The reference below is a minimum-lap-time motorcycle line solved on this circuit's verified bike layout and measured track width, with speeds from a quasi-steady-state motorcycle model. It is a ceiling under ideal assumptions — use it to see where your headroom lives, then drop your own session file to measure yours.

Where the lap is won

Three places to look first

Biggest braking event

Turn 9: 158.7 → 115.4 km/h over 15.0 m. Brake-point consistency here is worth more than anywhere else on the lap.

Commitment corner

Turn 10: reference minimum 161.3 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.

Slowest corner

Turn 13: 37.6 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
