Not all of them, the U.S. had an air cooled 1985 500 M Star desert sled, but it ran a front disc. Not called a sand spider though.
Your bike screams '84 except for the 5 speed box. The '83 tank would have been because the '84's exhaust burnt holes through the tank in no time at all. The'84's use '83 seat bases with a small piece of molded plastic riveted to the front of the base for the safety seat.
I've owned 2 '84's one SC and one enduro and both where 4 speeds.
I see
just to let you know the bike I am playing with is a EML/Maico kit side car, thats where EML supplied a nacked frame and you took your Solo donour and swapped all the running gear and power plant into it, so when I got the EML/Maico it had 1983 wheels, triple clamps etc etc although on the 12/ 82 front rim some one put the 1985 disc brake into it, apparently the single piston caliper brembo is spongy at best so ive gone to Honda 1984 twin piston calipers.
The Motor wich is not here yet, is the 1983 D362 15## I was told it is a 5 speed, I am NO expert but am trying my best to understand it all, is it true the watercooled came out in 1984 but in the enduro Gs model only because I read they bought out water cooling specialy for sidecar raceing?
So when and what was the 5 speed predominantly in? cheers
