.
The powerful 749cm
3
uses a close-ratio six-speed transmission.
.
The 2nd through 6th gears are newly designed for GSR750.
.
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.

Benefit
.
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.
.
SET maximizes the exhaust-pulse effect, especially at low-to-mid rpm range, to increase power output.
(5) Suzuki Exhaust Tuning (SET)
.
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.
