Honda GB500

The Honda GB500 Tourist Trophy, or TT, is an air-cooled single-cylinder solo cafe racer motorcycle. It was first marketed in Japan in 1985 in two 400 cc versions and one 500 cc version, and in 1989 Honda introduced a third 400 cc version for Japan, with a 500 cc version also available in the United States in 1989 and 1990. Its design, mechanical configuration and cafe racer styling recall the British 500 cc singles of the 1950s and 1960s, and the name comes from Great Britain and from the Tourist Trophy, the classic road circuit on the Isle of Man. The engine was derived from the XR500RD, modified with extra flywheel mass, a self-starter and a single carburettor in place of twin carburettors, with a four-valve radial combustion chamber, a tubular frame, wire-spoked wheels with polished alloy rims, a solo seat and a pin-striped fuel tank.
