The Ridge Motorsports Park (No Chicane)
Shelton, Washington · 3.91 km · 2.43 mi · counterclockwise
The Ridge Motorsports Park in Shelton, Washington is modeled here on the Full Course without the front-straight chicane: 3,910 m (2.43 mi) run counter-clockwise over the official 16-turn card, Turn 8 split into 8A and 8B — nine rights, eight lefts — with 43.8 m (144 ft) of climbing per lap. The simulation puts the fast end of the lap at Turn 10, a 208.8 m-radius right held at 178 km/h (111 mph), and the slow end at the descending Turn 13, where the model bottoms at 55 km/h (34 mph). Between them sit The Carousel (Turn 6), The Thumb (Turn 11) and the Turn 2–3 climb. Simulated lap estimates run from 1:42.7 (liter bike) to 1:47.8 (middleweight twin). Every figure here is a physics-simulation estimate, not measured data.

Without the chicane, Turn 1 ends an uninterrupted front straight, and the simulation shows it: braking begins 129 m before the corner on the supersport 600, 189 m on the liter bike — the longest brake zone on the lap — and 81 m on the twin. The corner itself is a 69 m left at a 112 m effective radius, level. Entry is 156 km/h (97 mph) in every class and the minimum 130 km/h (81 mph), the second-highest on the circuit. The exit is 141 km/h (88 mph) on the two larger bikes and 139 km/h (86 mph) on the twin, with Turn 2 tightening immediately after.

The climb continues through Turn 3, a 90 m right at a 58.9 m effective radius that rises 7.8 m (26 ft), the largest single-corner gain on the lap. The simulation enters at 104 km/h (65 mph), the Turn 2 exit speed, and holds a 94 km/h (58 mph) minimum; the 120 m brake marker the solver attaches to it (114 m on the twin) reaches back through Turn 2, so the two corners share one braking event. The exit is 122 km/h (76 mph) on the two larger bikes and 120 km/h (75 mph) on the twin.

Turn 13 is the tightest corner on the circuit and the start of its signature descent: a 19.6 m effective radius left that falls 7.7 m (25 ft) over just 90 m. The simulation brakes hard and early — 105 m before turn-in on the supersport 600, 123 m on the liter bike and 78 m on the twin — from a 106 km/h (66 mph) entry to a 55 km/h (34 mph) minimum, the slowest point on the lap in every class. The exit is only 64 km/h (40 mph), because Turn 14 follows straight away and drops the road even more steeply.
