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.
Three places to look first
Biggest braking event
Miller Corner (T4): 90.7 → 50.4 km/h over 123.0 m. Brake-point consistency here is worth more than anywhere else on the lap.
Commitment corner
Hayshed (T8): reference minimum 188.0 km/h. Fast corners punish hesitation — min-speed spread here is the classic amateur time leak.
Slowest corner
Miller Corner (T4): 50.4 km/h minimum. Exit drive from here sets the following straight — spread on the exit costs the whole next sector.
