looks like an awesome track for a 2 valver or a supermoto!...but yes...nice intake noises indeed!..and that guy on the 749/999 needs to get his arse off the bike for sure...and is it just me or does it seem like there should be some throttle applied at the sharp slow switchback ( turn 3 and 4 after the straight) to settle the chassis and tighten the chain and help finish that turn better?
It's often called a technical track (polite) - or Mickey Mouse track
They are going to expand next year.
The turns you mention are down hill. I often get in too hot and end up the way you cleverly observe - trail braking and/or closed throttle. I'm working on it. As you can imagine, it's a frequent crash section on this track.
