Quick Shift System (QSS) for smooth up-shifting even at full throttle
A Quick Shift System (QSS) is adopted to help provide speedy upshifts. When the switch positioned on
the shift lever rod detects motion in the shift lever, it adjusts engine output according to ECU calcula-
tions and instantly cancels out the drive torque of the gear engaged by the clutch dog to promote swifter
shifting of gears. There is a selection of modes for this function to fit specific riding conditions or rider
preferences.
Systems to control machine motion characteristics
Electronic Racing Suspension (ERS) providing integrated control of the front and rear suspensions
(YZF-R1M only)
An Öhlins Electronic Racing Suspension (ERS) is adopted to further bring out performance potential in
circuit riding. Taking data from the IMU and the various sensors, the system’s Suspension Control Unit
(SCU) makes integrated adjustments of both the front and rear suspensions’ compression stroke and
rebound stroke damping force based on running conditions.
With data from the various sensors, the ERS assesses the running conditions and at the same time the
SCU calculates the ideal damping force for the front and rear suspensions. Signals activate the step
motors built into the suspensions to operate the needles that function to adjust the damping force.
This ERS has a choice of “Automatic” and “Manual” modes. Within each of these modes there is also
a selection of three running modes to make a total of six different settings to fit rider preferences or the
riding environment. In addition, two of the running modes in the “Automatic” mode have fine adjustment
functions for the damping force to meet the needs of a wide range of running conditions.
To further increase the latitude for damping force adjustment, the front suspension adopts separate
damping force generating mechanisms for the two sides of the fork, with compression stroke damping
on the left and rebound stroke damping on the right. This design also makes the unit less susceptible
to fluctuations in the hydraulic fluid (oil) pressure and contributes to more stable performance in repe-
titious operation. In addition, it is possible to adjust compression stroke and rebound stroke damping
force independently on both the front and rear suspensions. Also, spring preload is made by means of
a hand-operated nut.
First ABS and Unified Brake System on a Yamaha supersport model
Both an Anti-lock Brake System (ABS), with its contribution to running performance, and Yamaha’s Uni-
fied Brake System, with its capacity to inhibit unwanted machine motion during braking are adopted.
Both of these systems are adopted for the first time on a Yamaha supersport model.
With the Unified Brake System, operating the front brake also generates corresponding brake pressure
at the rear brake. The distribution of braking force is based on input from the IMU regarding the ma-
chine’s attitude and banking angle at the time of brake application.
When brake force is applied to both the front brake lever and the rear brake pedal, the Unified Brake
System functions to control the distribution of braking force between the two brakes, but when only the
rear brake pedal is used, the system operates only the rear brake so that there is no unnatural opera-
tional feeling for the rider.
