GET $1000 ACCESSORY CREDIT! The KTM 890 DUKE redefines the word 'sharp' by adding an extra edge. Powered by an 889 cc parallel-twin nestled into one of the lightest and most compact chassis around, the KTM 890 DUKE boasts the agility you'd expect from a 600 cc, but with the meaty punch of a bigger twin. It doesn't rewrite the mid-sized naked bike rule book. It obliterates it.
