Road America

Elkhart Lake, Wisconsin · 6.44 km · 4.00 mi · clockwise

Road America in Elkhart Lake, Wisconsin runs 6,437 m (4.00 mi) clockwise through 12 numbered corners, with the surface ranging between 269 m and 324 m elevation — roughly 54 m (177 ft) of vertical spread and 71 m of cumulative gain per lap. The simulated speed profile splits the lap cleanly: the fast half lives in the middle sector, where the model carries a 128 km/h (80 mph) minimum through the Kink, 137 km/h (85 mph) through downhill Turn 6, and 109 km/h (68 mph) through Turn 11. The slow points cluster earlier and later — Turn 4 is the tightest at a 77 km/h (48 mph) simulated minimum, with Hurry Downs, Turn 3, and the Turn 2/10/12 group all in the 77–98 km/h (48–61 mph) band. Simulated lap times span 2:36.6 for the liter-bike model to 2:43.0 for the middleweight twin. All figures on this page are physics-simulation estimates, not measured data.

Turn 2 tightens things relative to Turn 1: a right-hander of 53.7 m effective radius over 177 m, falling 2 m. The simulated entry is 135 km/h (84 mph) with braking starting about 96 m out for the supersport-600 (117 m for the liter bike, 69 m for the twin). The modeled minimum is 90 km/h (56 mph), and the corner gains speed end to end — the simulation exits at 156 km/h (97 mph), well above its entry, the gentle downhill grade helping the drive phase. This is a physics-simulation estimate computed from track geometry.

Geometrically the opposite of Turn 4 in the computed data: a more open 87.9 m effective radius, a much shorter 45 m length, a gentle 0.6 m descent — and the simulation produces very different numbers. Entry at an estimated 102 km/h (63 mph), a modeled minimum of the same 102 km/h (63 mph), exit up at 140 km/h (87 mph), with braking beginning about 156 m out on the supersport-600 (165 m liter bike, 138 m twin). Taken together, Turns 4 and 5 form a repeated left-left rhythm section where the model's speed floor never changes between classes. These numbers are simulation estimates, not measurements.

Hurry Downs lives up to its name in the elevation data — a 120 m left with a 49.8 m effective radius that continues the descent, dropping another 1.6 m. The simulation brakes roughly 81 m before turn-in (90 m on the liter bike, 66 m on the twin), enters at an estimated 112 km/h (70 mph), and reaches an 87 km/h (54 mph) minimum, among the slower points on the lap. Notably, the modeled exit of 132 km/h (82 mph) is well above the entry, since the downhill run aids acceleration off the apex. All speeds are physics-simulation estimates.
