Well, Lifan's KPX and the Zuma (Wuyi Zuumav) Templars are dual sport bikes based on the Honda CRF 230F engine (bumped to 249cc). Both are AIR cooled. The KPX adds EFI, which is why it's so much more expensive than the Templars. Working a bike hard in single track or in hot weather can get these engines real hot.

The Zongshen NC300 is a water cooled engine, and it is a DOHC six speed. Much better engine temperature control protect the engines better. The Trailmaster TM38 (has been around for a while now) has the water cooled 4 valve SOHC 297cc engine and it is available in EFI (with led lighting) or carbed version for ~$4000.

So here we have a DOHC 4 valve entry (finally) from Trailmaster, using a 283cc head. I think the valves are probably larger diameter (need to verify). This would increase performance at the 283cc level. They are offering one with DOT lighting, and a "Pro" model which appears to be more race oriented for about $500 more (no lighting).

I want to know more about these engines, and the differences between the standard and the Pro models. I'd love to look closely at the welds, and the components. They might very well be much closer in performance and durability to comparable Japanese race bikes.
