I believe there is a guy in scotland that has a 200X that was around here for a bit, his picture is in the readers rides section. I'm sure you would be able to get parts from a local motorcycle shop or honda dealer, although prices from the dealer will be sky high. When you get some time maybe ask about the avalibility of 1987 3 wheelers over there in England, they are EXTREMLY rare here in the states.
1986 ATC 250R(for sale), 1963 AceCraft boat w/40HP Evinrude, 1981 Arctic Cat El Tigre' 440 L/C, 1992 GMC Safari Van.
