What is the wheel size of Suzuki Gixxer SF 250?

250 cylinders , unlike Yamaha R15 v3 Which has 150 Cylinder

The Suzuki Gixxer SF 250 is equipped with tubeless tyres.

Suzuki Gixxer 250 SF is powered by a one-of-a-kind oil-cooled engine. This 249cc single-cylinder engine is a purely oil-cooled motor with no fins on the cylinder block. The engine churns out 26.5PS and 22.2Nm mated to a 6-speed gearbox. The 6-speed gearbox feels really slick, slotting positively every time you need it to. Made with supreme tractability in mind rather than outright performance, this motor feels strong at slow speeds, and can carry speeds as low as 30-35kmph in 5th gear. Moreover, we would suggest you to take a test ride for a better understanding of performance and comfort. Click on the link and select your desired city for dealership details.

IMO pillion is comfortable for longer rides. But it will be difficult for the rider as pillion weight come very much on the rider while breaking and it can squash nuts.

M a owner of gixxer SF 250, yes,!!!It has a fan, activates when the oil temperature goes above 200°F

Nope , you need your phone and I would recommend buying a magnetic tank bag with touch screen compatible mobile pouch so that you can easily go.
