Thumpstar MX50JR

Bring back the 2-Strokes! For the past year, we have been conducting research and development of one of our most exciting projects! The Thumpstar MX line of bikes. Our design and development team has put together the ultimate 2.5stroke 50cc Package which efficiently delivers sufficient power to compete with the other race-ready bikes in the mini class. At the heart of the bike sits a 49 CC, 1-Cylinder, 2-stroke, water-cooled engine with reed intake that produces impressive power out of the box. The centrifugal automatic clutch provides manageable acceleration and makes learning to ride a breeze.
