"Air-cooled, 4-stroke, single-cylinder 153cc engine"

A newly designed 153cc air-cooled, 4-stroke, SOHC, single-cylinder, 2-valve engine with a max.output of 14 Ps and a max. torque of 14 N.m., characterized by its breathtaking pick up and featuring an electric starter.


"Monocross suspension adopted"

A Monocross rear suspension unit provides 120 mm of wheel travel, while optimized oil and damping valve specs help ensure agile running performance and handling. It inhibits bottoming while riding with a tandem passenger as well as providing a very comfortable ride.


"Exhaust efficiency, sound and concentration of mass"

To give a sense of volume to the machine, an external diameter of 35mm is adopted in a two-layer type exhaust to minimize the effect of heat on the pipe. The layout features a large-volume primary character on the underside of the crankcase. The muffler is an irregular shaped tapered type mid-ship muffler.


"India’s first “140/60-17” size radial tyre (rear)"

The rear tyre is India’s first radial tyre with a 60% aspect ratio. Both the front and rear tyres on this model are tubeless type that are less susceptible to sudden flattening should the tyre be punctured.


"Large-diameter front disc brake adopted"

At the front, a large Ø267mm disc brake is adopted. The two-pot caliper makes full use of the outer perimeter of the disc to provide strong stopping power. The optimized specs of the operational parts provide a high-level of balance, excellent initial braking performance and good operational touch.


Front suspension

The inner tubes on the front fork are the first large Ø41mm units adopted on a motorcycle made in India and the stroke is a generous 130mm. With the front assembly dimensions, they provide good shock absorption. The good damping characteristics during acceleration and braking contribute to increasing stability.


"Multi-reflector headlight adopted"

The bulb’s illumination and the type of light unit employed gives greater freedom of design. This creates an aggressive-looking front view and the transparent lens gives this unit a highly stylish image that accentuates the character of the model’s ride.


"12-liter fuel tank with uniquely styled plastic resin cover"

The steel fuel tank with a plastic resin outer cover takes advantage of the freedom of shaping that plastic provides, giving the tank cover a powerful shape with modulations suggestive of the muscular body of an athlete.


"Full LCD meter"

The meters on the FZS are installed in a Full Liquid Crystal Display. The speedometer, tachometer, trip meter, fuel gauge and other indicators are set in optimum position to keep the field of vision clear. Also, the engine starting signal is an example of the spirit of innovation.
