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 136 km/h (84 mph) minimum through the Kink, 127 km/h (79 mph) through the long downhill Carousel, and 122 km/h (76 mph) through Turn 11. The slow points cluster earlier and later — Turn 3 is the tightest at a 69 km/h (43 mph) simulated minimum, with Hurry Downs, Turns 4–5, and the Turn 2/10/12 group all in the 82–88 km/h (51–55 mph) band. Simulated lap times span 2:14.2 for the liter-bike model to 2:27.5 for the middleweight twin. All figures on this page are physics-simulation estimates, not measured data.

A 141 m right-hander with a 76.5 m effective radius and a slight 1.2 m drop through the arc. In the simulation the supersport-600 model begins braking about 147 m before turn-in, arrives at 144 km/h (89 mph), and bottoms out at an estimated 108 km/h (67 mph) before rolling back to 137 km/h (85 mph) at exit. The braking zone is the main class differentiator here: the liter-bike model, arriving off a longer run, starts its braking roughly 213 m out, while the middleweight twin needs only about 93 m. Minimum speed is identical across all three classes — the corner radius, not power, sets the floor. Estimates only; see the page assumptions.

The tightest point on the circuit in the model's speed trace. Turn 3 is a left with a 31 m effective radius — less than half that of Turn 2 — covering 114 m on essentially flat ground (0.2 m of drop). The simulation shows a long braking zone: roughly 177 m for the supersport-600 and a substantial 246 m for the liter bike, reflecting how much speed the straight beforehand builds. Entry is estimated at 117 km/h (73 mph), the minimum at just 69 km/h (43 mph) — the lowest simulated speed anywhere on the lap — and the exit at 115 km/h (72 mph). All values are simulation estimates under the stated assumptions.

Canada Corner reverses the elevation story: a 129 m right at 50.3 m effective radius that climbs 4.1 m. The simulation shows one of the longer braking efforts on the lap — approximately 138 m for the supersport-600 and 174 m for the liter bike — into an estimated 128 km/h (80 mph) entry. The modeled minimum is 87 km/h (54 mph), placing it among the slow-corner group with Turns 2 and 12, and the exit is estimated at 125 km/h (78 mph), the uphill grade taxing the drive phase slightly. Per the model's assumptions, the climbing grade also adds normal load under braking. Simulation estimates only.
