I am trying to decide which Rekluse to get for my 04 YZ450F. The clutches that I am looking at is the EXP 2.0 and the Z-Start Pro. Unfortunately, the Core EXP is not available for my year bike, so the only options are the EXP 2.0 and the Z-Start Pro. I am leaning towards the Z-Start Pro because it doesn't remove some of the clutch components like the EXP does. I am wondering which clutch is better suited to my bike? I have the bike set up for woods riding, which is all that I ride. If anyone has any input on which clutch would be better, please let me know. This topic has probably been covered already, and I have searched already, but I still have some more questions about these clutches.
