Hello guys, my opininon for the Rieju MRT it´s very good it´s my third bike and my first offroad bike. It has very strong engine Minareli - made in Italy and many from the parts also the carburetor Dellorto phbn16 it´s from italy, the bike it´s very good for offroading in the forest and also very good for BIIIIIG hils it´s amazing that with small 50 cc bike i can do big hill climbs. The parts are very cheap there is avaliable tuning kit for Minareli AM6 from 50 to 75 ccm that cost 135 Euro.
