It's my understanding the high engagement locks up the clutch quicker with less slipping... I have 370 hours on my 2013 300 plates still in spec... I find the high engagement works the best if ridden aggressively. ...... this is how I have it set on all my bikes kx 65 (7 year old rides this on anything and clutch wear is minimal....)crf150r ( keeps this one from flaming out) cr500 (highly mpdified but is the zstart... 50 hours zero clutch wear all snow) yz250f ktm 300.... man my family needs to find a new hobby

The engagement is only where the clutch opening starts, it still needs to travel from open to full lock out. So the higher in the rpm range you start the higher you need to run the motor to maintain full lock out. So guys lugging there 4s are going to be slipping the clutch more. On a cr 500 it doesn't matter most of those build big end on the pipe power, like an angry 250, so you have to be in it. And same with a 250f you need it higher to avoid the flameout, but motocross you need minimal slip. It's all about where the bike makes power and how to get it to the snow or ground. The other thing is to verify your clutch pack height is in spec, not sure if it's as much of an issue on the 4s(we gave those up 2 years ago) as the 2s core clutches but KTM has 2 different drive plate thickness and the exp ring needs exact tolerance or it can give you false free play gain readings. Learned that the hard way at a national enduro race with my first DDSExp core 2.0 back in 2012 raced my 2011 with a normal pressure plate for 3 weeks till rekluse figured it out.
