The clutch is the same. Just small details have changed. So nothing has changed with exp:s and gassers. The thing is that you have to buy exp 2.0 or do other changes (build H***a clutch) to your bike that costs you about same or more money than price difference between exp and core exp.
But if one want's to try even that Rekluse guys says it don't work it's ones choice...
I have full confidence to Rekluse crew and their expertise. So If they say that their certain product don't work with my bike they have sure tested it...
