Overview

Honda GB 500TT Clubman Tourist Trophy











By 1989 the British twin cylinder motorcycles were replaced by British triples and primarily by the Japanese bikes. Each year the Tourist Trophy race was held on the Isle of Man and Honda was determined to bring back the flavor of those British twins with a bike that had look of the Norton and Triumph racing bikes. Honda responded by launching its GB500 (commonly known as the tourist trophy) as a retro-bike with styling and components that recalled fond memories for many motorcyclists of the classic British cycles. The GB500 was a clever package, designed to appeal to a new market that no current motorcycle maker had tapped: the classic, collectible cycles and the older enthusiast. The GB is a sleeved down XL600 engine displacing 498cc.. This means that it has the same stroke as the XL600 i.e 75mm. Its also running 8.9:1 compression so kickstarts are easy. The engine has a gear driven balance shaft that is positioned at the front of the engine. This certainly helps keep it tame all the way to its 7800 red line. The single overhead cam is driven by chain that is on the right hand side of the engine. The Honda RFVC (Radial Four Valve Cam?) valve gear is accessed through the four separate covers.
