== Overview == | |||
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 [[Honda XL600R|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. | |||
