The engine size was increased to 1340 cc (81.7 cu in) with the compression ratio increasing to 12.5:1. The revised engine has a claimed 12% increase in power to 194 hp (145 kW).

The Suzuki Drive Mode Selector (S-DMS), a technology introduced on the GSX-R line of motorcycles, provides three options of power delivery for a range of touring to wide open high performance. Some of the more notable features include a new 4-2-1-2 exhaust system meets Euro 3 and EPA Tier 2 emission regulations, a slipper clutch, and redesigned bodywork.
