I really like those early marvic's with the polished ally rims and mag spokes.
 they just look right.....
 I had an ex baines mk1 900 superlight which had the same wheels fitted , along with heaps of other tuned up bits. 
 If I remember correctly they are a two peice job, rims are botlted to the spokes, but I maybe wrong on this one,the grey cells are fading fast tonight

 
  cheers
