Chuckwalla Valley Raceway (Counter-clockwise)

Desert Center, California · 4.32 km · 2.68 mi · counterclockwise

Chuckwalla Valley Raceway in Desert Center, California is modeled here in its Counter-clockwise layout: 4,319 m (2.68 mi) of centerline run counter-clockwise through the same 17 numbered corners as the clockwise course. The card keeps the clockwise numbers, so the lap runs Turn 17 down to Turn 1 — ten lefts and seven rights. The circuit is nearly flat, with 10.3 m (34 ft) of total climb. Every speed, distance and lap time on this page is a physics-simulation estimate from track geometry, not measured data. The reference line's slowest point is Turn 9 at 75 km/h (47 mph); its fastest is shared by the Turn 8 exit and the Turn 1 kink at about 172 km/h (107 mph). Simulated laps: 1:48.9 liter bike, 1:49.7 supersport 600, 1:52.3 middleweight twin.

The Bowl is the longest corner on the card: 264 m of left-hand arc at a 71 m effective radius, dropping 0.7 m across its length. The simulated entry is 142 km/h (88 mph) in every class, with brake markers 63 m, 72 m and 45 m out on the supersport 600, liter bike and twin respectively. Minimum speed is 104 km/h (64 mph) for all classes, held through the long middle of the arc. The exit builds to 133 km/h (83 mph) in every class — radius, not power, sets the pace here, which is why the twin matches the larger bikes.

Turn 10 is a 156 m left at a 56.9 m effective radius with a 0.8 m (3 ft) rise, and it carries the longest brake zone on the lap: 117 m on the supersport 600, 150 m on the liter bike and 84 m on the twin, from a 121 km/h (75 mph) entry to a 93 km/h (58 mph) minimum. The exit reads 92 km/h (57 mph), fractionally below the minimum — the line is still slowing as it leaves the arc because Turn 9, the tightest corner on the circuit, follows immediately. Together 10 and 9 form the slowest section of the simulated lap.

Turn 7 is a 159 m left at a 66.5 m effective radius climbing 0.8 m (3 ft). From a 128 km/h (79 mph) entry the model brakes for 90 m on the supersport 600, 105 m on the liter bike and 66 m on the twin — the second-longest zone on the course — to a 100 km/h (62 mph) minimum. The exit is 114 km/h (71 mph) in every class, contained because Turn 6 follows almost at once. The pair of lefts at 7 and 6 sit at the top of the circuit's small elevation profile in this direction.
