While primarily aimed at younger riders and those looking for a convenient and inexpensive way to get around, the QT50 and MA50 also appealed to seasoned motorcyclists seeking a simple and enjoyable ride.

Both models were equipped with a distinctive step-through frame, providing easy access and a comfortable riding position. With their lightweight construction and agile handling, the QT50 and MA50 were perfect for navigating city streets and tight spaces. The QT50 and MA50 were also praised for their durability and low maintenance requirements, making them a reliable and cost-effective mode of transportation. Although production ceased in the early 1980s, these little Yamaha motorcycles left a lasting legacy, endearing themselves to generations of riders with their practicality, affordability, and pure riding fun.
