The Suzuki Hayabusa is a high-performance motorcycle that boasts a number of advanced features designed to enhance the rider’s experience. One of these features is the Suzuki Intelligent Ride System (S.I.R.S.), which includes the Suzuki Drive Mode Selector Alpha (SDMS-α) and a number of other electronic control systems.
The SDMS-α allows riders to select from five different settings, each of which optimizes the performance of the Hayabusa for different road surfaces, riding conditions, and riding styles. There are three factories presets (A, B, C), as well as three user-defined groups of settings (U1, U2, U3) that riders can customize to their preferences.
The current settings can be displayed on the TFT LCD panel located in the center of the instrument cluster and can be changed using switches on the left handlebar.
In addition to the SDMS-α, the S.I.R.S. includes a number of other advanced features that enhance the Hayabusa’s performance and handling.
The Bosch Inertial Measurement Unit (IMU) constantly monitors the pitch, roll, and yaw of the motorcycle, and uses this information to optimize the performance of the S.I.R.S. The Power Mode Selector allows riders to choose between three different engine output modes that control the power delivery to match road and riding conditions.
The Anti-lift Control system maximizes acceleration performance while preventing the front wheel from lifting off the ground, and offers a choice of 10 mode settings.
The Bi-directional Quick Shift System allows riders to shift up or down more quickly and easily without the need to operate the clutch or throttle, and the Engine Brake Control system cancels out the effect of engine braking to provide smoother, more controllable behavior.
Finally, the Motion Track Traction Control System monitors the amount of lean angle and effectively limits slip in corners and on straightaways, providing greater stability and confidence in varying riding conditions. Full review at Suzuki
