which is better suzuki gixxer SF or hero karizma
It depends on your riding needs, for normal day to day commute along with a short ride once a month, gixxer seems to be a nice option, but if you love explore the roads then karizma will fulfill your needs. A better service network, better after sales support also it has an option to crank the engine manually.
& yes both the bikes look gorgeous on their terms.
Gixxer SF is a better option if you can compromise in speed which does not matter much.
Suzuki Gixxer SF is a better option than the Karizma R version 2.0 as the Gixxer features a much better design than the karizma. The full fairing on the Gixxer SF makes it a show stopper, whereas the Karizma gets an uneven side fairing, which looks outdated and rough. The Gixxer SF is much more fuel efficient than the Karizma and also has a fully digital instrument console for a better look and finishing.
