Suzuki GSX-R600 & GSX-R750 Redesigned

PAR Mel GantlyPosted on

Suzuki’s supersport siblings, the GSX-R600 and GSX-R750, have both undergone complete redesigns for 2011. They are a claimed 9 and 8 kg lighter, respectively, than their 2010 versions, and use 310 mm discs and 32 mm staggered calliper pistons on the front brakes. Vertically staggered, close-ratio transmissions have shorter ratios aimed at better race-start performance and improved corner exit acceleration.  Much attention has been paid to reducing weight, cutting grams from pistons, exhaust, wheel hub, axles and the use of a new and lighter frame.  Rotating the engine back 3 degrees permits a 15 mm shorter wheelbase.    

The 600 and 750 are equipped with a 43 mm Showa Big Piston fork which is fully adjustable and is almost 1 kg lighter than last year’s fork.  New four-piston, monoblock Brembo front brake callipers are also lighter and are said to provide optimal power and feel.  Both GSX-Rs have three-way adjustable footpegs, adjustable shift lever, and shorter fuel tanks.

The GSX-R600 uses lightweight, durable forged pistons designed using Finite Element Method (FEM) and fatigue analysis technology, and camshaft profiles now have a more aggressive valve-lift curve.  Suzuki says these were developed using proven MotoGP racing engine technology, the first time it has done so on its production motorcycles.  Pricing is tba, but we’re guessing you’ll find them on showroom floors by next spring.
