A limited Champion's Edition 450 EXC issued to mark KTM's 160-plus world championship titles, with the first 250 cc world title in 1974 cited as the starting point. Its extras are a Red Bull Kini Graphics kit, a headlight and taillight package, a skid plate, a front axle pull, black shrouds, a billet fuel cap and other KTM PowerParts items, and the design is credited to two-time motocross world champion Heinz Kinigadner's input.
