Utah Motorsports Campus (Outer Course)
Tooele, Utah · 4.91 km · 3.05 mi · counterclockwise
The Outer Course at Utah Motorsports Campus in Tooele, Utah is the long perimeter layout: 4,913 m (3.05 mi) of modeled centerline run counter-clockwise through fourteen named corners, from Sunset Bend to Release — ten lefts and four rights. It joins the West side's fast opening to the East side's Attitude corners and Clubhouse Corner by way of Witchcraft, a 143.6 m-radius right entered at 178 km/h (111 mph), the fastest entry on the lap. Black Rock Hairpin, a 36.3 m-radius left, is the slowest point at 74 km/h (46 mph). No corner changes height by more than 2.6 m (9 ft). Simulated laps run from 1:55.2 (liter bike) to 2:01.4 (middleweight twin). Every figure on this page is a physics-simulation estimate computed from track geometry, not measured data.

The lap opens with Sunset Bend, a 222 m left at a 76.2 m effective radius, climbing 1.8 m (6 ft) — the longest corner on the circuit. It also carries the longest braking zone: from a 130 km/h (81 mph) entry the supersport 600 starts slowing 156 m out, the liter bike 219 m out and the middleweight twin 105 m out, down to a 108 km/h (67 mph) minimum shared by every class. The long arc allows a full drive on the way out — 144 km/h (89 mph) for the two larger bikes and 141 km/h (88 mph) for the twin — as the road begins to climb toward Dreamboat.

The tightest corner on the course: 183 m of left-hand arc at a 36.3 m effective radius, falling 1.5 m (5 ft). The simulation brakes long — 153 m on the supersport 600, 183 m on the liter bike, 108 m on the twin, the twin's longest braking zone of the lap — from a 100 km/h (62 mph) entry to a 74 km/h (46 mph) minimum, the slowest point on the lap and the same for every class. The downhill exit builds to 141 km/h (88 mph) on the two larger bikes and 138 km/h (86 mph) on the twin, almost doubling the minimum, onto the run toward Witchcraft.

Clubhouse Corner is a 144 m left with a 71.7 m effective radius, dropping 2.0 m (7 ft) — the biggest descent on the lap. It carries a long braking zone: from a 138 km/h (86 mph) entry on the 600 and liter bike and 139 km/h on the twin, braking starts 87 m, 111 m and 60 m out respectively, to a 104 km/h (65 mph) minimum shared across classes. The downhill exit reaches 141 km/h (87 mph) on the two larger bikes and 138 km/h (86 mph) on the twin before the profile settles for Wind Up.
