Basically if I remember correctly there are several there was one made for the Falco very hard to find but other than that early mille gen 1 with matching dog bone and linkage. Mine actually uses the Fut links IIRC. You should be able to pick them up for sub 30. Check on rider site all this and a wealth of other Falco stuff on there http://www.ridersite.ws/rs/viewtopic.php?t=9662&highlight=&sid=34d5bcdb838b12671e25231a31b8ec95
That's a White one goes straight on not much worse than an Ohlins in that state
then you need the links specific th the shock IIRC. Tere are a few on ebay at the moment and you could always resell your white one but i understood they were serviceable? Just the original blue ones werent? unless i am thinking of the yellow sachs unit?
The sachas white that I've needs to change. It took him four months ago the service but it has deteriorated. I'd rather put something more reliable. In addition buy the white sachs with 10 years can not trust their state despite the service. I prefer something more quality and service it. That make it give me more confidence. While I have the original blue that I can serve.
