Surely not the update that Gixxer lovers were hoping for, the 2012 Suzuki GSX-R1000 sees a modest retooling as the Japanese company’s liter bike most noticeably goes back to a single exhaust can design. Officially dropping 2kg (4.4 lbs) from its curb weight, we assume the weight savings to the new Suzuki GSX-R1000 can be accounted purely from the new exhaust layout, though Suzuki lists a number of small weight savings throughout the Gixxer’s refined design. Despite a bevy of minor improvements, the big changes include the addition of a beefier midrange, better throttle response, Brembo monoblock calipers with .5mm thinner brake discs, and an improved fuel efficiency by 8%.
