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.
