This 1974 Kawasaki H2B is a one-year-only model and represents the final, most refined evolution of Kawasaki’s legendary H2 series. Known for its explosive two-stroke performance and aggressive road presence, the H2B preserved the raw character of its predecessors while offering improved stability and smoother power delivery—making it the most rideable version of the iconic “Widowmaker.” This particular example was discovered as a genuine barn find in the U.S., and has since undergone a sympathetic in-house restoration by TBR Classics. The goal was to retain its originality while bringing the bike back to full mechanical and visual health. The frame has been professionally repainted, the engine fully vapour blasted and rebuilt, and the bodywork refinished in the correct and striking Candy Lime colour. The seat has been re-foamed and re-covered using high-quality, period-accurate materials.
