Good looking Bike , what about the S3 Head you like it ?

Is it not for Enduro with 3 Different Head Inserts ?

You're right, the S3 head is marketed as an "Enduro" head. I like it simply because I can control my squish with inserts and base gaskets. The insert I'm running (middle insert) has a squish of 1.7mm, and I'm +30 thou on my deck height. Performs much better than the KTM 300 kit "SX" head with 2mm squish.
