Benefit
.
The transmission realizes smooth operation and acceleration, contributing to reduction of engine
power losses.
.
Power band utilization can be maximized by optimizing the gear ratio for GSR750.

(5) Suzuki Exhaust Tuning (SET)

Features
.
SET is an exhaust device that opens/closes a butterfly valve in accordance with the engine rpm.
.
SET system is installed inside the exhaust pipes.
Benefit
.
SET maximizes the exhaust-pulse effect, especially at low-to-mid rpm range, to increase power output.

(6) Transistorized ignition control circuit

Features
.
Transistorized ignition control circuit, which is a feedback of the MotoGP racing technology, is installed.
Benefits
.
The changes of ignition driver allow more detailed control of the ignition logic. In particular,
combustion efficiency when throttle is slightly open is heightened and operating feel is improved.
.
This results in weaker harshness in acceleration and more torque at low-to-mid rpm range.
