Road Atlanta
Braselton, Georgia · 4.14 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 174 km/h (108 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 and the tight final right, named Motorcycle Turn 12 here, where simulated speed bottoms out at 47 km/h (29 mph), the minimum for the whole lap. Simulated lap times range from 93.7 s (liter bike) through 96.2 s (Supersport 600) to 101.5 s (middleweight twin). All figures on this page are physics-simulation estimates, not measured data.

The lap opens with a long right-hander — 234 m of arc at an 84.9 m effective radius, climbing 9.3 m from entry to exit. In the simulation this is the fastest corner on the circuit: the Supersport 600 arrives at 155 km/h (96 mph) after a 111 m brake zone, holds a 114 km/h (71 mph) minimum, and is back to 174 km/h (108 mph) at the exit. The liter bike matches those speeds but needs its brakes 153 m out; the middleweight twin brakes only 69 m before turn-in and exits at a more modest 162 km/h (101 mph), power-limited on the uphill drive. All three classes share the same mid-corner minimum, so the differences here are entirely in braking distance and exit acceleration. Simulation estimates only.

A 180 m left at a 35.4 m effective radius that climbs 8.9 m — and the site of the longest simulated brake zone on the circuit. The liter bike starts braking 213 m before turn-in, the 600 at 177 m, and the twin at 123 m, all arriving at 120 km/h (74 mph). Mid-corner the model holds 73 km/h (45 mph), then builds to 116 km/h (72 mph) at the exit on the two larger bikes and 114 km/h (71 mph) on the twin. The combination of a long arc, a tight radius, and a substantial 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.

Turn 8 mirrors Turn 7 as its right-handed counterpart in the same uphill complex, and the mapped geometry is identical: a 35.4 m effective radius over 180 m with 8.9 m of climb. The simulated numbers match as well — 120 km/h (74 mph) on entry, a 73 km/h (45 mph) minimum, and exits of 116 km/h (72 mph) for the 600 and liter bike versus 114 km/h (71 mph) for the twin. Brake-start distances repeat too: 213 m for the liter bike, 177 m for the 600, 123 m for the twin. Taken together, 7 and 8 form a left-right pair that the model treats as one continuous slow, climbing sequence at the heart of the lap's low-speed half. Physics-simulation estimates only.
