2. Modifications for low-to-mid rpm range torque
.
The Suzuki Dual Throttle Valve (SDTV) design has two butterfly valves in each throttle body cylinder.
.
The primary valve is connected to the throttle cable, while the opening position of secondary valve
is regulated by a motor controlled by the ECM based on engine rpm, gear position and primary-valve
position.
.
The secondary valve opens/closes to constantly maintain optimum intake velocity.
.
Prompt, linear throttle response allowing quick action of the GSR750
.
Makes for stable combustion when decelerating, transitioning from deceleration to acceleration, etc,
and contributes to allowing sophisticated engine-power control feel.
.
The injector delivers an ultra-fine mist of fuel/air mixture to each cylinder for greater combustion
efficiency, increased power and optimum fuel economy.
.
The injector realizes high combustion performance particularly during ordinary street rides.
.
The cam profiles are designed to optimize the valve timing to tune the GSX-R750 engine – which is
designed keeping in mind racetrack use – to obtain the GSR750 power character that’s more suited to
the streets and winding roads.
.
Thoroughgoing testing by the engineering team resulted in suitable cam profiles that contribute to
both the GSR750’s agile acceleration performance and the improved fuel efficiency.
