Oh, and after a bit of googling, it looks like it is the correct body work, just that it is missing the side covers. In most pictures it looks like it's all one piece, but check out this link: http://www.rcycle.com/1974BultacoAlpina250.html
The link you quoted shows a later model, the M116. The M85 that you have came with one piece body work and it was blue with silver trim. A good site that has model numbers and pics of most models is here:
