The all-new, liquid-cooled engine combines the air-cooled unit's 64mm bore with a 5mm longer, 79mm stroke to give a capacity of 1255cc. Key elements include a more compact, semi-stacked gearbox now with six gears instead of five, and the addition of a balance shaft. Suzuki's main requirement when developing this engine was reducing emissions, so in addition to a catalytic converter the latest Bandit also incorporates the firm's Pulsed-AIR (PAIR) system that injects fresh air into the exhaust ports to ignite unburnt hydrocarbons and reduce carbon monoxide emissions. They've added some performance, too: Peak output remains a claimed 98 horsepower, but that number now arrives 1000 rpm earlier, at 7500. Maximum torque, however, is up from 67 lb.-ft. to 79, and is produced at just 3700 rpm instead of the previous 6500. That's some serious low-end grunt.
