New Jersey Motorsports Park - Thunderbolt

Millville, New Jersey · 3.50 km · 2.18 mi · clockwise

Thunderbolt is the longer of the two road courses at New Jersey Motorsports Park in Millville. This guide covers the Thunderbolt Classic layout — the 12-turn motorcycle configuration without the Turn 3 chicane — run clockwise over 3.5 km (2.18 mi) through thirteen card corners, Turns 1–12 plus the 11A kink. The circuit is nearly flat: no corner in the model changes height by more than 2.5 m (8 ft). Two slow zones, Turns 4–5 and the Turn 9–10 curl with its 78.9 km/h (49 mph) floor, are separated by fast sweeps: Turn 3 at 181.1 km/h (113 mph) and the Turn 12 kink at 190.5 km/h (118 mph). Simulated lap times run from 83.06 s (liter bike) to 86.06 s (middleweight twin). Every figure here is a physics-simulation estimate.

Motorcycle track guide · simulation estimates · 2026-10-02

  • Layout: Thunderbolt Classic — 3.5 km (2.18 mi), 12 numbered turns plus 11A, run clockwise, no Turn 3 chicane
  • Simulated lap time: 83.97 s supersport 600, 83.06 s liter bike, 86.06 s middleweight twin
  • Simulated average speed: 148.9–150.5 km/h (93–94 mph) for the four-cylinder classes, 145.2 km/h (90 mph) on the twin
  • Fastest corner minimum in the model: Turn 12 at 190.5 km/h (118 mph); Turn 3 sweeps through at 181.1 km/h (113 mph)
  • Slowest corner minimum in the model: Turn 10 at 78.9 km/h (49 mph), followed by Turn 5 at 80.1 km/h (50 mph)
  • Longest braking zone: Turn 1, from 183 m (600 ft) out on the liter bike
  • Nearly flat: the largest single-corner elevation change is 2.5 m (8 ft) of climb through Turn 2
  • Ten of the thirteen card corners turn right; the lefts are Turns 5, 10 and 11A

The lap opens with a right-hander of 84 m (276 ft) effective radius, 135 m long and level within 0.1 m. It carries the longest braking zone on the circuit: in the simulation the supersport 600 arrives at 136.2 km/h (85 mph), starts braking 138 m (453 ft) before turn-in and bottoms at 112.9 km/h (70 mph). The liter bike reaches the same minimum but needs its brakes from 183 m (600 ft) out; the middleweight twin, arriving at 136.3 km/h (85 mph), begins at 96 m (315 ft). All three exit just above their entry speed — the fours at 137.9 km/h (86 mph), the twin at 136 km/h (85 mph) — toward Turn 2.

Turn 4 is where the run from Turn 3 ends: a right of 56.1 m (184 ft) effective radius, 102 m long, falling 0.8 m (3 ft). In the simulation the supersport 600 enters at 107.6 km/h (67 mph) after braking that begins 72 m (236 ft) before turn-in — the liter bike uses the same marker and the twin starts from 69 m (226 ft) — and all three share a 92.2 km/h (57 mph) minimum. The exit is strong for the tightness of the corner: 134.5–134.6 km/h (84 mph) on the four-cylinder bikes and 132.8 km/h (83 mph) on the twin, before the immediate change of direction into the Turn 5 left.

After the fast Turn 6 the circuit tightens. Turn 7 is a 135 m right of 68.4 m (224 ft) effective radius, falling 0.3 m. The simulation enters at 127 km/h (79 mph) on the supersport 600, brakes from 63 m (207 ft) before turn-in — 69 m (226 ft) on the liter bike, 51 m (167 ft) on the twin — and reaches a 101.9 km/h (63 mph) minimum shared by all three classes. The exit, at 121.7 km/h (76 mph), is slower than the entry for every class, because Turn 8 follows immediately and the model carries a similar speed into it rather than driving out of this corner.
