The 155Z is coming out of the Zongshen factory, the same factory that builds alot popular Daytona engines. These are not YX engines at all.

We have been testing this motor a while now and have 10 of the 155Z motors in our FXR Atvs racing the GNCC Racing Circuit. We built a few of these engines into 182cc monsters with Takegawa +R heads for our pro riders in Vegas this year.
