Chuckwalla Valley Raceway
Desert Center, California · 4.32 km · 2.68 mi · clockwise
Chuckwalla Valley Raceway in Desert Center, California is modeled here in its Clockwise layout: 4,319 m (2.68 mi) of centerline through seventeen numbered corners — nine rights and eight lefts, with Turn 13 carded as The Bowl. The circuit is nearly flat: the whole lap spans 7.3 m (24 ft) of elevation and no single corner changes height by more than 0.9 m (3 ft). The simulated profile is a run of medium-speed sweeps broken by one slow point, Turn 9, a 37.5 m-radius left with a 75 km/h (47 mph) minimum; the fastest entry is 159 km/h (99 mph) into Turn 15. Simulated laps run from 1:48.9 (liter bike) to 1:52.2 (twin 650). Every figure here is a physics-simulation estimate computed from track geometry, not measured data.

Turn 4 is a 180 m left at an 85.6 m effective radius, falling 0.7 m (2 ft). From a 137 km/h (85 mph) entry the model brakes 81 m out on the supersport 600, 102 m on the liter bike and 57 m on the twin — one of the longer braking events on the lap — to a 114 km/h (71 mph) minimum. The exit is 122.8 km/h (76 mph) in every class, well below the entry: Turn 5 follows immediately, and the reference line is still carrying corner speed rather than driving as it leaves.

Turn 10 is a 174 m right at a 51.1 m effective radius, nearly level (−0.5 m). Its numbers are shaped by Turn 9: the model enters at 89 km/h (55 mph), dips only to an 88.1 km/h (55 mph) minimum, and the 102 m brake marker the solver attaches to it (99 m on the twin) sits upstream on the approach to the previous corner. From the entry the corner is entirely a drive — the exit reaches 150 km/h (93 mph) on the supersport 600 and liter bike and 142.8 km/h (89 mph) on the twin, a gain of almost 62 km/h and the largest in-corner acceleration on the lap.

Turn 11 is a 96 m right with a 102 m effective radius, rising 0.4 m. For the liter bike it carries the longest braking zone on the circuit: from a 151 km/h (94 mph) entry the supersport 600 starts slowing 90 m out, the liter bike 117 m out and the twin 57 m out, down to a 124.4 km/h (77 mph) minimum shared across classes. The exit is 138.9 km/h (86 mph) on the two larger bikes and 135.9 km/h (84 mph) on the twin — below the entry, with the reference line already settling for the left at Turn 12 that follows.
