By the way.....I cheapened out on the first one I bought for a rm 250 I turned into a woods bike.......within hours of riding it I knew I made a mistake and bought the 3.0.....perfect so far. The other styles do not feel or work like the stock clutch, only the core 3.0 does. Good Luck, listen to people that have been where your going.

With the Core 3.0 the clutch is engaged at all times until the revs drop to nothing, or when you pull the clutch lever (obviously).
I've finally decided to pull the trigger on the Core exp 3.0.
From what I found, EXP is the Auto clutch disc only and you have to take out two stock plates to fit it, hence potential slippage and stiffer clutch Springs to offset this result in stiffer clutch pull. Fine for easy trail riding or beginners.
Radius is that plus some skinny clutch plates, I believe with stock Springs since the skinny plates mean you can fit the same number as stock. Better for harder riding, but maybe not hardcore racing.
Core EXP is the Auto clutch plus everything you need to keep the stock number of stock clutch plates. So includes bigger clutch cover and different internal parts. Give her hell, it should hold up fine.
To me the more compact design with the Torq Drive, supposed longer life (although proprietary) clutch stack components, lower operating temperatures - that all adds up.
Previous exp didn't have enough friction, they added to stack and employed a custom larger clutch cover to accommodate. Using thinner torq drive solved the problem another way, perhaps a better way.
It seems the RadiusX is a more thought out design on the surface, however, does it work as good or better than the Core EXP 3.0?
I am trying to decide for a 15 KX450F - the stalling in tight, rutted scrambles has to end one way or another.
EDIT: Just watched this video here: https://www.youtube.com/watch?v=kCvV3Psyhn8
Seems like the RadiusX is the way to go: Lighter clutch pull, no clutch creep due to aluminum expansion...to name a couple things.

Much of the info in this thread is incorrect. The Radius X is the TOP LINE product. I know it's less money, but watch the video and you will understand that the Core EXP 3.0 CANNOT be upgraded to a Radius X. The only way the EXP 3.0 might make more sense is if you need to replace certain parts of your OEM clutch. But even then, I think they might recommend replacing the OEM parts and getting a Radius X. If you are just a poser, you might want the EXP 3.0 because you do get a different cover. If that's all you want, you deserve to pay more for an inferior result. As an aside, DON'T advise people if you don't really know the answer. I hope this thread has not caused anyone to buy a 3.0 over a Radius X except for the odd exceptional reason.
I have the Core EXP 3.0 on a 350exc. I love it & I won't own another bike without one now. I ride off-road w/ a little dualsport mixed in. It makes any bike easier to ride & especially a bike w/ a lot of power. I had a yz450f (Z-Start Pro) before my 350exc & it was set up for woods only. That bike was so easy to ride & it was very manageable in the tight stuff. It helps smooth out that jerky 450 power & stalling so you don't get worn out so easy. I liked the Z-start Pro because the clutch pull was so easy. It actually felt like the cable was broken until the bike hit a certain rpm & then it would firm up some. I could use 1 finger all day without getting any fatigue in my hand & that was great for HS's. The Core 3.0 in my 350 has a normal clutch pull.
With that being said, I can't say enough good things about Rekluse & their customer service. Ill be a customer for life.
