2023 Suzuki GSX-R750 Metallic Triton Blue - Metallic Mystic Silver

EFFICIENCY BY DESIGN

Combustion efficiency is a measure of how completely an engine burns its fuel.  Better combustion efficiency can increase power and torque output across the rpm range; improve throttle response, acceleration and fuel mileage; and reduce emissions. Mechanical efficiency is a measure of how much of the power and torque produced by an engine actually reaches the rear wheel.

Reducing mechanical losses by minimizing internal engine friction, reducing the weight of reciprocating internal parts and relieving crankcase pressure can increase mechanical efficiency, putting more of an engine’s output to use actually moving and accelerating the motorcycle and also improving fuel mileage and reducing emissions.

A LIGHTER, MORE COMPACT CHASSIS

The GSX-R750 features a complete chassis design based on a more compact, lighter twin-spar aluminum frame with a 15 mm shorter wheelbase totaling 1,390 mm.

The shorter wheelbase better centers the combined machine/rider mass between the wheels, improving racetrack cornering and also shortening the reach between the seat and the handlebars. The shorter reach and slightly wider handlebar angle make it easier for the rider to re-position their weight while on the racetrack and also improve comfort on longer highway rides.

ENGINE DESIGN

The four-into-one stainless-steel exhaust system features four individual head pipes and a single collector. The mid-pipe located between the collector and the under-engine exhaust chamber carries a Suzuki Exhaust Tuning (SET) servo-controlled butterfly valve to match exhaust system back-pressure to engine rpm, throttle position and gear position, maximizing torque and improving throttle response, especially in the low-to-mid rpm range. The exhaust chamber leads to stainless-steel S-bend pipe and a titanium muffler shaped and positioned to enhance cornering clearance and improve aerodynamics. A reduction in pipe wall thickness and a smaller, more efficient exhaust chamber and muffler combine to make the GSX-R750 system 1,100 grams lighter. A slightly larger-diameter radiator fan mounted on the efficient, trapezoidal, curved radiator turns on and off based on coolant temperature and improves cooling performance.
