Suzuki has updated its GSX-R1000 sportbike for 2012 with Brembo monobloc calipers and a new single-pipe exhaust system.
Last updated in 2009, the 2012 Suzuki GSX-R1000 also receives a number of updates to the the engine to the wiring harness to even the front tire to to reduce overall weight by 4.4 pounds. The new GSX-R has a claimed curb weight of 447.5 pounds.
The 999cc engine receives new MotoGP-derived pistons, now 11% lighter than the previous version. The new pistons are also largely responsible for a slight boost in compression, from 12.8:1 from 12.9:1. Cam followers are each also 2.5 grams lighter, and revised exhaust cam profile provides less valve overlap. The higher lift exhaust cam profile allowed engineers to boost midrange (roughly between 5500 to 7500 rpm) without sacrificing horsepower in the top of the powerband. New pentagonal-shaped crankcase ventilation holes, just like those first seen earlier this year on the all-new GSX-R600 and 750, reduce pumping losses and is a key contributor to improved mid-range grunt and 8% better fuel economy.
