'scuse my ignorance, but what (other than the decals) is the difference between an RF1 and a 750? To the untrained eye, they look identical, right down to the lobster pink swingarm.
Was it the prototype or something?
This is my old 750, polished up with repainted swing arm after a pretty hard life in the Welsh mountains!
Swapped this bike (less the forks) for a '94 Pine Mountain. Stupid... should've kept both, but with a new baby, a morgage and a boat to feed...
The RF-1 ones were made at serotta and they were less than ten. They were the prototype to be used by the proflex team. The 750 were copied from them on year later. Some RF-1's had girvin cranks, the ti flextem and other different bits. Those cranks are impossible to find nowadays.
The swingarm wasn't pink, was neon orange. And the decals too.
There is very few info about them, but retrobikeguy from here knows all about them.
The RF-1 was supposed to be first dual suspension production bike in the world.
