Road Atlanta
Braselton, Georgia · 4.13 km · 2.57 mi · clockwise
Road Atlanta in Braselton, Georgia is a 4.14 km (2.57 mi) clockwise circuit with nine mapped corners and one of the larger elevation envelopes in the guide set: the surface runs from 272.7 m to 309.2 m (895–1014 ft), a 36.5 m (120 ft) span, with 79.3 m (260 ft) of cumulative climbing per lap. The simulated speed profile splits the lap cleanly. The fast half runs from the exit of the uphill Turn 1 sweeper — where the model reaches 160 km/h (99 mph) on the 600 and liter bike — through the flowing 3–5 section. The slow half is the back-to-back 6–7–8 complex — where simulated speed bottoms out at 66 km/h (41 mph) in Turn 6, the minimum for the whole lap — and the tight final right, named Motorcycle Turn 12 here. Simulated lap times range from 90.7 s (liter bike) through 93.4 s (Supersport 600) to 98.7 s (middleweight twin). All figures on this page are physics-simulation estimates, not measured data.

A 153 m right-hander at a 54.4 m radius with a modest 4.3 m rise. The approach is where the classes diverge most: the simulation starts braking 165 m out on the liter bike, 129 m on the 600, and just 93 m on the twin, all converging to a 112 km/h (70 mph) entry and a 91 km/h (57 mph) minimum. Exit speeds are 142 km/h (88 mph) for all three classes. Turn 5 closes the fast 3–4–5 sequence in the simulated profile — from here the lap transitions into the slow 6–7–8 complex, and the exit speed achieved here is carried into the brake zone at Turn 6. Simulation estimates only.

A 105 m left at a 44 m effective radius that climbs 2.8 m — and the site of the longest simulated brake zone on the circuit. The liter bike starts braking 216 m before turn-in, the 600 at 174 m, and the twin at 120 m, all arriving at 121 km/h (75 mph). Mid-corner the model holds 82 km/h (51 mph), then builds to 84 km/h (52 mph) at the exit across all three classes. The combination of a tight radius and an uphill grade makes this the corner where the simulation spends the most distance decelerating anywhere on the lap. These are simulation estimates, not measured values.

The final corner, mapped as Motorcycle Turn 12, is the second-slowest point of the entire simulated lap: a 33.5 m effective radius — the second-tightest on the circuit — over just 84 m, dropping 3.8 m on the way in. The model brakes 114–123 m out on the 600 and liter bike (90 m on the twin) from an 87 km/h (54 mph) entry down to a 71 km/h (44 mph) minimum. Because the corner is so short and the run that follows leads back to the start line, exit speed stays close across classes: 128 km/h (80 mph) for the 600 and liter bike, 122 km/h (76 mph) for the twin. The downhill approach adds braking load without changing the shared minimum. All numbers are physics-simulation estimates.
