Earlier 900 came with non-adjustable forks, but I'm not sure when they moved to adjustables.
The 600 only came with a single disc, the 750 and 900 with twin discs so if this is the case then it has been upgraded.
Check the frame number on the side of the headstock - it should have a number similar to the engine number. It's not neccessarily a problem as they all have identical frames. eg my bike is a 750 frame with a 900 engine.
If in doubt though, walk away....
