The SZ-S is a premium 150cc commuter motorcycle from Yamaha. There is nothing sporty about the looks of this bike but it also isn’t a dumbed down version. The SZ-S is powered by a single-cylinder 153cc air-cooled engine that churns out 12bhp and 12.8Nm of torque. This engine is mated to a five speed gearbox with one down and four up shift pattern. According to the Japanese bike maker, the SZ-S is all about optimum performance and good fuel economy. The 14-litre tank need not require filling for 600kms and this shows its efficiency.
