KATANA

The high-performance 999cm3 four-stroke DOHC liquid-cooled inline-four engine underwent thorough review as it was developed to deliver ideal performance under varying riding conditions, whether out for a sporty run or negotiating traffic on city streets. Changes that include a new camshaft profile, new valve springs, a new clutch and new exhaust system increase power output and achieve an overall better balance of performance, all while satisfying Euro 5 emissions standards.

The new engine produces greater torque than its predecessor at low rpm. The broader, smoother torque curve has fewer peaks and valleys than before, it also achieves greater overall cumulative torque production across the engine's operating range. This results in more predictable and controllable response and consistently abundant power delivery for a more exciting riding experience, particularly in the low-mid rpm range where the enhanced torque output is most noticeable.
Another development goal was to further enhance the durability of an already highly durable engine design. Attention to detail extends to a change from cut threads to rolled threads for the holes in the upper crankcase cover. Rolled threads are harder and less prone to cracking from wear, so help maximise holding strength for the journal bolts that support the crank.

The new KATANA adopts a collection of the advanced electronic systems that comprise the Suzuki Intelligent Ride System (S.I.R.S.). Included are the Suzuki Drive Mode Selector (SDMS), Suzuki Traction Control, Ride-by-Wire Electronic Throttle, Bi-directional Quick Shift, Suzuki Easy Start, and Low RPM Assist systems.

These enable the rider to optimise performance characteristics to best suit riding conditions and varying road surfaces, as well as their level of confidence and experience. By assisting the rider, they help make the bike more controllable, more predictable, and less tiring to operate, whether out for a sporty run or enjoying a ride on city streets. These attributes benefit the rider by instilling greater confidence and allowing them to concentrate on enjoying the riding experience.

SDMS is designed to offer the rider a choice between three different modes that change output characteristics to match riding conditions or preferences.
Mode A (Active) provides the sharpest response as the rider opens the throttle. It is well suited for use when hitting the throttle hard, such as when participating in track day events or enjoying twisty roads in good weather.
Mode B (Basic) reaches the same level of maximum output but features softer response and a more linear power delivery curve as the rider opens the throttle. The settings are tuned to make the bike more controllable and instil confidence when accelerating, and to make it a good fit for a wide range of rider styles and road conditions in everyday riding.
Mode C (Comfort) provides the softest throttle response and gentler torque characteristics, delivering power in smoother linear fashion while still reaching the same level of maximum power output. The gentler throttle response and limited torque production as the throttle is opened makes more obedient and controllable when riding in wet conditions or otherwise slippery surfaces, or when the rider wants to relax and enjoy an easy ride home after a long outing.

An updated version of Suzuki Traction Control System (STCS) with a wider selection of 5 mode settings (+ OFF), as opposed to the 3 modes (+ OFF) of the first generation. The finer incremental control over settings allows the new 5-mode traction control system to better fit a more diverse variety of riding conditions and styles.

A ride-by-wire throttle system provides finer control also allows optimum settings to best match each of the SDMS modes. The overall result is linear power delivery that responds faithfully to the rider’s intentions, whether riding on the street or heading out to enjoy a spirited run, as well as improved controllability when opening the throttle while cornering

The bi-directional quick shift system allows the rider to shift up or down more quickly and easily without the need to operate the clutch or throttle. When decelerating, the system automatically opens the throttle valves just enough to increase rpm and match engine speed to the next-lower gear ratio. The result of this hands-free automatic blipping function combines seamlessly with engine braking to create a highly satisfying experience when downshifting.

Lets the rider start the motorcycle with one quick press of the starter button. There is no need to pull in the clutch lever when the transmission is in neutral.

KYB Suspension
43mm gold KYB inverted front forks give a ride that is sporty yet plush. They feature fully adjustable damping, rebound, compression and spring preload. A single KYB rear shock features adjustable rebound damping and spring pre-load.

Brembo Calipers
Brembo radial mount monoblock front brake calipers are mated with Ø310mm floating-mount dual discs to provide powerful braking performance. Each caliper has four opposingØ32mm pistons.

Bosch ABS
The Antilock Brake System (ABS) control unit, produced by BOSCH, is compact and light, weighing in at just 640g. It monitors wheel speed 50 times per wheel rotation, and matches stopping power to available traction.
