Efficiency By Design Suzuki Suzuki GSXR 711 2011

The shorter wheelbase better centers the combined machine/rider mass between the wheels, Rotating the engine rearward by 3 degrees around the countershaft sprocket made it possible for the engineers to reduce the distance from the front axle to the swingarm pivot while maintaining the race-proven steering geometry and without losing the needed clearance between the front wheel and the radiator at full wheel travel. The GSX-R750's wheelbase is now 1390 mm. A Lighter, More Compact Chassis The new GSXR750 features a completely new chassis designs, based on a more compact, lighter twin-spar aluminum frame with a 15 mm shorter wheelbase. Suzuki engineers paid special attention to making both the new GSX-R750.

In turn, a better power-to-weight ratio can produce stronger acceleration, better fuel mileage and reduced emissions in many situations. The more power and torque the engine makes and the less the motorcycle weighs, the better the power-to-weight ratio becomes. Performance efficiency is best expressed by the power-to-weight ratio, or, the comparison of a motorcycle's output to a motorcycle's weight. 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.

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