Easy way to tell at a distance..... rear wheel:
G/S: 3 bolts hold rear wheel on
GS : 4 bolts
and... G/S: bloody expensive now... GS, less so for a younger bike
Now I would dearly love a G/S at the right price, or even a GS. (to replace my 1991 GS...was ace bike....50k plus miles, n only problem was a flat battery....n that was MY fault)...n rear shock died at about 35k miles....
So GS (1989/90 preferably, cheap..... PLEEEASE)
