Sebring International Raceway
Sebring, Florida · 5.86 km · 3.64 mi · clockwise
Sebring International Raceway in Sebring, Florida is a 5,861 m (3.64 mi) clockwise circuit with 14 numbered corners. The elevation data spans just 17.9 m to 20 m — a range of about 2 m with 4.9 m of cumulative gain per lap — so the simulation treats it as an essentially flat track where corner radius, not grade, shapes the speed profile. The fast sections in the model are the Turn 7 kink and Turn 11 (Bishop Bend), where minimum speeds stay above 140 km/h (87 mph), plus the high-speed exits of Turn 1 and Turn 14 (Sunset Bend) feeding the long straights. The slow section is the Turn 5–6 hairpin pair, where the simulation bottoms out at 63.5 km/h (39 mph), followed by Turn 8 (Cunningham Corner) at 69.8 km/h (43 mph). Simulated lap estimates: 2:11.8 for a liter bike, 2:14.7 for a supersport 600, and 2:20.8 for a middleweight twin — all physics-simulation estimates, not measured data.

The lap opens with a long left-hander — 174 m of arc at an effective radius of 78.4 m, falling a negligible 0.1 m. On the liter bike the simulation starts braking 180 m before turn-in, arrives at 146 km/h (91 mph), holds a 109 km/h (68 mph) minimum, and is back to 150 km/h (93 mph) at the exit. Bike class changes the braking picture more than the corner itself: the supersport 600 model begins slowing at 129 m and the middleweight twin at only 84 m, because the twin simply carries less straightaway speed into the zone. All three classes converge on the same 109 km/h minimum, a reminder that mid-corner speed here is grip-limited, not power-limited. All figures are physics-simulation estimates.

The Hairpin is the tightest corner in the dataset: a right-hander with a 26.7 m effective radius over 135 m of arc. It produces the lowest simulated speed of the lap — a 63.5 km/h (39 mph) minimum shared by all three bike classes. The liter bike model brakes earliest, starting 177 m out from a 114 km/h (71 mph) approach; the supersport 600 begins at 147 m and the twin at 111 m from the same entry speed. Exit speed recovers to 124 km/h (77 mph) on the two larger bikes and 122 km/h (76 mph) on the twin. Only the Turn 1 zone, at 180 m, runs longer anywhere in the Sebring simulation. All numbers are physics-simulation estimates.

Turn 6 immediately answers the Hairpin with a left of identical modeled geometry — the same 26.7 m effective radius and 135 m length, and consequently the same computed speeds: 114 km/h (71 mph) in, 63.5 km/h (39 mph) at the minimum, 124 km/h (77 mph) out. This back-to-back right-left pair at the lap's tightest radius forms the slowest complex on the circuit; the simulation spends more time below 70 km/h here than anywhere else. Brake-start distances again separate the classes — 177 m for the liter bike, 147 m for the 600, 111 m for the twin — while the mid-corner figure is purely grip-limited. Figures are simulation estimates under the stated tire and rider assumptions.
