If considering Suzuki, must go for GS 150 SE because on simple model brakes are very poor and GS with all its power can be dangerous.
Yamaha has much better quality and finish and is a solid bike. Just purchase and ride. No funny business.
While GS is a bit "nakhreeli" and can have small issues here and there. But it sure makes up for it with its engine. It has good power for touring and no bike runs as relaxed as GS at 90Km/h.
