The GL1200's competitors were becoming more numerous. Last of the big Japanese manufacturers to do so, Suzuki finally entered the marketplace in 1985 with their full-dress tourer, the GV1400 Cavalcade with a DOHC, four valves per cylinder, V4 engine. In 1986 Yamaha enlarged the Venture's V4 engine to 1300cc, and Kawasaki introduced the ZG 1200 Voyager XII with a four-valve, DOHC, Inline-four engine.
