Yamaha 125 SR 1981

Menus

Custom economic par excellence, the SR is not in the flash but more in the utility with a touch of charisma. Mutineer in an urban environment, the SR is powered by a solid mono 4 T, a little vibrating but reliable, ensuring suitable performance for city use.. Out of town, the mono runs out of steam at around 90 km / h – optimism and patience are then required to grab a little more speed. A head wind a little pronounced and the mechanics do not give anything above 80 per hour. Simple in design, the machine offers correct dynamic performance and significant comfort advantages: an electric starter, a low saddle, and a protective chain guard (clothes will appreciate). Competitor of the Suzuki GN, it is however more expensive than the latter.
