The Maxtra 125 is a race motorcycle manufactured by Haojue to race in the Grand Prix motorcycle World Championship. Its first season was in 2009.
The engine design is innovative for a 125cc racing bike: the cylinder points downwards, rendering several possibilities in the intake system and in weight distribution. Also, Haojue will try to improve the 125 by developing aerodynamics of the bodywork.
