sir, i need some more information about XP6: 1) what is its ground clearance? 2)does the option exist (pre or aftermarket) to make it 70cc with a carburator of 24mm venturi diameter? 3) my weight with all gearing is about 83 kgr and height about 180. is XP6 suitable for me to use it in the MX track (not jumping) with the much sloped uphills and downhills?
