Yep the Tracker looks to be based off the cheaper spec Mulhacen as the originals had USD forks as the Senda DRD and GPR. In regards to the engine it looks like an old CBR 125 engine especially in the cylinder and rocker cover. They're only offering the 125 so the images with the 300 much just be the only other pictures available for now. When they finally come out will have to see what engine is fitted as all the side shots are either of the Piaggio or Chinese motor which have been shown at shows with either
