 and 200 as well, but neither are setting any performance benchmarks.

So as for bang for the buck the Yingang seem to be the winner winner of a chicken dinner.
