Hey guys, I'm mucho late on this one but thought I'd stick it up there for reference anyway. These images were snapped at the 2010 Cycle World Expo in Washington DC earlier this year.

No interesting C-Motos to report at the Expo but I did managed to take some pictures of common engines that may be found in our Chinese bikes for reference/comparison.

One last note for the motor-heads, be sure to check out the Yamaha YZ450F engine internal cut-away/cross-section display at the end of the post. Reverse intake design engine is worth checking out!
