I HAVE THIS BIKE. since 2 month. I loved this bike.
The SF with Fi is powered by the same 155 cc engine that does duty in the Gixxer motorcycle. Since Suzuki hasnt stated just how much the power and torque has increased, thanks to fuel-injection.
We reckon it is marginal. This move comes in at the right time for Suzuki as the Indian government has decided to impose stricter emission norms for two wheelers which requires newly launched bikes to comply to BSIV norms by April 2016. This works quite well in Suzukis favour as the new Fi system should bring down the CO2 emissions by quite a margin.
Along with the FI update, Suzuki will now also offer the Gixxer SF with a 240mm rear disc option with a single floating caliper which is sure to improve the braking capabilities of the motorcycle. These changes aside, the Gixxer SF will continue to bear the same look as before.
