Suzuki made a design departure in 2009 when it revamped its GSX-R1000, while leaving the GSX-R600 & GSX-R750 unchanged aesthetically. Finally bringing the two smaller middleweight gixxers in-line with the larger superbike, the 2011 Suzuki GSX-R600 & 2011 Suzuki GSX-R750 get not only a face lift for the new model year, but also a revised engine package that has ample weight trimmings. While the new Suzuki GSX-R600 & GSX-R750’s won’t make more power than the 2010 models, the revised motor and other components shed roughly 20lbs off both the 2011 Suzuki GSX-R600 (413lbs wet) & 2011 Suzuki GSX-R750 (416lbs wet).

Making the weight-loss program possible, Suzuki went in with its surgical knife and dropped weight in a variety of places, primarily focusing on the bikes’ four-cylinder motor. Losing 4lbs in the motor alone, Suzuki lightened the pistons by 14% and the connecting rods by 12%, while increasing the ventilation holes between the cylinders, helping reduce pumping losses and improve combustion efficiency. Relocating the ECU has saved .6lbs in weight from wiring, which is sort of crazy and impressive at the same time. The new exhaust system sheds 3lbs from the prior models’, while revised injectors increase fuel efficiency by 10% and meet the strict Euro III emission standards. More info and photos after the jump.
