The GB400TT was Honda's 1985 Japanese-market cafe racer, named after the Isle of Man Tourist Trophy and styled like the British racing singles of the 1950s and 60s. Its air-cooled, four-valve 399 cc single drew on Honda's XR/XL dirt-bike engines and sat in a semi-double-cradle frame with spoked 18-inch wheels. The standard model had a dual seat, while the limited MkII added a half fairing and solo seat.
