My brother had 220 from 6 years, he recommended but I went for 150 for its milache. Suprisingly its good, fast and efficient. Riding this bike for 3 years no problem completed 50k kilometers recently. Engine is smooth, I use full synthec oil. Fuel efficiency of 50 is there from the start. Had wiring issues, got it replaced for 1k.
Till now no major repairs.even engine bore is sealed.
