I have gone for Suzuki and placed an order for Gixxer SF, is it the right choice?

Yes. Better than Yamaha's offering.

The Suzuki Gixxer SF is an excellent choice as the bike comes with an aerodynamically tested design and body language, making it best to ride on road and tracks. It comes with the same engine being used in the Gixxer 155, making it a reliable machine with 154.9 cc, 14.8 BHP engine. It comes mated to a 5-speed gearbox and equipped with a front 267 mm of disc brake. The design features a fully digital instrument console, again carried over from the Gixxer 155. You have opted for the correct bike and the choice is absolutely right as the bike returns a 45 kmpl fuel mileage also.
