1989 | COBRA

Naked 250 cm³ street sportbike


The COBRA combines an agile-looking naked exterior with unique design features, highlighted by the radiator cover and parts around the lights to create a totally fresh look completely different to any previous race replica model. The liquid-cooled 4-cylinder DOHC engine of the GSX-R250R is tuned for riding on city streets and mounted on an ALBOX frame. The intake system combines a downdraft slingshot carburetor with a straight intake flow for swift response. The chassis adopts radial tires, large-diameter 310 mm single floating disc brakes (the same size as those usually adopted on 400 cm³-class bikes), and 4-pot calipers with different diameters to realize an excellent balance between riding stability and powerful braking force.
