QA's all used the same push rod motor, the yellow tank bike could be a QA50 K0, the red tank bike maybe is a K1, all have a 2 speed box, K0's had issues with second gear, there was a factory upgrade and all use plastic guards not steel, motor in the red tank bike is wrong should have same motor as the yellow tank bike.
