I ordered my Templar X May 10, 2024. That engine authentication sticker is new to me on the three Chinese bikes I have ordered. The rear shock has a date code of 2024/04/01 laser etched on it. Both front and rear bearings had more than enough "clear" grease to the point of excess, the steering bearings also have some blue grease around the stem area.
The more I look at the Zongshen NB300 ZS174MN-5, the more I am convinced it will fit into this new frame. It's engine dimensions are within 5-10mm of the PR250. The CB300RL ZS175FMN looks like it's air cooled clone to a point. The NB300 is offered with 5sp kick and electric start or just electric start with 6 gears.
