worth knowing: The FGGG1283 ttx inserts are very, very soft, they have the softest standard shim setting, called C20. If you are going to do any racing, you should probably get those reworked
I know that the FGGG1283 are for Sachs but i dont know if it fits my fork.
Is it the shim settings thats different between FGGG1182 and 1283 or are they two types of Sachs fork?
Reading the specs for both kits, they spec the 8762- spring which is 43mm spring. This would indicate they are both for 48 mm sachs forks. I think you need to contact an Ohlins service center or Ohlins directly to get a definite answer to this.
