the rekluse is in my opinion the one to get.. very easy to install/setup, first time I did it it took under an hour and that includes walking inside and getting another beer. Im sure you read it by now but the Rekluse has an optional clutch perch adjuster.. this allows you to use your clutch just as you would normally,, and also allows you to quickly adjust the engagement of the clutch.. as far as being like a 4-wheeler clutch,, I don't think that is exactly true.. you can adjust how much the clutch slips before it locks up totally.. its GREAT for woodsriding which is what I do. And no I CANNOT stall my bike with this clutch.. brake slide into corners without even looking at the clutch lever, Drop your bike, no problem, pick it up and twist the gas... I have it set up to engage pretty early in the revs,, but for mx you can install the heavier spring in the perch adjuster (15mins max) that would automatically slip, read feather, the clutch coming out of turns allowing you to keep it in the power without touching the clutch.. It takes some getting used to but everyone who rides my bike LOVES it..It really is like having a pro working the clutch for you..
